Why convert MP3 to WAV?

WAV is an uncompressed format ideal for audio editing. Unlike MP3, each WAV save doesn't add new compression artifacts. This is critical for studio work, track mixing, mastering, and sample creation.

Will sound quality improve after conversion?

No. Conversion doesn't restore frequencies lost during MP3 compression. However, WAV prevents further degradation: quality doesn't drop during editing and multiple saves.

Why is the WAV file much larger than MP3?

MP3 uses psychoacoustic compression, removing sounds the human ear hears less well. WAV stores all data without compression. Typical size ratio is 1:10 (MP3 320 kbps to WAV).

What are the output WAV file parameters?

The converter creates standard PCM WAV with parameters: 16-bit, 44100 Hz (CD quality), stereo. These parameters are compatible with all audio editors and DAWs.

Can I burn WAV to Audio CD?

Yes. WAV format at 16-bit / 44.1 kHz fully complies with the Red Book standard for audio CDs. You can burn the file directly to disc in any burning software.

What programs open WAV files?

WAV is supported by all operating systems and audio programs: Audacity, Adobe Audition, FL Studio, Ableton Live, Logic Pro, GarageBand, VLC, Windows Media Player, foobar2000.

Are ID3 tags preserved during conversion?

WAV format doesn't support ID3 tags (track name, artist, album). These metadata are lost during conversion. Save them separately if they're important.

What is the maximum file size for upload?

The service accepts MP3 files up to 100 MB. This is enough for 2-3 hours of audio at 320 kbps bitrate or 5-6 hours at 128 kbps.

Is it safe to upload copyrighted tracks?

Yes. All files are processed in an isolated environment and automatically deleted immediately after conversion. We don't store, listen to, or share your audio files with third parties.

Does the converter work on mobile?

Yes. The service is fully optimized for mobile devices. Works in Safari on iPhone, Chrome on Android. Upload files from the Files app or cloud storage.

Can I convert multiple files at once?

Currently the converter processes one file at a time. For batch conversion, upload files sequentially — each is processed in just seconds.

What's the difference between WAV and FLAC?

Both formats preserve audio without loss. WAV is uncompressed, takes more space, but opens everywhere. FLAC uses lossless compression (files are 2x smaller) but isn't supported by some legacy software.

Everything About MP3 to WAV Conversion

When you need WAV conversion

Convert MP3 to WAV before editing in audio editors (Audacity, Adobe Audition), creating samples for DAW, mixing multiple tracks, burning to Audio CD, or preparing audio for video editing. WAV doesn't add artifacts on multiple saves.

How MP3 compression works

MP3 uses a psychoacoustic model: the algorithm analyzes sound and removes frequencies humans hear less well — quiet sounds near loud ones, high overtones. At 320 kbps losses are minimal, at 128 kbps — noticeable on good speakers.

Why you can't improve MP3

MP3 is a format with irreversible losses. Removed frequencies cannot be restored by converting to WAV. The file will be larger, but not better quality. For archival storage, use original WAV/FLAC or high-bitrate MP3.

WAV for professional work

In studio production, WAV is the de facto standard. All DAWs (FL Studio, Ableton, Logic Pro) natively work with WAV. The format supports any bit depth (16/24/32-bit) and sample rate (44.1/48/96/192 kHz). Use WAV for exchanging projects between studios.

Optimal use scenarios

For playback and storage, keep MP3 — it saves space without noticeable quality loss. Convert to WAV only for editing, effects processing, or CD burning. After final processing, export back to MP3 for distribution.

How to convert MP3 to WAV

Upload your audio file

Drag and drop your MP3 file into the upload area or click to select. Supports files up to 100 MB — enough for an album or long podcast.

Wait for processing

The file is automatically decoded and saved as PCM WAV. Conversion happens on our server in just seconds.

Download the result

Click "Download WAV" and save the file to your device. Source and result are automatically deleted from the server after processing.

About File Formats

MP3 (MPEG-1 Audio Layer 3)

MP3 is the world's most widespread audio format. Developed in 1993 by the Fraunhofer Institute. Uses psychoacoustic compression to reduce file size by 10-12x with minimal quality loss.

• Universal compatibility with all devices
• ID3 tag support (title, artist, cover)
• Bitrate from 32 to 320 kbps
• Optimal for storing music collections

WAV (Waveform Audio)

WAV is an uncompressed audio format developed by Microsoft and IBM in 1991. Stores sound in PCM (Pulse-Code Modulation) format without any processing. The standard for the professional audio industry.

• Lossless quality — sound identical to original
• Support by all DAWs and audio editors
• Red Book standard for Audio CD
• High-resolution support (24/32-bit, up to 192 kHz)
