Video to WebP Converter

An animated WebP does what a GIF does — a short silent loop that plays wherever an image can go — but with millions of colours instead of 256 and usually a fraction of the file size. This converter cuts a moment out of a video and saves it as an animated WebP for websites, documentation, chat stickers and product pages. Transparent WebM clips (stickers and overlays) stay transparent, soft edges included. It runs in your browser with the ffmpeg engine (about 30 MB, downloaded once); the video is never uploaded.

How to use this tool

1. Choose a video (MP4, MOV, WebM, MKV, AVI and others).
2. Enter where to start and how many seconds to use (up to 30).
3. Pick the frame rate, width and quality; "Lossless" suits screen recordings and cartoons.
4. Choose how often it loops, then download the .webp file.

Formula

Frames ≈ seconds used × frame rate

Each frame is compressed with libwebp (lossy VP8 or lossless VP8L). Frames that do not change are merged into one longer frame, and only the part of a frame that changed is stored, so the frame count reported can be lower than seconds × rate for still scenes. Width is never enlarged; portrait phone videos stay upright.

Example

Taking 4 seconds at 12 fps gives 4 × 12 = 48 frames. At 480 px and quality 75 a typical phone clip lands around 300–900 KB — often a third to a fifth of the same clip as a GIF, with smoother colour.
