Audio Converter

No. MP3 discards detail when it is made, and nothing can put that detail back. Converting it to WAV or FLAC gives you a bigger file that sounds the same; it is still worth doing when an editor or a submission portal only accepts WAV.

Podcasters turn WAV recordings into MP3 episodes, musicians send the WAV a mastering engineer or distributor asks for, and video editors convert music to 48 kHz for a timeline. When the job is to shorten a file rather than change its format, the audio cutter is the better fit; to change how it sounds, use the online audio editor or AI mastering.

192 kbps is a sensible default for listening and sharing. Choose 320 kbps when the source is lossless (WAV, FLAC or a studio export) and you want the best MP3 copy, and 128 kbps for spoken word or when file size matters most.

Size follows the bitrate you choose, not the source. A 96 kbps MP3 written at 192 kbps doubles in size and sounds the same, and WAV runs about 10 MB a stereo minute whatever went in. The file’s row says so when a compressed file comes out bigger. To keep a copy small, choose a bitrate at or below the source’s.

Anything your browser can decode. MP3, WAV, M4A/AAC and FLAC open in current Chrome, Edge, Firefox and Safari; OGG opens in Chrome, Edge and Firefox but may not in Safari. A file the browser cannot read reports an error and the rest of the batch continues.

No. The converter decodes and encodes inside the page: MP3 and FLAC with the same encoders as the online audio editor, OGG, M4A and AAC with the browser’s own. Closing the tab discards everything, and nothing is saved to your account.

44.1 kHz is the music standard and what streaming services and CDs use. Choose 48 kHz when the audio is going into a video project, which almost always runs at 48 kHz. WAV and FLAC also go to 88.2, 96, 176.4 and 192 kHz for a session or a delivery spec that asks for one; a file can then run up to 7.5 minutes at 96 kHz and 3.5 at 192 kHz. Raising the rate does not add detail that was not recorded.

For a podcast, a voice note or a single spoken track, mono halves the file size with no audible loss. Keep stereo for music: folding a stereo mix to mono can make wide effects and panned instruments thinner.

OGG, M4A and AAC are written by the encoder your browser ships, and not every browser has one for AAC or Opus. When it has none, the format stays in the list marked as not in this browser. Another browser may have it; MP3, WAV and FLAC work in every one.

Yes. Choose My music above the drop area and pick a song; it opens as the file its Download gives you, so it needs the same download right, and a plan without downloads lists the song with the reason. The conversion still runs in your browser.
