About converting WAV to MP3

Converting WAV to MP3 decodes the audio and re-encodes it to MP3 entirely in your browser. MP3 is small and universally playable; WAV is uncompressed and lossless.

Your audio never reaches a server. Converting an already-compressed file to a lossless format can't restore detail that was removed earlier.

This encodes your WAV to a 128 kbps MP3 — roughly a megabyte per minute, around a tenth of the WAV's size, in the one format every player, car stereo and messaging app accepts. Encoding runs entirely in your browser, so even big recordings never leave your machine.

Frequently asked questions

How do I convert WAV to MP3?

Add your WAV file above and press Convert. FileTinker decodes and re-encodes it to MP3 in your browser, then gives you the converted file to download — nothing is uploaded.

Is my audio uploaded to convert WAV to MP3?

No. The conversion runs entirely in your browser, so your audio never leaves your device and nothing is stored on a server.

Will converting change the audio quality?

WAV is uncompressed and lossless, while MP3 uses efficient compression at a high-quality bitrate. Converting an already-compressed file won't restore detail that was removed earlier.

Can I convert several files?

Convert them one after another — each runs locally and downloads instantly, with no queue, sign-up or file-size limit.

What bitrate does the MP3 come out at?

A fixed 128 kbps, which suits voice recordings, podcasts and everyday listening well. For critical music work keep the WAV as your master and treat the MP3 as the distribution copy.
