Your audio stays on your device. Encoding is done locally using the lamejs library in your browser.

MP3 compression can reduce file size by up to 90% compared to WAV — great for storage and sharing.

MP3 is the most widely supported audio format. Play on any device, share anywhere.

• Use 320 kbps for near-lossless quality — audiophiles can barely tell the difference from WAV.
• 128 kbps is sufficient for podcasts, voice recordings, and spoken-word content.
• 192 kbps offers the best balance between quality and file size for most music.
• A 50 MB WAV file typically compresses to 5-10 MB as MP3 at 192 kbps.
