PDF to Video Converter

Upload the PDF to DistilBook, review the auto-written narration, and approve it. The system generates slides and an AI voiceover for each one, then merges them into a single video with audio and subtitles. No editing software is involved.

This is a hard limit worth checking before you upload, because the file is rejected rather than trimmed. The free tier and the $20 Basic plan accept up to 10 pages, the $50 Pro plan up to 30, and the $100 Max plan is effectively unlimited. File size is generous at 500MB, so page count is what binds. If your document is longer than your plan allows, split it by chapter or section and make one video per part, which usually works better anyway.

Yes. Pages with little or no selectable text are run through OCR automatically before script writing.

Figures from the PDF inform the slide artwork, and you can place specific images into any slide with the built-in editor before rendering.

A slide costs 10 credits. Signup grants 10 credits with no card collected, enough for the first slide of your video, which you can watch in full in the browser; the rest unlocks on a paid plan. Paid plans are Basic at $20 per month for 230 credits, Pro at $50 for 650, and Max at $100 for 1,340. An 8 slide video is 80 credits, so roughly $7 on the Basic plan. Removing the watermark and exporting MP4 require a paid plan.

Two things. Most tools in this category put an AI avatar on screen reading your document, or cut stock footage against it. DistilBook illustrates the content instead: original artwork generated per slide from that slide's meaning, so a diagram-heavy page does not become a stranger in a suit talking over b-roll. The second is the pause. The narration is written and shown to you before any audio or artwork exists, so you correct the script rather than re-rendering a finished video. For anything where a paraphrase changes the meaning, that step is the whole point.

Yes, on any paid plan, at up to 1440p, with subtitles generated from the narration. On the free tier you get a shareable link and can watch the whole video in the browser, but it carries a watermark and MP4 export is not included.

It depends on the style you pick. Whiteboard runs about 2 minutes of finished video per slide, so a 5 slide video is roughly 10 minutes. The motion-graphics styles are faster paced at about 25 seconds per slide, so the same 5 slides is about 2 minutes. There is a ceiling of 18 slides for whiteboard and 20 for motion graphics.

No. Narration is generated for you: pick an AI voice in any of the 20 languages, or on the Pro and Max plans clone your own voice once from about a minute of recording on My Voices and narrate with it. Uploading a finished audio track to replace the narration isn't supported, so if the video must use a specific recording word for word, record over the exported video instead.

Word documents, Markdown and plain text files upload the same way. You can also paste an article URL and it will read the page, or type a written prompt if you have no source document at all. Images can be used as slide input too. Uploads are capped at 500MB, though for PDFs the page limit is what you will hit first.

Yes. DistilBook makes both 16:9 landscape and 9:16 vertical video. Choose 9:16 Portrait under Aspect ratio when you create the video, for the whiteboard style or a motion-graphics style, and it is composed as a true vertical video for Shorts, Reels and TikTok.

It depends on what you want on screen. If you want an explainer that draws a new illustration for each idea in your PDF, with a narration script you approve first and your logo from the $20 plan, DistilBook is built for exactly that. If you want an AI presenter talking over your content, HeyGen or Synthesia fit better. If you only need your PDF pages on screen with a voice reading them, a slideshow-style converter is simpler.
