How to use the Video & Audio Converter

Upload a video or audio file (MP4, WebM, MOV, MP3, WAV, M4A and more).
Pick the output format — choose MP3 or WAV to extract just the audio from a video.
Optionally lower the resolution to shrink file size, or trim to a start/end time.
Click Convert & Download. The first conversion loads a ~30 MB engine once per session — after that, conversions are quick.

🔒 Your file is processed entirely on your device using WebAssembly. Nothing is ever uploaded to a server. On mobile, we recommend files under ~150 MB and a Wi-Fi connection for the first use.
