How to use this tool
- Drop your .ogg file on the box above, or click to browse.
- Set the MP3 bit rate and sample rate (defaults: 128 kbps, 44,100 Hz).
- Your browser decodes the Vorbis audio and LAME encodes the MP3 locally.
- Click Download. Nothing was uploaded.
Why you end up converting OGG to MP3
OGG (almost always Vorbis inside) is the format of game audio, open-source projects and plenty of voice recorders — MP3 is the format everything else plays. The conversion is lossy-to-lossy: Vorbis already discarded data when your file was made, and MP3 will discard more. For speech and casual music this is inaudible; for archival material, try to keep the original OGG as well.
One honest caveat about containers: OGG is a wrapper that can hold Vorbis, Opus, FLAC or video tracks, and browsers differ in which of those they decode. If your file is one of the unusual kinds, this page reports the failure clearly instead of handing you a silent MP3 — which is exactly the failure mode you want from a converter.
Size math
Vorbis files typically sit between 112 and 192 kbit/s. The MP3 you get is fixed by the bit rate you pick, not by the source: 128 kbps = 0.92 MiB per minute of stereo, 192 kbps = 1.38 MiB, 320 kbps = 2.30 MiB. If your source was a 160 kbit/s Vorbis, choosing 160 kbps MP3 gives a file of almost identical size with quality that holds up in blind tests against the source.
Why this page does not offer 64 kbps
The LAME encoder silently resamples audio below 112 kbps (stereo) or 64 kbps (mono) — the output file's sample rate stops matching the request. All bit rates offered here are verified above that boundary, so the settings you choose are the settings you get.
MP3 encoding on this page uses LAME (compiled to JavaScript as the lamejs library) under the GNU LGPL. Your audio never touches a server — only this page and the encoder library are fetched from the web.
Frequently Asked Questions
Is an online OGG to MP3 converter safe for private recordings?
This one is, in the sense that matters: your recording is never sent anywhere. The word 'online' describes where the page lives, not where your file goes — everything runs in this tab, and you can watch the network stay idle in your browser's developer tools.
Are my files uploaded to a server?
No. Your browser decodes the OGG and JavaScript in this page encodes the MP3. The only network activity is this page and the encoder library loading once.
My OGG file fails to decode — why?
Usually because the container holds something other than plain Vorbis — Opus, FLAC or a video track — and your browser does not decode that combination. Renamed files and truncated downloads fail the same way. The page tells you rather than producing a broken MP3.
Which bit rate should I choose?
128 kbps matches typical Vorbis sources and is the default; 192 or 256 kbps if the source was encoded at a high rate and you want minimal second-generation loss. Options below 112 kbps stereo are deliberately not offered — the encoder would quietly resample your audio there.
Does this work for voice memos and podcasts?
Yes — tick 'Mix down to mono' to halve the file size again; mono 128 kbps speech sounds fully clean, and a one-hour mono podcast lands around 55 MB at 128 kbps.
Can I convert several OGG files at once?
One at a time on this page — each conversion keeps the decoded audio in memory and a queue would risk crashing the tab on long files. Run them one by one; each replaces the previous download in memory.
