Audio converter (MP3 / WAV / M4A / FLAC)

Convert between MP3, WAV, M4A, FLAC and OGG — lossless-to-lossless when you need it.

Your recorder exported WAV but you need a small MP3 to send, your lossless album is FLAC but the car only plays MP3, your editor wants WAV source — the wrong audio format just won't work.

How to use audio converter

  1. 1Drop in or select an audio file (MP3 / WAV / M4A / FLAC / OGG).
  2. 2Choose a target format; when going to MP3 / AAC, set a bitrate (e.g. 192 / 320kbps).
  3. 3Click Convert. ConvertMeow decodes then re-encodes to the target format in the browser.
  4. 4Download the result. The audio was never uploaded.

Why use ConvertMeow's Audio converter?

  • Lossless stays lossless: WAV ↔ FLAC keeps every bit, and FLAC also shrinks a lossless file to about half the size — great for archiving.
  • You pick the bitrate: when going to MP3 / AAC you choose the trade-off between size and quality instead of being locked to a default.
  • Audio stays on your machine: interviews, demos and unreleased recordings are converted in your browser, never sent to a server.

Frequently asked questions

No. Information MP3 threw away during compression can't be recovered by moving it into a lossless container — you just get a bigger file holding the same lossy audio. Lossless conversion only helps when the source itself is lossless (like WAV/FLAC).

Both are lossless and sound identical. WAV is uncompressed, larger, and the most compatible (best for editing/sampling). FLAC is losslessly compressed, about half the size, and ideal for archiving and hi-fi playback. Choose WAV to keep editing, FLAC to store or carry around.

The current version handles one file at a time to keep each conversion solid. For multiple files, convert them one by one, or export each separately and process them together later.
