Convert OGG to MP3

Converts Ogg Vorbis to MP3 for hardware and software that does not support Ogg.

What to expect

Another lossy re-encode. Vorbis is generally the better codec, so this is a compatibility trade.

Why convert OGG without uploading

Most online converters take your file, send it to their servers, convert it there and hand back a download link. That means your document sits on someone else's disk, subject to their retention policy and their breaches. It also means you cannot use them offline, and cannot use them at all for anything confidential.

frogConvert does the conversion in the page itself, with FFmpeg compiled to WebAssembly. There is no upload step because there is no server. You can disconnect from the network and it still works.

About the formats

OGG

An open container, usually carrying Vorbis audio, created specifically to avoid MP3's patent licensing. Quality is better than MP3 at the same bitrate; support is narrower. More about OGG files.

MP3

The format that made digital music portable, using perceptual coding to throw away sound judged inaudible. Universally supported and comfortably outperformed by every codec designed since. More about MP3 files.

Common questions

Is my file uploaded when converting OGG to MP3?

No. The conversion runs entirely in your browser. The file never leaves your device, there is no server to upload to, and the page works offline once loaded.

Is OGG to MP3 conversion free?

Yes, with no account, no watermark and no file limit per day. frogConvert is open source and there is no server cost to recover, because your device does the work.

How large a file can I convert?

Up to 2 GB for a single file, 500 MB total per batch, and 300 files at once. The practical limit is your device's memory, since everything is processed locally.

What is lost converting OGG to MP3?

Another lossy re-encode. Vorbis is generally the better codec, so this is a compatibility trade.
