Frequently asked questions
Why convert WAV to MP3?
WAV stores audio uncompressed: a minute of 44.1 kHz stereo takes about 10 MB. The same minute as a 192 kbps MP3 is about 1.4 MB, and for most recordings you won't hear the difference.
Which bitrate should I pick?
192 kbps is a good choice for music and matches what streaming services use. 320 kbps is the maximum for MP3: slightly better quality, bigger file. For speech, podcasts and lectures, 128 kbps is plenty.
Will I lose quality?
MP3 is lossy: it drops details that are hard to hear. At 192–320 kbps the difference is usually inaudible. For archiving and editing, keep the WAV or choose FLAC, which compresses without loss.
What happens to multichannel audio?
MP3 is mono or stereo only, so recordings with more channels are mixed down to stereo.
Are the title and artist kept?
Yes. The tags of the original file — title, artist, album and others — are copied to the new file.
How many files can I convert at once?
Up to 100 files per batch. Download them one by one or all together in a single ZIP file.
Is it safe?
Yes. Only the converter itself is loaded from the site; your recordings are processed in your browser and never sent to a server.
