How it works

  1. 01

    Choose a file for Audio Converter. It accepts MP4, MOV, WEBM, MKV, MP3, WAV, FLAC, OGG, M4A. Most files stay in this tab.

  2. 02

    Set the options on the workbench — preview, crop or timeline when this tool has one — then press Run.

  3. 03

    Download the result. It is also saved in your tray so the next tool can pick it up without another upload.

About this tool

MP3 encoding uses a WebAssembly build of LAME running in your browser; other targets use the encoders your browser ships. Keep the source sample rate unless a device requires otherwise, and choose 192 kbps or higher for music. Video files are accepted too — the audio track is converted and the picture discarded.

Questions

What can I open in Audio Converter?
Audio Converter accepts MP4, MOV, WEBM, MKV, MP3, WAV, FLAC, OGG, M4A. Older video containers such as AVI, WMV, FLV, MPEG and 3GP are decoded by the server encoder.
Does Audio Converter upload my file?
Most MP4, WebM, images and PDF stay in this tab. Instagram/TikTok crops, DVD, GIF, iPhone presets, stabilize, hard containers (AVI, WMV, HEVC) and a failed local encode go to the server encoder. The file is processed and discarded — we do not keep a copy.
How large can the file be?
Free: 500 MB and 8 exports a day. Plus (waitlist) raises the daily cap. A pasted public file URL is also accepted.
