Video to PDF — Slide Extractor
Turn a slide-based video — a lecture, webinar or screencast — into a clean PDF. This tool scans the whole clip on your device, detects every distinct slide, drops duplicates and transition frames, and writes one slide per page — without uploading a thing.
Detects real slide changes
Background subtraction plus perceptual hashing find each moment the content settles into a new slide — ignoring the cursor, a laser pointer, a talking-head webcam or video playback, so you get clean key slides, not blurry transitions.
Deduplicated, one slide per page
Re-shown or scrolled-back slides are recognised and dropped, and animated bullet builds collapse to their final state. Each kept slide becomes one PDF page at its native aspect — ready to read, print or annotate.
On-device and private
The whole video is decoded and analysed in your browser with WebCodecs and a WebAssembly vision engine. Your footage never leaves your device — no upload, no account, no watermark.
How to convert a video to PDF slides
- Open the tool and add your video. Open Pixlane Video to PDF Slide Extractor and drop your MP4 or MOV (or choose a file). It loads instantly and is processed on your device — nothing is uploaded.
- Adjust. Pick a sensitivity and scan rate, then let the tool scan the whole clip on-device, detect each distinct slide and build the PDF — one slide per page.
- Export and download. Click Extract slides and download the result — free, no watermark, no signup.
Frequently asked questions
What kind of videos work best?
Slide-based content: recorded lectures, conference talks, webinars, course videos and screencasts where the screen holds on each slide for a moment. Full-screen slides work best; a small webcam overlay in the corner is fine.
How does it find the slides?
It samples the video a few frames per second, runs a background-subtraction model and a perceptual hash on each frame, and captures a slide once the content stops changing (settles). Duplicate and mid-transition frames are filtered out.
Will it capture duplicate slides?
No — a perceptual hash compares each new slide to the ones already kept, so a slide that is re-shown or scrolled back to is dropped, and an animated bullet build is collapsed to its final state.
Is anything uploaded?
No. Decoding, slide detection and PDF generation all run locally in your browser. Nothing is sent to a server, and there is no account or watermark.
Can I control how many slides I get?
Yes. The sensitivity setting trades off capturing every change versus merging near-identical slides, and the scan rate controls how finely the video is sampled — useful for fast slideshows.
