FAQ
Is the audio quality the same as the original?
MP3 is a lossy format. 192 kbps or 256 kbps provides near-transparent quality for most content. 320 kbps is the maximum MP3 bitrate.
Can I convert MOV or WebM?
Yes. Any video format supported by the browser can be converted.
Are my files uploaded?
No. The conversion runs in your browser using FFmpeg WebAssembly. Your files never leave your device.
Is there a file size limit?
Up to 2 GB. The first run downloads the FFmpeg engine (~30 MB, cached afterwards).
