How to convert OGG to MP3
Add your OGG files
Drag and drop OGG files into the box or tap to choose them. The converter engine (about 31 MB) downloads once, the first time you convert.
Pick a bitrate
192 kbps suits music and 128 kbps or less suits speech. Sample rate and mono/stereo are under Advanced.
Convert and download
Click Convert, then download each MP3 file or all of them as one ZIP.
Why convert OGG to MP3?
OGG Vorbis files from games, Linux apps and some recorders won't play on iPhones, many car stereos and Windows Media Player. MP3 plays everywhere.
What happens when you convert OGG to MP3?
Fylo decodes the Vorbis audio and encodes MP3 at 192 kbps — similar size, small generation loss.
How does Fylo convert OGG to MP3?
Fylo decodes the Vorbis audio in the OGG with ffmpeg compiled to WebAssembly and encodes it with the LAME MP3 encoder at 192 kbps (adjustable from 96 to 320 kbps). Both formats are lossy, so each conversion discards a little detail — start from the highest-bitrate OGG you have. A 3-minute song is ≈ 3.6 MB at 160 kbps as OGG and ≈ 4.3 MB at 192 kbps as MP3. The original sample rate and channel layout are kept unless you change them under Advanced.
What's the difference between OGG and MP3?
Ogg is an open container from the Xiph.Org Foundation; Vorbis, the audio codec most .ogg files use, reached version 1.0 in 2002. Vorbis was created as a free, unpatented alternative to MP3 and sounds better at the same bitrate.
MP3 (MPEG-1 Audio Layer III) was developed largely at Germany's Fraunhofer Institute and standardised in 1993. It removes sounds the ear is unlikely to notice — a technique called perceptual coding — so a 3-minute song takes about 4 MB at 192 kbps instead of about 32 MB as WAV. The last MP3 patents expired in 2017, so it's now free to use.

Frequently asked questions
Why won't OGG play on my iPhone?
Apple apps generally don't support Ogg Vorbis. MP3 or M4A solves it.
Do OGG files contain Opus?
Sometimes; Fylo handles both Vorbis and Opus in Ogg.
Is my OGG file uploaded to a server?
No. Fylo runs ffmpeg, the same engine used by professional video tools, compiled to WebAssembly inside your browser. Your OGG file is read directly from your device and never sent anywhere.
