Frequently asked questions
Does converting MP3 to WAV reduce audio quality?
The output format is uncompressed, so the file will be significantly larger. Note that converting back to lossless does not restore quality already lost in the source — it only preserves what is currently there.
Are my MP3 files uploaded to a server?
No. The MP3 → WAV conversion runs entirely in your browser, locally. Open the Network tab in your browser dev tools to verify it for yourself: no outgoing request is made during the conversion.
Is there a file size limit for MP3 files?
No limit imposed by convert-buddy. The only constraint is the memory available in your browser — on a modern desktop, multi-gigabyte MP3 files work fine.
