How do I check the WAV before I save it?
To convert MP3 to WAV for free, choose the MP3 above, keep WAV selected, and select Convert to WAV. Your browser writes an uncompressed WAV in seconds, with no upload. Play the WAV on this page before you download it.
Play it here first
A player appears under the download button. Skip to the start, the middle, and the end to check the whole file came through.
Expect the same sound, in a bigger file
A WAV made from an MP3 sounds the same as the MP3. It is larger because nothing is compressed, not because detail was added.
Why convert MP3 to WAV?
An MP3 plays everywhere, but editors, samplers, and some upload forms want WAV. Converting MP3 to WAV gives them a file they accept without a second lossy step.
Your editor asks for WAV
Some DAWs, video editors, and radio or podcast hosts only take WAV. Converting first saves a failed import.
You plan several edits
Each MP3 export loses a little more. Edit a WAV, then export one final MP3 at the end.
A sampler or game engine needs PCM
Hardware samplers, ringtone tools, and many game engines read uncompressed PCM WAV only.
The MP3 has a hum or hiss to clean
Noise removal works on any format, and a WAV keeps the cleaned result lossless until you choose the final format.
Remove background noise from audioDoes converting MP3 to WAV improve quality?
No. MP3 compression removes sound for good, and a WAV cannot bring it back. Converting MP3 to WAV stops further loss when you edit, which is the real reason to do it.
| Compared on | MP3 | WAV from that MP3 |
|---|---|---|
| Sound | What the encoder kept | Exactly the same, decoded |
| Size for 10 minutes, stereo | About 14 MB at 192 kbps | About 100 MB at 44.1 kHz |
| Loses quality when you edit and save again | Yes, each export re-encodes | No, until you export a lossy file |
| Best for | Listening and sharing | Editing, mixing, samplers, and noise removal |
Why use EraseNoise instead of an upload site?
It does one job: decode the MP3 and hand back a standard WAV, with nothing added.
Nothing is uploaded
The MP3 is read and the WAV is written by your browser. A private recording stays on your device.
A plain WAV every editor opens
When you convert MP3 to WAV here, the output is uncompressed PCM WAV at the MP3’s own sample rate, so Premiere, DaVinci Resolve, Audacity, and GarageBand open it as it is.
Free with no account
There is no sign-up, no daily cap, and no audio watermark. The work runs on your device, so it costs nothing to offer.
Other formats too
M4A, AAC, OGG, Opus, and FLAC convert to WAV the same way, and you can switch the output to MP3 or M4A.
Why is it faster than uploading to a converter?
There is no upload and no queue. When you convert MP3 to WAV here, a typical song takes a few seconds, about as long as decoding it.
No upload, no download wait
Online tools that convert MP3 to WAV send a 100 MB WAV back over the network. Here it is written straight to your device.
Works on a phone
To convert MP3 to WAV on an iPhone or Android, open the page in Safari or Chrome, pick the MP3 from Files, and save the WAV back to Files.
No editor to open
You do not need a project or an export dialog to change one file’s format.
Which files can I convert to WAV?
Convert MP3 to WAV, or any common audio format, for files up to 2 GB and up to 60 minutes long.
MP3, M4A, AAC, OGG, Opus, or FLAC
Songs, podcasts, voice memos, and exports from most apps. Each becomes a WAV with the same sample rate and channels.
Up to 60 minutes
The WAV is built in your browser’s memory, so one file can be up to an hour. Ten minutes of stereo WAV is about 100 MB.
A video instead
To get WAV out of an MP4, MOV, or WebM, use the video to WAV page, which takes video files.
Files you are allowed to use
This page converts files already on your device. It does not download audio from websites.

Does converting MP3 to WAV improve quality?
No. The WAV sounds exactly like the MP3. Converting MP3 to WAV only stops further loss while you edit, and gives apps that need WAV a file they accept.
Why is the WAV so much bigger than the MP3?
WAV stores every sample uncompressed. Ten minutes of stereo at 44.1 kHz is about 100 MB, while a 192 kbps MP3 of the same length is about 14 MB.
Is my file uploaded?
No. The MP3 is decoded and the WAV is written in your browser. Nothing is sent to EraseNoise or anyone else.
What sample rate is the WAV?
The same as the MP3, usually 44.1 or 48 kHz, with the same number of channels. Nothing is resampled.
Can I convert a long MP3 to WAV?
Yes, up to 60 minutes per file. The WAV is built in memory, so longer files would not fit in most browsers. For longer audio, keep it as MP3 or M4A.
