Convert any video to MP4, WebM, MOV, MKV, or animated GIF directly in your browser with ffmpeg.wasm. No uploads, no watermark, no account required.
Drag and drop or click to select the source file. Most common video formats are supported.
Pick MP4 for maximum compatibility, WebM for the web, MOV for Apple workflows, MKV for archival, or GIF for short loops.
Start the conversion and download the result. Everything happens locally in your browser.
Input: MP4, MOV, WebM, MKV, AVI, FLV, 3GP. Output: MP4 (H.264), WebM (VP9), MOV, MKV, and animated GIF.

Yes. Choose GIF as the output format. For best results, keep the clip short (under 10 seconds) and accept a lower frame rate.
Yes. MP4 and MOV output use AAC audio, WebM uses Opus, and MKV preserves the source audio when possible.
There is no hard limit, but because processing happens in memory in your browser, files over 1–2 GB may fail. For large files, consider the Pro plan.
