Convert audio in your browser
Powered by FFmpeg compiled to WebAssembly, these converters run entirely on your device. Compress recordings with WAV to MP3, go lossless with MP3 to WAV, convert Apple audio with M4A to MP3, or extract sound with MP4 to MP3. You can also trim audio and make ringtones.
Every tool here runs entirely in your browser, so your files never leave your device — conversions are instant, private and free.
