How to Convert MP3 to WAV?

Decompress your MP3 files into high-quality WAV format for burning CDs or editing in professional software.

1

Upload MP3

Select your MP3 files from your computer or drag and drop them here. Batch conversion is supported.

2

Set Quality

Choose your desired sample rate (usually 44.1kHz for CD quality) and start the conversion.

3

Download WAV

Get your uncompressed WAV files instantly. Perfect for archiving or further editing.

Pro Tip: Editing Ready

Use WAV files when importing audio into video editors like Premiere Pro or Final Cut to ensure smoother playback and seeking.

Engineering Philosophy

Preparing for
Lossless Editing.

Converting MP3 to WAV doesn't magically add missing frequencies back to the audio, but it performs a critical function: decompression.

Our engine decodes the MP3 stream into raw PCM (Pulse Code Modulation) data. This is the exact digital representation of the analog sound wave. We ensure this decoding process is bit-perfect, ensuring no additional noise or artifacts are introduced during the format change.

This "inflated" WAV file is now ready for editing in any DAW (Digital Audio Workstation) without the CPU overhead of constantly decoding MP3s, and without the risk of "generation loss" if you save it again.

Crafted by Audio Engineers

Secure Wipe

Files are deleted immediately after your session. Your audio is private.

PCM 16-bit

We decode to standard CD-quality WAV 16-bit/44.1kHz by default.

Instant Decoding

Optimized for fast browser-based upload

Why Convert Back to WAV?

MP3 is great for listening because it's small, but it's not ideal for editing. Every time you edit and save an MP3, it gets compressed again, losing more quality (generation loss).

WAV (Waveform Audio File Format) is uncompressed. By converting your MP3s to WAV before you start editing, mixing, or burning to a CD, you stop the quality loss cycle. It ensures that your editing software works with the raw audio data, providing better performance and stability.

The RiseConvert Advantage

  • Pure Decoding: We use industry-standard decoders to ensure no errors when inflating the MP3 back to PCM audio.
  • Privacy Focused: We don't listen to your audio. It's processed and wiped.
  • Universal Compatibility: The WAV files we generate work on Windows, Mac, Linux, and in every audio software known to man.

Audio Definitions

PCM

Pulse Code Modulation. The standard method for digitally representing analog audio signals in WAV files.

Sample Rate

The number of audio samples carried per second, measured in Hz or kHz (e.g., 44.1kHz).

Bit Depth

The number of bits of information in each sample. CD audio is 16-bit.

Generation Loss

The loss of quality between subsequent copies or transcodes of data. WAV prevents this.

Common Questions

Will the audio sound better?

No. Converting a low-quality MP3 to WAV cannot add detail that isn't there. It just prevents it from getting worse during editing.

Best uses for WAV

Use WAV for master files, CD burning, and as intermediate files in video/audio production projects.

Frequently Asked Questions

Is converting MP3 to WAV lossless?
The conversion process itself is lossless (decoding), but it cannot recover quality lost when the MP3 was originally created. The resulting WAV will sound identical to the MP3, not better.
Why is the WAV file so big?
WAV is uncompressed data. An MP3 compresses audio by about 10x to 12x. When you convert back to WAV, you are unzipping that data back to its full size, usually around 10MB per minute.
What is the best sample rate to choose?
44.1kHz is the standard for music CDs and most digital audio. 48kHz is standard for video production. Choose the one that matches your final destination.
Is this tool free?
Yes, it is completely free to use online without installing any software.
Can I use this on my phone?
Absolutely. RiseConvert works directly in your mobile browser (Chrome, Safari, etc.) on iOS and Android.
