Lossy and lossless
Convert to compact MP3/M4A/OGG or lossless WAV/FLAC, whatever you need.
Private by design
In-browser FFmpeg means your audio is never uploaded.
Free, no watermark
No account, no trial limits and a clean output file.
Compress voice memos for email
Phone voice memos and meeting recordings often arrive as bulky M4A or WAV files that bounce off email attachment limits. Drop the recording here and export it to MP3 at 192kbps to cut the size dramatically while keeping speech perfectly clear. The whole conversion runs in your browser, so a confidential interview or lecture never leaves your device.
Make audiophile FLAC playable in the car
Lossless FLAC and high-res WAV libraries sound great at home but many car stereos, Bluetooth speakers and older MP3 players refuse to read them. Convert those tracks to MP3 or M4A here for a file that plays on practically any hardware. You trade a sliver of fidelity for universal playback, and nothing uploads to a server during the process.
Get WAV stems ready for a DAW
Most editors and DAWs like Audacity, Audition or Ableton work best with uncompressed PCM. If a download or export arrived as MP3, OGG or M4A, convert it to WAV here so you can import clean audio for mixing without fighting codec support. It will not restore detail lossy compression already removed, but it stops any further generation loss while you edit.
