About this tool
OGG (Vorbis or Opus) audio from games, Linux apps, Telegram voice messages, and some recorders often will not play on iPhones, in cars, or in editing software. MP3 fixes that instantly.
About the formats: OGG files hold Vorbis or Opus audio, open formats used by games, Linux software, and some voice recorders. Quality per megabyte is excellent, but device support outside the desktop is spotty. MP3 is the universal lossy audio format. Practically every device, car stereo, and app made in the last 25 years plays it, and at 192-320 kbps it is indistinguishable from the original for most listeners.
Everything happens inside your browser. Your file is never uploaded to a server: the conversion runs on your own device using WebAssembly, and the result is downloaded straight from memory. Close the tab and nothing is left behind.
How to use it
- Drop your OGG files into the box above, or click to browse. Nothing is uploaded.
- Adjust the options if you want; the defaults suit most files.
- Click Convert to MP3 and wait a moment.
- Download the results individually or all at once as a ZIP.
Frequently asked questions
Are Opus files supported?
Yes. Both Vorbis and Opus audio in .ogg, .oga, or .opus files convert to MP3.
Is this really free?
Yes. The site is supported by ads, and there are no limits on how many files you convert.
Are my files uploaded anywhere?
No. The converter runs entirely in your browser. Files stay on your device, which also makes it faster than upload-based converters for anything larger than a few megabytes.
Is there a file size limit?
The only limit is your device's memory. Images and audio of any normal size are fine; for video, files under about 500 MB work well on most laptops and phones.
Which browsers are supported?
Current versions of Chrome, Edge, Firefox, and Safari on desktop and mobile. Very old browsers without WebAssembly support will not work.
