MP4 to animated WEBP
Convert MP4 to animated WebP (~480p / 12fps cap) locally in the browser with ffmpeg.wasm—often smaller than GIF for similar motion.
How it works
- Export MP4 as animated WebP for smaller files than many GIFs—capped to about 480p / 12fps in the browser for stability.
- Audio is omitted; output is an animated image, not a video container.
FAQ
- Are my files uploaded to your servers?
- No. By default, Awesome Tools processes files entirely in your browser. Nothing is sent to our servers for conversion.
- Why is it slow the first time?
- ffmpeg WebAssembly is downloaded on demand. Subsequent runs may be faster due to caching.
- Why does conversion fail with “memory access out of bounds” or similar?
- Browser WebAssembly has a tight memory budget. Animated WebP re-encode can still OOM on very long or large sources. Try a shorter clip (e.g. under ~30s), a 1080p or smaller file, or transcode on desktop first.
- Why did my conversion fail?
- Large files, unusual codecs, or browser memory limits can cause failures. Try a smaller file or a different browser. See the limits on this page.
