Make big WAV files small
WAV files keep every detail of the sound, which is why recorders, studios and some voice apps use them. The price is size: one minute of stereo WAV takes about 10 MB, while the same minute as MP3 is around 1.4 MB at 192 kbps. Converting to MP3 makes recordings easy to send and store.
When to keep WAV and when to convert
Keep the WAV (or save a FLAC copy, which is lossless and smaller) as your master if you will edit the recording again. Convert to MP3 for sharing on WhatsApp, email, websites and music players, where small files matter more than studio detail.
Choose the bitrate
Use 128 kbps for talks and podcasts, 192 kbps for music, and 320 kbps if you want the best MP3 quality. The export window shows the estimated size before you save.
Edit before saving
Trim the start and end, raise a quiet recording with Normalize, or remove background hum, then export the MP3 in one go. Everything runs in your browser; nothing is uploaded.

Questions about the WAV to MP3 converter
How much smaller will the MP3 be?
Usually 5 to 10 times smaller than the WAV, depending on the bitrate you choose.
Is there a size limit?
There is no fixed limit, but very large WAV files (over about 700 MB) may not open on phones because the work happens on the device.
Can I convert MP3 back to WAV?
Yes, but it will not bring back detail that MP3 removed. It only helps when a program needs a WAV file.
Should I choose FLAC instead?
Choose FLAC when you want a smaller file with no quality loss at all, for example to archive recordings.
