How it works
Add your OGG
Drop in a .ogg, .oga or .opus file. Voice notes saved from messaging apps are usually Opus and work here.
Choose the bitrate
128 kbps is plenty for a voice note. Use 192 kbps or more for music.
Download the MP3
One file that plays on every phone, player and computer.
Frequently asked questions
Why will my phone not play OGG files?
iPhones have never supported OGG in the built-in music app, and many car stereos and older players do not either. Opus — the codec inside most voice notes — is newer still and even less widely supported. MP3 is the one format that plays everywhere, which is the whole reason this page exists.
Can I convert a WhatsApp voice note?
Yes. Voice notes exported from messaging apps are usually Opus in an OGG container, sometimes with a .opus extension. Drop the file in as it is — the format is detected from the file itself, not from its name.
Which bitrate should I choose for speech?
128 kbps, and mono if it is a single voice. Speech carries far less information than music, so a higher bitrate adds size without adding anything you can hear. The mono option is on this page.
Will it sound worse?
Slightly. Opus and Vorbis are both efficient codecs and re-encoding to MP3 is a second lossy pass. For speech the difference is inaudible; for music, encode at 192 kbps or above.
What is the difference between OGG and Opus?
OGG is the container; Vorbis and Opus are two codecs that can sit inside it. Opus is the newer of the two and is what most voice notes, Discord recordings and modern game audio use. This tool reads both without being told which it is.
Is my file uploaded?
No. Voice notes are often private conversations; here the file is decoded and re-encoded entirely by your own browser and never leaves your device.
Good to know: Every pass through a lossy encoder throws a little more away, and it never comes back. Converting between MP3, AAC, OGG and Opus is one such pass. If you are going to edit the sound, convert to WAV first, do the work, and encode once at the end. Multi-channel OGG files are folded down to stereo, which is MP3's limit.
