How to convert a video

Convert video formats entirely in your browser using ffmpeg.wasm — no upload, your file never leaves your device.

Steps

1. Choose a video.
2. Pick an output format:
   • MP4 / WebM — re-encode to a different container/codec.
   • GIF — turn a clip into an animated GIF (downscaled to 480px, 10fps).
   • MP3 — extract just the audio track.
3. Convert & download. The first run loads the video engine (a one-time wasm download); progress is shown as it processes.

Note: in-browser video processing is memory- and CPU-intensive — best for short clips. Large files take time.
