Audio converter (MP3 / WAV / M4A / FLAC)
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. ConvertMeow converts between MP3, WAV, M4A (AAC), FLAC and OGG locally in your browser. Lossless-to-lossless (WAV/FLAC) keeps full quality; converting to lossy formats like MP3/AAC lets you pick the bitrate. Nothing is uploaded, with no cap and no watermark.

How to use audio converter

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.
