How do I convert WAV to MP3?
Add your WAV files to the converter at the top of this page, choose a bitrate, and press Convert. The MP3 downloads as soon as it is ready. To keep only part of a track, cut it first with the
audio trimmer.
Why convert WAV to MP3?
File size. A 4-minute stereo WAV at
16-bit, 44.1 kHz is about 42 MB. The same track as a 320 kbps MP3 is about 9.6 MB, and at 128 kbps about 4 MB. That makes MP3 the practical format for email, messaging apps, phones, and sending demos, while the WAV stays your master.
Which MP3 bitrate should I use?
Use 320 kbps for music you send to listeners, labels, or DJs; it is the highest quality MP3 allows and hard to tell apart from the WAV on most systems. 192 kbps is a good middle ground for demos. 128 kbps is fine for speech, podcasts, and voice memos. For when each format makes sense, see
WAV vs MP3.
Does converting WAV to MP3 lose quality?
Yes, some. MP3 is a lossy format that removes detail the ear is least likely to notice in exchange for a much smaller file. At 320 kbps the difference is very hard to hear on most systems. Keep your original WAV as the master and treat the MP3 as a copy for sharing.
Can I convert M4A, FLAC, and OGG to MP3?
Yes. Any format your browser can decode works: WAV, M4A, AAC, FLAC, OGG, and AIFF, and you can mix them in one batch. Chrome and Edge decode the widest range; if a file fails in one browser, try another. For the reverse direction, use the
MP3 to WAV converter.
Can I convert several WAV files at once?
Yes, with a free Jukeblocks account. Drop in up to 20 files and press Convert once. Each file gets its own download link when it is ready, or use Download all to save them together.
Is there a file size or length limit?
Yes. Each file can be up to 200 MB and 30 minutes long, and you can convert up to 20 files at a time. That covers full songs, DJ mixes up to half an hour, and whole EPs in one batch. Longer files would use more memory than most browsers allow, especially on phones.
Can I add cover art and tags to the MP3?
Yes. Open the tags section before converting to add title, artist, album, year, genre, track number, BPM, comment, and a JPEG or PNG cover. In a batch, click a file in the list to edit its own tags, and use Copy to all files to set the artist, album, year, genre, comment and cover art on every file at once. They are written as ID3v2 tags, the format MP3 players, DJ software, and distributors read. To edit tags on an MP3 you already have, use the
MP3 tag editor.
Are my files uploaded to a server?
No. The conversion runs locally in your browser. Your audio is never sent to a server, stored, or logged, so it is safe for unreleased music.
Is this WAV to MP3 converter free?
Yes. Single files need no sign-up, and batch conversion only needs a free account. No watermark and no daily limit.
Does it work on iPhone and Android?
Yes, in mobile Safari and Chrome. On iPhone the MP3 is saved to the Files app; on Android it goes to Downloads. Long files take longer on phones because the encoding runs on the device.
