Convert WAV to MP3 Audio Online
Uncompressed WAV audio recordings from microphones, digital audio workstations, or field recorders take up around 10 megabytes per minute of stereo audio. Converting WAV to MP3 cuts file size by up to 90%, making tracks easy to email, upload to podcast hosts, or store on mobile devices. Fileora encodes your audio locally using WebAssembly, letting you pick bitrates between 128 kbps and 320 kbps. Band recordings and voice memos remain entirely private.
