Convert
Make OGG audio play everywhere
Convert OGG Vorbis files into MP3s that play on any device or editor, converted entirely in your browser.
For the best results: OGG files from game assets and open-source recorders convert best at 192 kbps. If the source was low-bitrate OGG, converting to 320 kbps MP3 will not improve it, match the output roughly to the source quality.
Advanced settingsoptional, defaults work well
Converted entirely in your browser, your files are never uploaded. Very large files depend on your device's memory.
What is OGG to MP3?
OGG to MP3 is a free file converter that re-encodes OGG Vorbis audio into universally supported MP3 files without uploading, queuing or watermarking anything. The audio is converted by an ffmpeg engine that runs inside your browser, so your recordings never leave your device. No upload, no queue, and no account, and once the engine has loaded it works even offline.

See it in action
Game-jam sound effects arrive as OGG, and the engine being used only imports MP3.
What you drop in
blast.ogg (Opus audio inside)
What you get
blast.mp3, decoded and re-encoded on-device, duration exact in testing whether the OGG contained Vorbis or Opus.
Tip: OGG is a container that may hold Vorbis or the newer Opus; both convert here without you needing to know which. Short effects convert in well under a second once the engine is warm.
Use cases
What people use it for
Convert OGG sound effects exported from a game project into MP3s for a video edit.
Turn OGG recordings made by open-source recorder apps into files an ancient office PC plays.
Change OGG music bought from an indie platform into MP3 for a portable player.
Who uses OGG to MP3?
Indie game developers
convert their Vorbis sound libraries into MP3s for trailers, promos, and tools that expect mainstream formats
Linux users
make recordings from open-source software playable for colleagues on locked-down Windows machines and dated hardware
Community radio hosts
turn contributed OGG segments into MP3s their playout system and aging studio computers understand
How it works
- 1Choose your files. They open in your browser, not on a server.
- 2Your device converts, compresses, or resizes them locally, with no upload.
- 3The converted files download straight back; nothing is kept anywhere.
Tips for the best results
- Choose a higher MP3 bitrate than the OGG source used, so the transcode adds no audible loss.
- Hold on to original OGG assets for game builds, where the format's efficiency still pays off.
- Convert a single test file first when handling a large sound library with mixed origins.
- Voice notes from chat apps are often Opus inside the same OGG container, and they convert here just as Vorbis files do.
- Once the engine has loaded, you can queue file after file without reloading the page.
FAQ
Frequently asked questions
What is OGG Vorbis in the first place?
Vorbis is a lossy audio codec developed by the Xiph.Org Foundation and released in 2000, usually carried inside the OGG container. It was built as a deliberately open, royalty-free alternative at a time when using MP3 meant paying patent license fees. That heritage made it a favorite of open-source software and game developers, who could ship it without legal costs.
If Vorbis is free and good, why convert to MP3 at all?
Because openness never translated into universal playback. Consumer electronics makers kept shipping MP3 decoders, so car stereos, older phones, some Apple software, and countless gadgets still shrug at an OGG file. MP3's patents expired in 2017, erasing Vorbis's licensing advantage, while MP3's compatibility lead remains. Converting is simply meeting your devices where they are.
Does OGG to MP3 conversion damage the sound?
Any lossy-to-lossy transcode discards a little more information, since the MP3 encoder cannot know which details the Vorbis encoder already removed and makes its own independent cuts. Encode at a generous bitrate, ideally higher than the source, and the difference stays below what ears pick up. Just avoid bouncing the same audio back and forth repeatedly.
Is the conversion done on my computer or yours?
Yours, exclusively. The page runs ffmpeg as WebAssembly directly in the tab, so the OGG never leaves your machine and the finished MP3 is assembled in local memory before downloading. There is no account, no queue, and no copy of your audio sitting on anyone's server afterwards, because no server was ever involved.
Where do OGG files even come from these days?
Mostly from software that prizes open formats: Audacity offers it as an export, many Linux tools default to it, indie game engines ship sound assets in it, and some open-source recorder apps write it. Certain music platforms with open-source roots also distribute in Vorbis. If a file arrived from any of those worlds, OGG is why.
What program can open an OGG file?
VLC, Audacity, Firefox, Chrome, and most open-source players handle OGG happily, and Windows added native support in recent versions. The gaps are older software, much of the Apple ecosystem, and hardware players. When you cannot control what the recipient uses, converting to MP3 removes the question entirely.
Is OGG higher quality than MP3?
At the same bitrate, Vorbis usually edges out MP3, especially at lower bitrates where its encoding is more efficient; at high bitrates both are transparent to nearly all listeners. Quality was never OGG's problem. Adoption was, which is why conversion to MP3 remains so common despite the technical scoreline.
Why does my OGG file fail to convert?
Rarely for codec reasons: the engine decodes both Vorbis and Opus, the two codecs OGG normally carries. A failure usually means the file is truncated or corrupted, perhaps a partial download or an interrupted export, or that a very long recording ran past your device's memory. Re-export or re-download the source and try again, on a computer if the file is large.
Are there any usage limits?
None. Everything is generated locally in your browser, so there is no server cost, no metering, and no daily cap, use it as many times as you like, completely free.
