How to convert MP4, MOV, AVI, MKV, FLV, WEBM, and GIF

Drop your video into the upload area or click to browse. The tool auto-detects the source format — MOV from iPhone, AVI from older cameras, MKV from downloads, or WEBM from the web.

Choose your target format from the dropdown: MP4 for universal playback, MOV for Apple devices, WEBM for modern browsers, or GIF for short animated clips. Click "Convert video" and FFmpeg WASM processes the file locally.

Processed 100% on your device — no files are uploaded to any server. A live progress bar tracks encoding so you stay informed on large files. Your converted video downloads instantly when finished.

Frequently asked questions
