MP3 to WAV Converter
Get uncompressed WAV files from your MP3s for editing, burning or devices that cannot play MP3. Pick the bit depth, sample rate and channels the target expects, and convert several files at once.
- Files stay on your device
- No sign-up
- Free to use

Processing happens on your device; your audio is not uploaded.
How to use MP3 to WAV
- Drop one or more MP3 files onto the upload area.
- Choose the bit depth: 16-bit for compatibility, 24-bit or 32-bit float for editing.
- Choose the sample rate and channels, or keep them as in the MP3.
- Select Convert to WAV and download the files.

When to use MP3 to WAV
- Importing MP3s into editing software that prefers WAV.
- Burning audio CDs, which require 44.1 kHz 16-bit audio.
- Loading sounds into samplers, DJ hardware and older devices.
- Preparing audio for video editors working at 48 kHz.
- Supplying audio to systems such as phone menus that require WAV.
MP3 to WAV FAQ
Does converting to WAV improve quality?
No. The WAV contains exactly what the MP3 decoder produces; detail removed when the MP3 was made cannot be restored. WAV simply stores it without further loss.
Why is the WAV so much bigger?
WAV stores every sample uncompressed. A minute of 16-bit 44.1 kHz stereo audio is about 10 MB, roughly ten times a typical MP3.
Which bit depth should I use?
16-bit is enough for playback and CDs. Choose 24-bit or 32-bit float if you will process the audio heavily, which gives more headroom during editing.
What sample rate do CDs and videos use?
Audio CDs use 44.1 kHz. Video production usually uses 48 kHz. Keeping the original rate avoids resampling.
Are tags kept?
WAV files have limited and inconsistently supported tag formats, so metadata is not copied, for maximum compatibility.
When you need WAV instead of MP3
MP3 is designed for listening, not for editing. Each time an MP3 is opened in an editor, decoded, changed and saved again as MP3, another layer of compression loss is added. Converting to WAV once at the start of an editing session avoids that: all subsequent work happens on uncompressed audio, and only the final export is compressed.
Some hardware and software simply require uncompressed audio. CD burning software writes 16-bit 44.1 kHz PCM, phone systems and alarm panels often accept only WAV, and many samplers and DJ devices load WAV fastest. Choosing the expected bit depth and sample rate here avoids a second conversion later.
Bit depth sets the precision of each sample. 16 bits give a dynamic range of about 96 dB, enough for playback. 24-bit and 32-bit float provide headroom for processing such as gain changes and effects without rounding errors, which is why audio workstations use them internally.
Converting cannot recover information an MP3 discarded. If you have access to the original lossless recording, use that instead of converting an MP3 back to WAV.
