How to convert pitch decks and whitepapers to LinkedIn slides

A pitch deck and a whitepaper are both files a company already paid to make. LinkedIn slides are a different file. LinkedIn paginates a PDF, and each page is a slide someone swipes on a phone. Converting the source means throwing most of it away, keeping one claim you would say in public, and designing a new PDF of 2 to 8 pages. Uploading the investor deck or the full whitepaper does the pagination. It leaves the original pages looking like the original pages.

Boykli runs that conversion in two passes. On Create posts, Document mode reads a text PDF, a Word file, or a Markdown file and writes one LinkedIn post from a single idea. The carousel page does not take the file. You paste an outline of that idea into the topic box, up to 2,000 characters, and it designs a new PDF: square or portrait, with a document title and a caption. You download that PDF or publish it on the personal profile you connect. The generic file path, including memos, is PDF to LinkedIn carousel. This page is the pitch-deck path and the whitepaper path, because those two files fail for different reasons.

A deck and a whitepaper waste different pages

A seed deck is usually 10 to 16 slides, exported at 16:9. The faces are labels, logos, and charts. The argument often lives in speaker notes, or in the founder's mouth. A whitepaper is usually 15 to 40 pages of prose: an executive summary that lists every finding, a method, one or two results that matter, footnotes, and a legal close. Both files can be "the source." Only one claim in each file is a LinkedIn deck.

Four decisions sit in front of the layout, and they are not the same decision twice:

1. Which claim is public. A raise amount, a cap table, an unannounced logo, and a pipeline number stay in the room where the deck was shown. A LinkedIn slide is a document anyone can download.
2. Which claim is the deck. One PDF, one point. The market slide and the product slide are two creates. The four findings in an executive summary are four creates.
3. Where the words actually are. On a pitch deck they are often in the notes, or inside a chart image. On a whitepaper they are in a section, and the abstract is a list, not the claim.
4. How many new pages that claim can hold. The carousel form stops at 8. A cover, the proof, and a close usually fit in 5 to 7. LinkedIn will paginate up to 300 pages. A 300-page swipe is the original document with a new filename.

The cut stays with the person whose name is on the post. The longer version of that choice is building Boykli.

Four ways people turn these files into slides

The last row is the workflow below. The first row is what happens when "we already have a deck" is treated as "LinkedIn already has slides."

What the extractor keeps from each file

Document mode accepts .pdf, .docx, and .md. It does not accept .ppt or .pptx. A Google Doc is none of those three until you download one tab. The tab dialog, the comment that never enters the body, and which download the reader will open are in how to convert Google Docs into LinkedIn slide decks. A Markdown file is the third type, and the bytes are the source, headings and fences included. The traps that belong to .md — front matter, a code fence that eats the character budget, and a README that holds several arguments — are in how to convert Markdown files to LinkedIn carousel slides. A PowerPoint, Keynote, or Google Slides file has to be exported first. The upload must be 7 MB or smaller. After parsing, the text must be 80,000 characters or fewer, and it must contain at least 80 non-whitespace characters. Below that, the API refuses the file. A photo of a slide, a chart-only PDF, or an empty export has no text layer. There is no OCR step.

What comes out is a string. For a whitepaper, headings often survive as lines, and a single column reads in order. Footers, page numbers, and a repeated confidentiality banner show up on every page and waste the character budget. For a pitch deck, text boxes are often stored in an order that is not the visual order: a footnote, then a title, then a label from the previous slide. Charts, logos, and product screenshots do not become images on the later carousel. Slides are HTML and CSS. If a number matters, it has to be in the extracted text, and you have to see it in the draft.

Speaker notes are the usual miss on a deck. A default "export to PDF" writes the slide faces. If the faces are a chart and three words, search the PDF for the sentence you would actually say. If search finds nothing, the argument never left the notes. Export again with notes included, or paste the notes for that one slide into a .docx or .md and upload that. Uploading both the faces and a 40-page appendix of backup slides makes the extract worse, not better.

The writer is instructed to amplify one idea. If you fill Optional Idea / Brief, that brief picks the section. "Only the setup-time change. Keep 46 days and 11 days. Ignore the raise." is a brief. An empty brief asks for the single strongest lesson in the whole file. On a whitepaper, that lesson is often the executive summary, which lists four findings and teaches none of them. On a pitch deck, an empty brief often lands on the problem slide, because that slide has the most words. The post is 700 to 1,400 characters. It does not say "the document" or "this report." It does not add hashtags, emoji, or a statistic that was not in the extract. Tones are Teach & Explain, Analytical, Step-by-Step, and Thought Leader. You can refine that draft twice. A third pass is a new write.

That post is a filter, not the slides. Copy a tighter outline into the carousel topic. The map of topic, idea, and file starts is LinkedIn carousel generator. Page size, the 220px safe zone, and why a 16:9 board slide is the wrong canvas are in LinkedIn carousel dimensions.

