Convert WAV to MP3 online, free
WAV files are studio-perfect and enormous — a 3-minute recording weighs 30MB, which chokes email attachments, messaging apps, and phone storage. MP3 at 192 kbps keeps audibly identical sound at a tenth of the size. The converter below opens pre-set to MP3: drop your WAV (recordings, exports, voice memos), choose bitrate, download a shareable file. All local, all free.

WAV workflow tips
Archive the WAV
WAV is your lossless master — convert copies for sharing, keep originals for future edits.
Voice memos love 128–192
Speech needs far less bitrate than music. A voice recording at 128 kbps sounds perfect and sips storage.
Too long to share?
If the MP3 is still huge, the audio is just long — trim it first with our MP3 trimmer.
