Frequently Asked Questions

Why should I convert WAV to MP3?
WAV files are uncompressed and take up significant space on your drive, making them tough to email or stream on the go. MP3 compression shrinks files to about a tenth of the size with virtually no audible difference, perfect for listening on your commute from LA to San Diego or storing thousands of tracks on your phone.
How much disk space will I save?
You can expect an 8-10x reduction in file size. For example, a rough mix export from a studio in Nashville that is 50MB as a WAV will compress to around 5MB as a 320kbps MP3. This saves gigabytes of space if you are digitizing a physical CD collection or a podcast archive.
Which MP3 bitrate is right for me?
For full music tracks like those charting in New York or Chicago, 320kbps provides near-lossless quality. If you are recording voice notes or a lecture, 128kbps is plenty. 192kbps is the sweet spot for podcasters wanting clear vocals without massive file sizes.
What is the maximum file size?
You can convert files up to 50MB. Since a minute of CD-quality stereo audio is about 10MB, this limit allows you to convert standard songs and voice memos easily. If you need to convert a 30-minute continuous concert recording, you might need to trim it first.
Is my data private and secure?
100% yes. Because the tool runs directly in your browser tab, nothing gets uploaded to the cloud. You could convert a file while using public Wi-Fi at a coffee shop in Seattle, and the audio would never leave your device.
