Video to Flipbook
Turn a few seconds of video into a paper flip book: numbered cards with a binding strip and cut lines, ready to print, cut, stack and flip. Made on this device; the video is never uploaded.
Pick up to 10 seconds; 2 to 4 seconds makes a book that is easy to hold.
Clip
Type seconds (1.2) or minutes:seconds (1:05.5), or drag the handles.

Flip preview
Open a video: the cards appear here and flip at the chosen speed, exactly as they will print.
Look
Print at 100% (Actual size), not Fit to page; the last page has a 50 mm line to check.
Privacy: the video is read in your browser and never uploaded. The browser's own player decodes it, the pictures are drawn on a canvas on this page and the PDF is written here too. The only network traffic after loading is an anonymous page count and two fixed event names: flipbook-open (a video was opened) and flipbook-print (a PDF was saved or printed). Never the file, its name, your title or anything in them.
How to make a flip book from a video
- Open the video. Tap Open a video or drop the file on the box. The page uses this browser's own player, so it opens what the browser plays and says so plainly when it cannot.
- Choose the moment. Drag the two handles on the frame strip, or type the start and end times. It starts with the first 3 seconds. A good flip book moment is one clear movement: a kiss, a jump, a ball caught, a wave.
- Pick the speed. 8, 10 or 12 pictures a second. The page count updates as you go (3.0 s × 10 = 30 pages). More pictures a second is smoother but a thicker stack.
- Set the look. Fill the card crops the frame to the card's shape (slide the crop position to keep the face in); Fit whole frame keeps all of it with white bands. Black and white and Brighter for print help on home printers.
- Watch the flip preview. It plays exactly the cards that will print, at the chosen speed.
- Save the PDF (or Print), and print it at 100%.
How to bind it
- Cut on the dashed lines. Each card has its number on the grey strip at its left.
- Stack in number order with 1 on top (the cover card above it). The cards print in number order, left to right and top to bottom, so sheet by sheet they come off the cutting mat in order.
- Clip or staple the grey strip: a bulldog clip, two staples, or a tight rubber band or tape. Tap the strip edges level first.
- Flip with your thumb: hold the bound strip, bend the free edges and let the cards slip off one by one, from 1 onward.
What is on the PDF
A4 (210 × 297 mm) or US Letter (8.5 × 11 in), at true size. Each sheet holds 10 cards in a 2 × 5 grid inside a 10 mm margin, with dashed cut lines that run a few millimetres into the margin so you can line up a ruler. On A4 a card is 95 × 55 mm; on Letter 98 × 52 mm. The left 16 mm of every card is a grey binding strip with the page number; the picture sits beside it (74 × 50 mm on A4, 77 × 47 mm on Letter), drawn at 200 pixels per inch. With a cover card it takes the first cell and the numbered cards follow. The last page lists the cut, stack and bind steps and has a 50 mm line, so you can check with a ruler that the printer did not shrink it. 3 seconds at 10 a second is 30 cards on 3 sheets plus the steps page.
What it cannot do
- No sound. A flip book is silent.
- It does not print, bind or post a flip book for you. Nothing is sold or ordered here: you get a PDF and print it yourself.
- It opens only what this browser decodes. MP4 (H.264) and WebM open in every current browser. HEVC (H.265), the iPhone default, opens in Safari and only on some other browsers and devices. When a file will not open, the page names it and says it could not be decoded; convert it to MP4 (H.264) and try again.
- Pictures are taken by time. Card k is the frame showing at start + k ÷ speed. Phone video often has a variable frame rate, and 12 a second from a 10 frames-a-second video asks for more pictures than there are frames, so two neighbouring cards can show the same picture.
- At most 10 seconds, 120 cards. The cap comes from measuring this page (2026-10-29, headless Chrome on a 4-core server): seeking a 1080p 30 fps H.264 video and copying one picture took about 130 to 150 ms, a 720p one about 90 ms, so a full 120-page book takes 11 to 18 s to prepare, and a phone can be slower. Each page is kept in memory as two JPEGs (the frame at no more than 960 px, and the card picture at 583 × 397 px), about 50 KB together for that test video and more for detailed camera footage; 120 pages wrote a 2.2 MB PDF. 120 cards are also 12 sheets to cut, already a thick book to clip.
- Typed text uses a standard PDF font (Helvetica). It covers English and Western European letters (é, ü, ø, ß and the like). Any other character, such as emoji, Greek, Cyrillic or Chinese, prints as "?" on the cover card.
Questions
How do I make a flip book from a video?
Open the video on this page, drag the start and end handles around the moment you want (up to 10 seconds; 2 to 4 seconds makes a book that is easy to hold), pick 8, 10 or 12 pictures a second and watch the flip preview. Save the PDF, print it at 100% (Actual size), cut along the dashed lines, stack the cards with 1 on top, clip or staple the grey strip, and flip. 3 seconds at 10 a second is 30 cards on 3 sheets.
What paper should I print a flip book on?
Thicker paper flips better.
How many pages should a flip book have?
Pages = seconds × pictures a second. 2 seconds at 10 a second is 20 cards, 3 seconds is 30, which is a comfortable stack for a clip or two staples. The page shows the count as you move the handles, and caps a book at 10 seconds, 120 cards at 12 a second.
Is my video uploaded?
No. The browser's own player decodes the video on your device, the pictures are drawn on a canvas on this page and the PDF is written in the page. The only network traffic after loading is an anonymous page count and two fixed event names, flipbook-open and flipbook-print.
