Quick answer
How do you convert MP3 to WAV?
To convert MP3 to WAV, choose your MP3 in the tool above, pick 44.1 or 48 kHz, then press Download WAV. Your browser does the work, so the file is never uploaded, and it's free with no account. It takes files up to 60 MB, about an hour of 128 kbps MP3, and saves a 16-bit WAV. The WAV won't sound better than the MP3. It's just easier for editors and other software to use.

- Video project
- 48 kHz, the usual rate for video.
- Sampler
- Check its manual, then pick the rate it lists.
- Upload form
- Use the rate it asks for, or 44.1 kHz if it doesn't say.

Tips
Good to know before you convert
A few things that save a second try.
Have the original recording? Use that instead, because it holds more detail than the MP3.
Keep your MP3. It's much smaller, and you can make the WAV again at any time.
Check the WAV size in the tool before downloading a long file.
Only need one section? The audio trimmer opens MP3s and saves that part as a WAV.
Only convert audio you have the right to use.
FAQ
MP3 to WAV Converter questions
10 questions
How do I convert MP3 to WAV for free?
Choose your MP3 in the converter at the top of this page, pick a sample rate, then press Download WAV. It's free, with no account and no watermark.
Link to this answerIs my MP3 uploaded anywhere?
No. Your browser decodes the file and builds the WAV on your device, so the audio never reaches our servers.
Link to this answerDoes converting MP3 to WAV improve the sound quality?
No. MP3 is lossy, so the detail removed when it was made is gone for good. The WAV holds exactly what the MP3 could play, in a bigger file.
Link to this answerDo I lose any quality going from MP3 to WAV?
Almost none. The WAV isn't compressed again. It's stored as 16-bit, and it's resampled if you choose a rate that differs from the MP3's. Any peaks that decode above full scale are clipped at the limit.
Link to this answerWhy would I want a WAV if it doesn't sound better?
Mainly because some software asks for it. Many samplers, editors, CD burning apps and upload forms prefer WAV. It's also a better working format: edit a WAV and you only compress once at the end, instead of adding another round of MP3 loss.
Link to this answerHow big will my WAV be?
A stereo WAV at 44.1 kHz takes about 10.6 MB per minute, or about 11.5 MB at 48 kHz. The MP3's bitrate doesn't change that. In our test, three minutes made a 31.8 MB WAV from both a 128 kbps and a 320 kbps MP3.
Link to this answerShould I choose 44.1 or 48 kHz?
Use 44.1 kHz for music and audio CDs, and 48 kHz for video. Neither adds detail, so go with whatever your project or app asks for.
Link to this answerCan I burn the WAV to an audio CD?
Yes, as long as your burning software accepts WAV. Pick 44.1 kHz, since CD audio is 16-bit at 44.1 kHz. A CD still sounds like the MP3 it came from.
Link to this answerCan I convert several MP3s at once?
No, this tool handles one file at a time. For a big batch, a desktop tool such as ffmpeg will be quicker.
Link to this answerCan I convert a WAV back to MP3 here?
Not with this tool, which always saves a WAV. Our M4A to MP3 converter also opens WAV files up to 60 MB and saves them as MP3s, on your device.

MP3 to WAV Converter, explained
What works, what to avoid, and how the pieces fit.
On this page
What changes when an MP3 becomes a WAV
MP3 shrinks audio by throwing away detail people are less likely to notice [1]. To play it, software decodes it back to plain samples. A WAV normally stores those plain samples as uncompressed PCM [2], so converting really means decoding the MP3 and saving the result.
That's why the WAV can't sound better. It's an exact record of what the MP3 decodes to, not a copy of the original recording. What you gain is a file that nearly any audio software can open without decoding it first.
How big the WAV gets next to your MP3
WAV size depends on the length, sample rate and channels, not on the MP3's bitrate. So a low-bitrate MP3 grows the most. These figures are for a stereo WAV at 44.1 kHz:
- 128 kbps MP3 — about 1 MB per minute, so the WAV is around 11 times bigger.
- 192 kbps MP3 — about 1.4 MB per minute, so the WAV is around 7 times bigger.
- 320 kbps MP3 — about 2.4 MB per minute, so the WAV is around 4.4 times bigger.
- Mono MP3 — the WAV stays mono, at about 5.3 MB per minute.
When WAV really does help
If you plan to edit, there's a good reason to convert first. Each time you save to MP3 again, it throws away a little more. Work in WAV and you only compress once, at the very end.
- Editing and mixing — cut, layer and process without new MP3 loss at each save.
- Samplers and older hardware — many read WAV but not MP3, so check the manual for the rate it needs.
- Audio CDs — CD audio is 16-bit at 44.1 kHz [3], which is what this tool saves at that setting.
- Upload forms — when a site asks for WAV, this gets you past the form. It won't pass a quality check that looks for a lossless source.
How long it takes
We timed the converter's decode and WAV steps on 5 November 2026 in Edge on one Windows desktop, using generated test tones. Your times will differ, and we haven't measured phones, Safari, Firefox or Chrome.
- Three-minute MP3, 2.9 MB at 128 kbps — opened in about 0.2 seconds. It made a 31.8 MB WAV at 44.1 kHz or a 34.6 MB WAV at 48 kHz.
- One-hour MP3, 57.6 MB at 128 kbps — opened in 4.6 seconds and exported in 1.3 seconds, making a 635 MB WAV.
- 25-minute MP3, 60 MB at 320 kbps — opened in 2.3 seconds and made a 264.6 MB WAV.
- Length — every test file came out exactly as long as it went in, with no added silence at the start.
When a browser tool isn't the right fit
This converter suits one file you want to keep private. Use something else in these cases:
- Files over 60 MB or big batches — ffmpeg is free and runs on your own computer: ffmpeg -i input.mp3 output.wav
- Phone systems that want 8 kHz audio — this tool only saves 44.1 or 48 kHz, so use a desktop tool such as ffmpeg.
- You want part of the file — the audio trimmer saves just the section you keep.
- Your audio is an M4A — the M4A to WAV page covers what's different about that format.
