WAV to MP3 Converter
WAV is uncompressed, which makes it perfect for editing and terrible for sharing — a ten-minute recording easily passes 100 MB. MP3 brings that down to a few megabytes while staying perfectly listenable.

WAV to MP3 — frequently asked questions
How much smaller will the MP3 be?
At 128 kbps, roughly one tenth the size of a CD-quality WAV. A 100 MB recording typically lands around 10 MB.
Are my files uploaded to a server?
No. AllConverter runs the whole conversion inside your browser tab using WebAssembly and the Canvas API. Your file never travels over the network, which you can confirm by watching your browser's Network tab while you convert.