A pitch deck, worked

Source: a 12-slide seed deck, exported from Google Slides to PDF, 4.2 MB. Slide 1 is the company name. Slides 2 and 3 are the problem, mostly a screenshot. Slide 4 is the product. Slide 5 is a market chart with no sentence under it. Slide 6 is traction: a bar chart. The speaker notes on slide 6, included in this export, say the median setup went from 46 days to 11 days after the team dropped the SSO checklist. Slides 7 through 12 are the model, the raise, the team, and a logo wall.

A raw upload to LinkedIn would swipe the raise and the logo wall. Search-in-PDF finds "46 days" only because the notes were included. The bar chart itself contributes nothing to the text layer.

Pass 1, on Create posts:

1. Document mode. Upload the PDF. Leave the call-to-action switch off. The close of this post is the lesson, not a request for a meeting.
2. Brief: "Only the setup-time change in the notes on the traction slide. Keep 46 days and 11 days. Skip the raise, the team, the logos, and the market chart."
3. Tone: Step-by-Step, because the useful shape is what they stopped doing, in order. Analytical fits if the point is the two numbers and nothing else. Thought Leader fits the implication, still using only those notes.
4. Write. Read the 700–1,400 character post. If 46 days became "about six weeks," or if a market size appears, the brief was too loose or the extract pulled a label from another slide. Fix the brief and refine, or write again. Two refinements are the limit on that draft.
5. The accepted lesson is one paragraph you would say to a stranger: what changed, the two numbers, the order. The raise is not in that paragraph. If you would not put the number on a public page, it does not go in the brief.

Pass 2, on the carousel page:

1. Paste an outline, not the deck and not the whole post. A topic that works: "Cover: setup went from 46 days to 11. Slide 2: the checklist we deleted. Slide 3: who can turn the account on. Slide 4: the step we kept. Close: the one rule to copy. Do not add a raise, a market size, or other numbers."
2. Tone: Normal. Humor would treat the implementation as a joke.
3. Slide count: 5, matching the outline. Default is 5. The form allows 2 through 8.
4. Shape: Portrait, 1080 by 1350, because each step is two short lines plus a label. Square is 1080 by 1080 when the line is a single card. The original 16:9 frames are not a choice here.
5. Design: Infographic / Data Guide for a sequence. Neo-Brutalist is the default when the deck should look less like a board appendix. If brand-kit colors are on, the only design available is Normal. The other seven stay disabled until brand colors are off.
6. Model: Grok 4.6 is the default. The picker also offers Gemini 3.5 Flash, Claude Sonnet 5, and GPT-5.6 Terra. Document mode writes with the post model. The deck uses the carousel model.
7. Create. A large deck can take a few minutes. The page stops the attempt at about eight minutes.
8. Read every slide against the notes. The prompt tells the model not to invent statistics. It still writes the lines. A third duration, or a funding figure, is a failed deck. Change the topic and create again. There is no per-box editor.
9. Set the document title, up to 120 characters. LinkedIn shows it as the name of the PDF. The caption is separate, up to 3,000 characters, and it is the commentary in the feed. The title is required when you add the PDF to the queue.
10. Download the PDF, post it now, or queue it. Publishing uses the personal profile from LinkedIn OAuth. Company pages are outside the product.

The file you publish is the new PDF. The seed deck stays where you stored it. They are different records. A founder who wants the audience to recognize the company, and still keep the raise off the feed, is doing the same split described in B2B founder LinkedIn branding: one public claim, not the whole room.

A whitepaper, worked

Source: a 22-page text PDF, 2.1 MB, about 28,000 characters, titled as an internal methods paper and cleared for a public excerpt. Pages 1 and 2 are an executive summary with four findings. Pages 8 through 11 are the change that mattered: a matching rule that cut invoice exceptions from 14% to 3%. Pages 18 through 22 are citations and a vendor matrix. Search-in-PDF finds "14%" in the body, not only in a chart.

An empty brief would chase the summary, because that is where the file is loudest. The summary names four findings and explains none of them. A carousel of "four things we learned" is the executive summary with bigger type.

Pass 1:

1. Document mode. Upload the PDF. If the file were over 7 MB, or the extract over 80,000 characters, delete the citation appendix in the export and upload the shorter file. Hoping the brief ignores 40 pages of footnotes is weaker than removing those pages.
2. Brief: "Pages on the matching rule only. Keep 14% and 3%. Skip the other three findings and the vendor matrix."
3. Tone: Analytical. The point is the before and after, plus the rule that produced it. Step-by-Step fits if you want the sequence of the rule instead of the comparison.
4. Write. The draft should keep both percentages. If a fifth finding appears, the extract leaked the summary into the post. Refine, up to twice.
5. Accept one paragraph: the rule, the two rates, what the rule refuses to match. That paragraph is the only material the slides are allowed to know.

Pass 2 is the same carousel form as the deck. A topic that works: "Cover: invoice exceptions went from 14% to 3%. Slide 2: what we match on now. Slide 3: what we stopped fuzzy-matching. Slide 4: who reviews the leftover queue. Close: the rule to copy. Do not add the other findings." Six slides is the count if the leftover queue needs its own page. Design: Infographic / Data Guide. Portrait if each rule is a sentence. Square if each rule is a labeled card.

