Video to WebP/APNG Converter
Convert a video clip into an animated WebP or APNG image.
About this tool
Cuts a section of a video and converts it to an animated WebP or APNG — both support full 24-bit color with transparency (unlike GIF's limited palette), and modern browsers display them natively. WebP is usually the smaller file; APNG has slightly broader support in older image viewers. Runs entirely in your browser using ffmpeg.wasm; your video is never uploaded anywhere.
The ffmpeg engine (about 32MB) is only downloaded the first time you use this tool, not when the page loads.
Frequently asked questions
- WebP or APNG — which should I pick?
- Animated WebP is almost always noticeably smaller for the same visual quality, and is well supported by current browsers and most modern apps — it's the better default. APNG can be worth using if you specifically need broader legacy compatibility.
- Is there a length or resolution limit?
- No hard limit, but longer clips, higher frame rates, and larger widths all increase processing time and file size — keep clips short for a reasonable file size, the same as with GIF conversion.
- Is my video uploaded anywhere?
- No — the entire conversion, including the ffmpeg engine itself, runs locally in your browser via WebAssembly. Nothing is sent to any server.
