Convert MP3 to OGG
Free · localChoose a compatible MP3. No audio upload or account required.
Creates Ogg Vorbis at 48 kHz from browser-decoded mono or stereo MP3. Input and output must each fit 50 MiB; input must be no longer than five minutes. Vorbis is lossy and can discard detail; if the source was previously lossy, it cannot recover detail already missing. Timing, tags and artwork may not be preserved. Browser and player codec support varies.

How to convert MP3 to OGG
- 01 / CHOOSE
Select an MP3
Choose a compatible MP3 no larger than 50 MiB and no longer than five minutes. The browser must decode it to mono or stereo.
- 02 / CONVERT
Choose Vorbis quality
Pick a variable-bitrate quality setting and convert locally. The browser decodes and resamples the audio to 48 kHz before encoding Ogg Vorbis.
- 03 / CHECK
Listen and download
Preview if your browser supports Ogg Vorbis, then download and test the result in its intended player. Keep the original MP3.
Format and quality
What happens when MP3 becomes OGG?
OGG is a container; this tool creates an Ogg file containing Vorbis audio. Confirm that the destination supports Ogg Vorbis, not just an OGG extension or a different codec. Browser preview support varies.
Both MP3 and Vorbis use lossy compression. Converting an MP3 creates another lossy encoding and may discard additional detail; choosing a higher quality setting cannot recover information already lost. When available, start with an uncompressed or lossless master instead. Compare difficult passages such as cymbals, quiet speech and the ending.
Variable bitrate means file size depends on both the signal and the quality setting. A higher setting generally needs more data, but the output is not guaranteed to be smaller than the original. The converter resamples to 48 kHz; codec delay or padding can affect timing, and tags and artwork are not copied. Check sync before using the result in a video or multitrack session.
Troubleshooting
Check compatibility and limits
If conversion fails, check that the file is a readable MP3, meets the size and duration limits and decodes to no more than two channels. Output must also fit 50 MiB. Browser support varies; for long, multichannel or unsupported files, use a desktop converter. Renaming a file does not change its codec.
For the other direction, try OGG to MP3. To make an editing copy, use MP3 to WAV, bearing in mind that WAV cannot restore missing detail. The MP3 and WAV guide explains the tradeoffs.
This converter uses @audio/encode-ogg, with libvorbis via wasm-media-encoders. See the encoder license, wrapper license, Vorbis notice and Ogg notice.
A few useful answers
Free MP3 to OGG converter questions
How do I convert MP3 to OGG?
Choose a compatible mono or stereo MP3 up to 50 MiB and five minutes, select a Vorbis quality and convert. Preview and download the OGG locally. The output must also fit 50 MiB.
Does the converter upload my audio?
No. The browser reads and converts the selected file locally. Download the result before leaving the page.
Does MP3 to OGG improve quality?
No. MP3 and Vorbis are lossy codecs. A new encode can discard more detail, and a higher setting cannot recover information already lost in the MP3.
What kind of OGG does this create?
The output is Ogg Vorbis at 48 kHz with a variable bitrate. Check that the destination supports Vorbis; OGG is a container that can hold different codecs.
Why might the file fail to convert or play?
The source may be unsupported or exceed a limit, or the destination may not support Ogg Vorbis. Try a compatible browser or desktop converter and test the downloaded file in its intended player.
