How to convert MP3, M4A and OGG to WAV in your browser

A tool only accepts WAV, a recording came out as M4A, a clip needs to be smaller — audio format mismatches are common. This guide covers converting between formats locally, and which format to pick.

The fastest way

Open your file in the Audio Converter — MP3, M4A/AAC, OGG or FLAC — and export it as WAV, or as compressed WebM/Opus where your browser can encode it. The whole conversion happens on your device.

WAV vs compressed: which to choose

A quality reality check

Converting a lossy file (MP3, AAC) to WAV does not improve quality — the detail lost in the original compression is already gone. Convert to WAV for compatibility, not to "upgrade" audio. Starting from a lossless source (FLAC) preserves everything.

Trim before you convert

If you only need part of a clip, trim it first with the Audio Trimmer — a shorter clip means a much smaller WAV, which matters because uncompressed audio adds up fast.

A note on privacy

The Audio Converter decodes and re-encodes entirely in your browser — your audio is never uploaded, so voice memos and private recordings stay on your device.

Common questions

Which audio formats can I convert?

You can open an MP3, M4A/AAC, OGG or FLAC and export it as WAV, or as compressed WebM/Opus where your browser supports encoding it. WAV is uncompressed and works everywhere; Opus gives a much smaller file at similar quality where you need to keep the size down.

Should I convert to WAV or a compressed format?

Choose WAV when a tool or device needs an uncompressed, universally-supported file — editing software, some hardware, or when you'll process the audio further. Choose a compressed format (WebM/Opus) when file size matters, such as for sharing or web use. WAV files are large; converting a short clip to WAV can be tens of megabytes.

Does converting from MP3 to WAV improve quality?

No. MP3 is lossy, so the detail removed during MP3 compression is already gone — converting to WAV just stores the same audio in a larger, uncompressed container. It can't restore quality, only avoid losing more. Convert to WAV for compatibility, not for a quality boost.

Is my audio uploaded?

No. The conversion runs entirely in your browser using the Web Audio API — your file is decoded and re-encoded on your device and never leaves it, so even private recordings stay with you.
