Audio to WAV Converter
Convert MP3, OGG, M4A, and WebM audio to WAV in bulk, entirely inside your browser.
Why convert audio to WAV?
WAV is an uncompressed, universally supported audio format that opens cleanly in virtually every audio editor, video editor, and operating system, without relying on a codec. This tool decodes your MP3, OGG, M4A, or WebM file using the browser's Web Audio API and re-encodes it as WAV — no server-side conversion involved.

Features & benefits
Why this runs entirely in your browser
Audio files can be personal recordings or unreleased work, so nothing is uploaded to a server. Decoding and re-encoding both happen locally using the Web Audio API running in the tab.
Common uses
Preparing audio for an editor that only accepts WAV, converting a voice memo for further processing, or getting a lossless-container copy of a compressed file before editing.
Frequently asked questions
A few things people usually want to know before trusting the numbers.
WAV is uncompressed, so it's normal for it to be noticeably larger than a compressed MP3 or OGG source — the trade-off is universal compatibility and no further quality loss.
No additional quality is lost during conversion itself — the original compressed file already set the quality ceiling, and WAV simply stores those decoded samples losslessly from that point on.
Some formats or codecs aren't supported by every browser's built-in decoder. Try opening the file in another player to confirm it isn't corrupted, or try a different browser.
Yes, up to 20 at a time. Each converts automatically, and "Download all" zips every finished WAV file together.
No. All conversion happens locally in your browser. Nothing uploaded here is sent to a server, stored, or shared.
