Why convert WAV to MP3?
WAV files from recorders, DAWs and audio CDs are uncompressed and take about 10 MB per minute. As MP3 the same audio takes around a seventh of the space, which makes it easy to send, upload and store on a phone.
When to keep the WAV
Keep the WAV as your master for editing, mixing and mastering: every MP3 encode removes some detail.
Tips for the best result
- The MP3 is encoded at high-quality variable bitrate (around 190 kbps), transparent for most listeners.
- Stereo and mono recordings keep their channels.
- Trim silence before converting for an even smaller file.
Common problems and fixes
- The MP3 is too big for a form.
- Very long recordings are still large. Split the recording into parts, or use a speech-focused format.
- The sound clips or distorts.
- If the WAV is recorded too loud, the MP3 shows it too. Lower the level in an editor before converting.
MP3 – MPEG Audio Layer III
MP3 is the most widely supported lossy audio format. It makes music files small enough to share and plays on virtually every device.

Frequently asked questions
Is MP3 good enough for music?
At the quality used here most people cannot tell MP3 from the WAV on normal headphones and speakers.
How much smaller is the MP3?
Usually around seven times smaller than CD-quality WAV.
How much smaller is the MP3 than the WAV?
Usually around 7 to 8 times smaller, because WAV stores uncompressed audio and MP3 uses high-quality compression.
How do I convert WAV to MP3?
Click Select File or drop your WAV file onto the upload box. The converted MP3 appears in the list below with a download button. You can add many files at once and download them together as a ZIP.
Is it really free?
Yes. There is no sign-up and no watermark. To keep the service available for everyone there is a 95MB limit per file and a cap on how many files one connection can process in a short period.
Are my files stored?
Your upload is used only to make the converted file. Images are processed in memory; other files are written to a private temporary folder that is deleted as soon as the conversion finishes. Nothing is kept after the result has been sent back.
Will quality drop?
For images, a little, by design: the image is re-encoded at the Quality you choose (default 75%). Audio and video are re-encoded with high-quality settings; documents keep their text and layout as far as the target format allows. Converting never restores detail that is already missing from the original.
How this works: your file is uploaded over HTTPS and converted on this server with open-source engines (libvips for images, FFmpeg for audio and video, LibreOffice and Pandoc for documents, Calibre for ebooks, Ghostscript and Inkscape for PDF and vector files). Images are processed in memory; other files use a private temporary folder that is deleted as soon as the conversion finishes.