If the same paper also lives as a public HTML article, the URL path is separate. Article mode fetches the page and writes one post. It does not read the PDF, and the carousel page still needs the outline you paste. That path is article to LinkedIn carousel. Use the file when the public page is a gate, a scan, or a shorter excerpt than the section you want.

How many slides each source can support

Eight is a ceiling, not a goal. The prompt also caps density: about five bullets or four cards, body type at 21px or larger on the square canvas. A topic that says "put the whole checklist on slide 3" produces a cramped slide or a dropped line. Split the checklist in the outline.

Series mode on Create posts writes several text posts from source text. It does not emit several carousel PDFs. One deck is one create.

The order of operations

1. Decide the public claim before you export. Write one sentence: the change, the two numbers, and what you will leave out. If that sentence mentions the round, the valuation, or a logo you cannot name, pick a different sentence.
2. For a deck, export PDF with the notes for that claim, or paste those notes into Word or Markdown. Open the file and search for a sentence you know is there. If search finds nothing, the upload will fail or the draft will be labels.
3. For a whitepaper, export a text PDF of the section, or the whole paper if it is under 7 MB and under 80,000 characters of extract. Delete the appendix you do not want rather than hoping the brief skips it. A scan needs a text export or a typed .docx. There is no OCR.
4. On Create posts, choose Document. Upload .pdf, .docx, or .md.
5. Write the brief as a cut. Name the slide or the section, the claim, and the numbers to keep. Name what to ignore, especially the raise, the other findings, and the vendor list.
6. Pick the tone. Step-by-Step for a procedure in the notes. Analytical when the point is the comparison. Teach & Explain for a framework. Thought Leader for the implication, still using only what the file supports.
7. Read the post. Refine at most twice. If the lesson is the wrong finding, the slides will be a polished version of the wrong finding.
8. Rewrite the lesson as a slide outline in the carousel topic. Name the cover and the close. Stay inside 2,000 characters. Do not paste the whitepaper.
9. Set Normal or Humor, ratio, design, model, and slide count. Save the brand kit first if you changed canvas, accent, logo, photo, or handle. An unsaved kit blocks create. Author strip and logo are toggles. The generator does not invent a handle.
10. Create, then read the slides against the source sentence. Download or publish only after that read.
11. Title, caption, then the personal profile: post now or add to the queue. The document-specific path, including why LinkedIn's composer often has no clock on a PDF and what the slot actually sends, is in How to schedule a PDF on LinkedIn.

Managed includes 210 posts and 150 carousels in the month, plus 150 images, 25 Voice Agent sessions, and 130 post refinements. The document post counts as a post. The carousel create counts as a carousel. Downloading the same PDF again does not. BYOK is the same screens with your OpenRouter key for chat and images and your Google AI Studio key for Voice Agent, and Boykli does not add a generation cap on that seat. You still pay those providers. Both seats are $29 and $88 a month on boykli.com. A paid seat is required before the app will write, create a carousel, publish, or schedule. Browsing Radar and Algorithm is open without one.

FAQ

Can I upload the PowerPoint or Keynote file?

No. Document mode accepts .pdf, .docx, and .md. Export a text PDF, or paste the speaker notes into Word or Markdown. The carousel you publish later is also a PDF. Boykli's queue sends that rendered PDF. It does not send the original slide file.

Will the charts, logos, and screenshots become slides?

No. Extraction is text. A bar chart of 46 days and 11 days contributes those numbers only when the numbers are written on the page or in the notes. A logo wall does not become a row of images. If the claim the chart supports is real, write that claim into the brief and the topic.

Should I post the investor deck as the LinkedIn document?

Only when those exact pages are what you want a stranger to download. The raise, the cap table, unannounced customers, and backup slides travel with the file. A LinkedIn document post can be saved. The conversion on this page builds a shorter public PDF from one claim, and leaves the original deck where you stored it.

The whitepaper is 90 pages and the upload failed.

The ceilings are 7 MB and 80,000 characters of extracted text. A long citation appendix and a repeated footer will hit the character cap before the result section is the whole story. Export the section you named in the brief, confirm search still finds the numbers, and upload that file.

The PDF is a scan of a printed whitepaper, or a deck of pictures.

If the readable text is under 80 characters, the API refuses it. There is no OCR. Export a text-based PDF from the source tool, or type the section into a .docx or .md.

Can one deck or one whitepaper become several LinkedIn carousels?

Yes, as separate creates. Each pass through Document mode is one post about one idea. Each carousel topic is one deck. The market slide and the traction notes are two topics. The four findings in an executive summary are four topics if you intend to publish all four. Series mode writes multiple text posts and does not build the PDFs.

How do I change a sentence on slide 4?

Edit the document title and the caption in place. Slide copy is part of the generated design. Change the topic and create again. That new create counts toward the Managed carousel cap, or toward your provider usage on BYOK.

What do I pay to run this?

The seat is $29 a month on BYOK or $88 a month on Managed. Managed includes 150 carousel generations and 210 posts in the month. BYOK has no Boykli monthly cap. The document write and the carousel create are both gated by the seat.

Can I queue the new PDF?

Yes, on the personal profile you connect. The queue asks for a document title. You set the days, the time of day, and the timezone. The next item takes the next open slot. It does not post as a company page.
