About this tool

Need a GIF for a README, a Slack reaction, a tweet? Online converters are free until your video has anything sensitive in it (it doesn't matter that they "promise" not to keep it — you can't audit them). This tool runs a real FFmpeg compiled to WebAssembly inside your browser. The video is read from your disk into memory, processed locally, and the GIF is downloaded — never uploaded. Best results: ≤ 10 seconds source clip, 480px wide, 12-15 fps. Larger sources still work but eat RAM.

Privacy

Processing happens in your browser whenever the tool can run locally. Your source files are not uploaded to PixWarp servers.

Frequently asked questions

What's the file size limit?
Hard limit is your browser's memory. Practical limit: a 10-second 1080p MP4 (~20 MB) is fine. Bigger may stall.
Why is the GIF bigger than the MP4?
GIFs use a 256-color palette and lossless compression — they will be larger than equivalent MP4 / WebM. Trim the clip, lower fps, or reduce width to shrink.
Does this upload my video?
No. FFmpeg runs as WebAssembly inside the page. The video bytes never leave your computer.
Why does the first conversion take a few seconds longer?
Loading the FFmpeg WebAssembly core (~30 MB) on first use. After that it's cached.
