What is an OGG file?

OGG is an open, royalty-free container, most commonly carrying Vorbis-encoded audio. It was built as the free-software answer to MP3 and delivers comparable or better quality at the same bitrate.

OGG shows up in games, open-source software and some Android recording apps. Older iPhones famously could not play it, which is the usual reason people need to convert one.

Why MP3?

MP3 (MPEG-1 Audio Layer III) is the format that made digital music portable in the late 1990s, and it remains the most universally supported audio format ever made. It compresses audio by discarding detail the ear is least likely to miss, at bitrates typically between 128 and 320 kbps.

Convert to MP3 when compatibility matters more than anything else, sending audio to someone whose device you don't know, uploading where only MP3 is accepted, or shrinking a large recording down to an email-friendly size. OGG's practical weakness is device support: Apple devices only gained reliable playback recently, and plenty of players and upload forms still reject it.

Frequently asked questions

Will converting OGG to MP3 lose quality?

A small, one-time generational loss is unavoidable. Both OGG and MP3 are lossy, so re-encoding discards a little more detail. The converter uses high-quality settings to keep it inaudible for speech, but if you still have the original uncompressed source, converting from that instead is always better.

Is it free?

Yes, completely, with no account and no watermark. The conversion runs on your own device, so it costs us nothing to let you use it. The only limit is file size: up to 50 MB, which is what a browser can hold in memory comfortably.

Do I need to install anything, or upload my file?

Neither. It runs entirely in your browser using FFmpeg compiled to WebAssembly. Your audio is never sent to us, which is also why it works on a slow connection, only the page downloads, not your file.

Need a transcript of the audio?

Autrans also transcribes audio in Nigerian English, Pidgin, Yoruba, Hausa, Igbo, French, and Spanish.
