- The sample rate is your device's playback rate, usually 44.1 or 48 kHz.
- Converting an MP3 to WAV makes it easy to edit, but it cannot bring back detail the MP3 removed.
- The file is named after your audio with _converted.wav at the end.
About MP3 to WAV Converter
Our free MP3 to WAV converter transforms compressed audio files into uncompressed WAV, the format most audio editors, CD burning software and broadcast systems expect. WAV does not restore detail the MP3 already discarded, but it stops further loss on each edit and re-save. This online audio format converter gives you a WAV file ready to drop into an editor.
This audio converter tool turns your MP3 (or another audio file) into a 16-bit PCM WAV file. A progress indicator shows that the conversion is running, and the built-in audio player lets you preview the result before downloading.
Your audio files stay on your device and are never uploaded to any server, making this a privacy-first format converter that keeps your music, recordings, and creative work completely secure. The tool supports input files up to 200MB, handling everything from short clips to full-length albums.

How to Convert MP3 to WAV
- Upload your audio file: Click "Choose Audio File" to select an MP3 or other audio file from your device (up to 200MB).
- Review file details: The tool displays the file name, size, and format type so you can verify the correct file is selected.
- Start conversion: Click "Convert to WAV" to begin the conversion process. A progress indicator shows while the file converts.
- Compare file sizes: After conversion, review the side-by-side comparison of original and converted file sizes to understand the difference between compressed and uncompressed formats.
- Preview the result: Use the built-in audio player with playback controls to listen to the converted WAV file and verify quality.
- Download your WAV file: Click "Download WAV" to save the converted file to your device, or click "Convert Another" to process a new file.
Use Cases
- Music production: Convert MP3 reference tracks or samples to WAV for use in DAWs like Ableton Live, FL Studio, Logic Pro, or Pro Tools.
- CD mastering: Prepare audio tracks in uncompressed WAV format for CD burning and mastering workflows; the WAV uses your device's playback rate (usually 44.1 or 48 kHz), so resample to 44.1 kHz if your burning software needs it.
- Audio editing: Convert compressed files to WAV before editing in professional audio editors to avoid quality loss from repeated re-encoding.
- Broadcasting: Transform compressed audio to uncompressed WAV for broadcast systems that require lossless input formats.
- Sound design: Convert audio samples and sound effects to WAV format for compatibility with professional sound design tools and game engines.
- Archival storage: Keep audio recordings in uncompressed WAV format for long-term archival; the WAV holds what the source contains and cannot restore detail removed by MP3 compression.
- Hardware compatibility: Create WAV files for older audio hardware, samplers, or synthesizers that only accept uncompressed audio input.
Frequently Asked Questions
Does converting MP3 to WAV improve audio quality?
Converting MP3 to WAV creates an uncompressed version of the audio, but it cannot restore quality that was lost during the original MP3 compression. The WAV file holds the same audio as the MP3 in an uncompressed format, at your device's playback rate (usually 44.1 or 48 kHz).
Why is the WAV file so much larger?
WAV is an uncompressed format that stores every audio sample as raw data. An MP3 typically compresses audio to about 10% of its uncompressed size, so the WAV version will be approximately 10 times larger.
What audio formats can I convert?
While the tool is named "MP3 to WAV," it accepts most audio files, including MP3, AAC, OGG, M4A, FLAC, and WebM. All inputs are converted to standard 16-bit PCM WAV.
Can I use this on mobile?
Yes, the converter works on mobile browsers. Simply open it on your phone, select a file, and convert. The process is the same as on desktop.
Tips & Best Practices
- Use high-quality source files: The WAV output will only be as good as the source. Start with the highest quality MP3 (320 kbps) available for the best results.
- Plan for larger file sizes: WAV files are significantly larger than MP3. Ensure you have enough storage space before converting large collections.
- Preview before downloading: Use the built-in audio player to verify the conversion sounds correct before saving the file to your device.
- Convert for editing, not storage: If you need to edit audio, convert to WAV first. For long-term storage of compressed originals, keep the MP3 and the WAV as separate copies.
- Check the file comparison: Review the original vs. converted file size display to understand how much space the WAV file will require.
- Use for DAW imports: Many digital audio workstations handle WAV files more efficiently than compressed formats. Converting before importing can improve editing performance.
