Frequently Asked Questions
Is my file uploaded to a server?
Files under 10 MB are converted entirely in your browser — nothing is sent to any server. Files above 10 MB are uploaded to our secure server, processed, and deleted immediately after you download.
Which quality should I pick?
192 kbps is the sweet spot — nearly indistinguishable from lossless for most people. Choose 128 kbps for smaller file size (podcasts, voice). Choose 320 kbps if you're a musician or audiophile.
Will quality be lost converting WAV to MP3?
WAV is lossless and MP3 is lossy, so some quality loss is inherent. However, at 192 kbps and above, the difference is virtually undetectable in normal listening.
What is the maximum file size?
The tool accepts WAV files up to 100 MB. Files under 10 MB are processed in-browser; larger files go to our server.
