Convert audio to MP3
Audio to MP3One page for every format that is not already an MP3: WAV, FLAC, M4A, AAC, OGG, Opus, WMA, AIFF and the rest, all converted in your browser.
MP3 to WAVTurn a compressed MP3 into an uncompressed WAV you can edit, master or hand to software that refuses anything else, at 16, 24 or 32-bit float.WAV to MP3Take an uncompressed recording and make it about a tenth of the size, at a bitrate you choose, without sending it anywhere.
M4A to MP3Voice memos, iTunes purchases and M4B audiobooks turned into a file that plays on anything, with the tags and the cover art still attached.
FLAC to MP3Make a lossless library portable: four to six times smaller, at up to 320 kbps, with the tags and the album art intact.
OGG to MP3Vorbis tracks, Opus voice messages from WhatsApp and Telegram, game audio, all into a format that opens without an argument.Edit audio
Trim AudioSee the waveform, drag the marks to where the sound actually starts, and cut to the sample, or cut the middle out and join what is left.
Change VolumeMake a file louder or quieter by a set amount, or normalise it, either to a peak level or to the perceived loudness that streaming services measure.
Fade AudioBring a track up from silence at the start and let it fall away at the end, with the length and the shape of each fade set separately.
Change Audio SpeedSpeed up a lecture or slow a solo down to learn it, and keep the voice a voice, because the pitch stays where it was.
Merge AudioJoin MP3, WAV, M4A and other audio files end to end, in the order you set. You get one WAV, and Audio to MP3 makes it an MP3.
Stereo to MonoMix both channels down to one, or throw one of them away and keep the other, which helps when a recording has a clean side and a ruined one.Record, ringtones, metadata
Audio from VideoPull the soundtrack out of MP4, MOV, MKV, AVI or WebM, often without re-encoding it at all, so nothing is lost on the way.
Ringtone MakerDrag the bar to the chorus, and get it back as an M4R the iPhone will accept, or an MP3 for Android, with the fades already in.
Edit Audio TagsFix the title, artist, album and cover art of a track, and get the file back with the audio untouched, byte for byte.
Voice RecorderRecord from your microphone in this tab and save it as MP3 or WAV. No app, no account, and the audio never leaves the machine.More audio tools: AAC, Opus, WMA, compress
AAC to MP3Raw AAC streams and AAC inside MP4 alike, including damaged captures, where a repair mode salvages what is still readable.
Compress AudioMake an audio file smaller by a preset, or name the size you need and let the bitrate be worked out for you.
OPUS to MP3The format your voice messages arrive in, turned into the one every player and transcription tool accepts.
WMA to MP3Rescue a Windows Media library that nothing outside Windows will open, in batches, with the tags kept.
