Convert OGG to MP3
Take an OGG Vorbis file and get an MP3 that plays on any phone, car stereo, or old media player. The conversion happens in your browser, so the audio never leaves your device.
Why convert OGG to MP3?
OGG is common in games and open-source tools, but it stumbles on a lot of consumer hardware: many cars, older phones, and plenty of apps simply will not open a Vorbis file. MP3 is the universal fallback that plays on nearly everything, from a decade-old head unit to a basic web player. Convert when you have exported audio from Unity, Godot, or Audacity as OGG and now need to share it, email it, or load it somewhere that only understands MP3. When you do not control what will open the file, MP3 is the low-risk default.
Quality and file size
OGG and MP3 are both lossy, so this is a transcode: the file gets decoded and re-encoded, which adds a small amount of generation loss on top of what OGG already discarded. In practice it is hard to hear if you pick a high bitrate, so choose 320 kbps (or 256 kbps) rather than something low. Avoid bouncing the same audio back and forth between lossy formats repeatedly, since each round trip stacks a bit more loss. For a one-time OGG to MP3 conversion at a high bitrate, most people will not notice a difference.
OGG to MP3: common questions
Will the MP3 sound worse than the OGG?
There is a small quality loss because you are re-encoding already-lossy audio, but at 320 or 256 kbps it is inaudible to most listeners. Pick a high bitrate and convert only once to keep it clean.
What bitrate should I choose?
Use 320 kbps for the best quality, or 256 kbps for a slightly smaller file. Lower bitrates like 128 kbps save space but make the extra generation loss easier to hear.
Is my file uploaded anywhere?
No. The conversion runs entirely in your browser using FFmpeg compiled to WebAssembly. Your OGG is never uploaded, and we never see it, store it, or train on it.
Why not just keep the OGG?
If every device and app in your workflow already plays OGG, there is no need. Most people convert because Vorbis support is patchy outside games and open-source software, and MP3 is the file they can hand to anyone without a second thought.
