This free online mp3-to-wav converter is built for one job and does it well: pick a file, convert it, download it. For related jobs try our free file tools.
Quality note: WAV stores exact PCM audio with no compression. Files get much bigger than MP3 — that is normal and expected.

FAQ
Are my files uploaded to a server?
No. This MP3-to-WAV converter runs entirely in your browser: the file is read into memory on your device, converted locally, and downloaded back to you.
Is this MP3 to WAV converter free?
Yes. Converting MP3 to WAV with RayoPDF is free, with no watermarks and no account needed.
Will the WAV output lose quality?
No — and this matters: WAV preserves exactly what the MP3 contains, but it cannot recover quality the MP3 already lost. The file gets bigger, not better.
What if my file will not convert?
Check that it is a valid MP3 file (not renamed from another format), undamaged, and within the size limit shown under the drop box. Then try again with the original file.
