WAV to MP3 Converter

For music and archival storage — 320 kbps (maximum quality, indistinguishable from original). For podcasts and speech — 128-192 kbps. For background music and mobile devices — 128 kbps.

WAV takes about 10 MB per minute of audio. MP3 at 320 kbps — about 2.4 MB/min, at 192 kbps — 1.4 MB/min, at 128 kbps — 1 MB/min. Savings of 4-10x.

MP3 uses lossy compression — the algorithm removes audio details that the human ear hears less well. At 320 kbps losses are virtually undetectable. At 128 kbps experienced listeners may notice a difference on good equipment.

CBR (constant bitrate) — same quality throughout the track. VBR (variable bitrate) — algorithm allocates more data to complex sections. Our converter uses CBR for maximum compatibility.

MP3 supports ID3 tags (title, artist, album, cover). During conversion, basic WAV metadata is transferred to ID3 if present in the source file.

All of them. MP3 is the most universal audio format. Works on any smartphone, computer, car stereo, player, smart speaker. Supported by all streaming platforms and social networks.

No. When compressing to MP3, data is permanently removed. Reverse conversion creates a WAV file of the same quality as the MP3, just larger in size. Keep original WAVs if quality is critical.

The service accepts WAV files up to 100 MB. For uncompressed stereo 16-bit / 44.1 kHz, this is about 10 minutes of audio.

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.

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.

All three formats use lossy compression. AAC and OGG are more efficient than MP3 at low bitrates, but MP3 remains the most compatible format. For universal compatibility, choose MP3.

Depends on genre and listening conditions. For pop music in headphones or background listening — quite fine. For classical, jazz, or Hi-Fi system listening, better to choose 256-320 kbps.
