OGG to MP3 Converter
This page decodes the audio inside your Ogg file and re-encodes it as an MP3 at a constant 192 kbps. Track tags follow the file, but embedded cover art does not survive the conversion.

Why convert OGG to MP3
Ogg is an open container, and the audio inside it is usually Vorbis. It turns up in game folders, in Audacity and LMMS exports, and in Wikipedia and archive downloads. The format carries no licensing fees, which is why software authors like it and why consumer hardware mostly skipped it: iPhones will not play a .ogg from the Files app, and many car head units, older portable players and video editors refuse it even though the audio itself is fine.
On our servers, ffmpeg 5.1.9 reads the Ogg stream, decodes it to raw audio and hands it to libmp3lame with a request for a constant 192 kbps. That is the only encoder setting on this page: no bitrate menu, no VBR switch, no sample-rate chooser, no loudness normalization and no noise reduction. The whole file is converted end to end, so a 40-minute Ogg recording comes back as a 40-minute MP3.
What comes through: the sample rate is kept up to 48 kHz, mono stays mono, and title, artist and album tags are rewritten as ID3 frames that any music player will show. Chapter markers, if your Ogg had them, are carried into the MP3. What changes: a rate above 48 kHz is lowered to 48 kHz, anything with more than two channels is folded down to stereo, and embedded cover images are discarded because the converter strips all picture streams. Both formats are lossy, so decoding Vorbis and re-encoding as MP3 is a second lossy pass: the MP3 will usually be larger than the Ogg it came from without sounding any better than the source.
The people who need this are mostly moving audio onto hardware that was never taught the format: a phone, a USB stick for the car, or a Bluetooth speaker that reads only MP3 and WAV from a card. The other common case is game and mod audio, where sounds ship as .ogg and have to become MP3 before a video editor or a sampler will touch them.
How to convert OGG to MP3 here
- Check the extension first. Files ending in .ogg are accepted; .oga and .weba are not recognized by the uploader. If your file is audio-only but ends in .oga, renaming it to .ogg usually works, because ffmpeg identifies the stream by its contents rather than its name.
- Drag the files onto the drop area or click to browse. Up to 10 files go in one batch without an account, and each may be any accepted audio source, so a folder with a mix of .ogg, .m4a and .flac files can be dropped together.
- There is nothing to configure. The target on this page is fixed to MP3, and the same encoder settings are applied to every file in the batch.
- Press Convert and wait on the page. Typical music and voice files, which is most of what comes through here, finish within a few seconds of the upload completing.
- Download each MP3. It keeps the original base name with the new extension, so sound_loop.ogg becomes sound_loop.mp3. The download link stays valid for about four hours, then the file is deleted.
- If the result is destined for a car stereo or an older portable player, play one file through before copying the whole set across, since very low-rate sources produce MP3s at reduced bitrates and unusual sample rates.
What this converter does
- ffmpeg 5.1.9 with libmp3lame, asked for a constant 192 kbps on every file
- Title, artist and album tags rewritten as ID3; chapter markers kept when the source has them
- Sample rate preserved up to 48 kHz; mono files stay mono instead of being padded to stereo
- Mixed batches: any accepted audio format can be dropped alongside your Ogg files and will also come back as MP3
- Nothing to install and no command line: the conversion runs on our servers, so Windows, macOS, Linux and phone browsers behave the same
- Output files keep their original names, which matters when you are converting a numbered set of game sounds or album tracks

OGG to MP3 questions
Will the MP3 sound worse than the OGG?
Slightly, in theory. The Ogg already had detail removed by whatever Vorbis encoder made it, and re-encoding that decoded audio as a 192 kbps MP3 removes a little more. On ordinary playback gear the difference is hard to hear, but it is a real second-generation loss, not a lossless copy.
Can I choose 320 kbps, or do I need VLC, Audacity or a command line?
This converter has a single fixed MP3 setting, a constant 192 kbps, with no quality, bitrate or sample-rate controls. VLC, Audacity and ffmpeg on the command line can all transcode Ogg to MP3 on your own machine and will let you pick 320 kbps or a small low-bitrate file, but they have to be installed and learned first. This page needs only a browser and gives you that one encoding setting.
Is there a mass or bulk mode for a whole sound library?
You can convert 10 files per batch as a guest or with a free account, 25 on Plus and 50 on Pro, and conversions are also capped at 10 jobs per hour per IP address on the free tiers. Large libraries have to be done in several batches; there is no folder upload and no single ZIP download of the results.
Are there size limits? Some sites advertise no limits.
There are limits here and we would rather state them: 50 MB per file without an account, 100 MB with a free account, 200 MB on Plus and 1 GB on Pro. Long recordings also have a 30-minute processing cap per file. Anything over 1 GB needs the separate pay-once large-file option, which requires signing in.
The conversion failed with an ffmpeg error about end of file or invalid data. Why?
Those two errors are what we see most on this pair, and both point at the file rather than the encoder: an incomplete download, a stream cut short, or something that is not really Ogg audio under a .ogg name. Re-download the file, or if you pulled it out of a game archive, extract it again and upload the fresh copy.
Does the album artwork come across?
No. Every picture stream is dropped during conversion, so an Ogg with embedded artwork produces an MP3 with no cover image. You can add artwork afterwards in a tag editor such as Mp3tag or in your music player's track info panel.
What happens to my files after converting?
Conversion runs on our servers, not in your browser. Your uploaded Ogg is deleted as soon as the job finishes, and the MP3 plus its download link are removed automatically about four hours later. File names, sizes and outcomes are recorded in our logs, and signed-in accounts keep a conversion history row.
