Convert Ogg Vorbis or Ogg Opus to MP3

Choose or drop up to eight Ogg recordings. Review each file’s format, duration and size.
Keep MP3 selected and use the recommended 192 kbps CBR setting, or open Advanced settings for bitrate, VBR, sample rate and channels.
Press Convert to MP3. Download each completed result or use Download All for a ZIP.

Ogg is the container; Vorbis and Opus are codecs

An .ogg file commonly holds Vorbis, but it can also contain Opus or another codec. This page checks the contents and supports single-stream mono/stereo Ogg Vorbis and Ogg Opus with a known duration. It does not accept every codec that can be stored in Ogg, chained streams or surround recordings. Use Media Info to inspect an unfamiliar recording, or read Ogg Vorbis vs Opus.

Choose an MP3 bitrate for your recording

128 kbps: a smaller delivery copy; useful for speech when MP3 compatibility is needed.
192 kbps: the existing default for general music and listening.
256 kbps: a larger music copy with a higher encoding budget.
320 kbps: the highest CBR option here, with the largest bitrate-based size.

MP3 is useful for players that cannot open Ogg. Keep original channels for music; mono can suit speech but downmixes stereo. Auto sample rate keeps 48 kHz inputs at 48 kHz and uses 44.1 kHz for other rates. VBR Standard, High and Best use LAME V4, V2 and V0 and vary in size with content.

Quality, size and local processing

Vorbis, Opus and MP3 are lossy. Re-encoding cannot restore discarded detail and can introduce further loss, even at 320 kbps. Keep the original and audition the result. A higher output bitrate can make the MP3 larger; a one-minute CBR copy is approximately 0.96 MB at 128 kbps, 1.44 MB at 192, 1.92 MB at 256 and 2.40 MB at 320 before headers. Estimates are not measured output sizes.

Audio stays on your device. The worker processes one file at a time with limits of 32 MB per input, 10 minutes, 64 MB decoded PCM and 64 MB retained results. Devices reporting 2 GB RAM or less use a 16 MB PCM ceiling; other phones can also need smaller files. Cancel terminates the worker. Tags and artwork are not copied.

For a size comparison and original/output listening controls, use the Audio Compressor. For another output, use the Audio Converter or Opus to MP3.

GOOD TO KNOW

Audio conversion questions.

Why can’t my OGG file convert to MP3?

Ogg is a container, not a codec. This tool accepts valid single-stream mono/stereo Ogg Vorbis and Ogg Opus with a known duration. Other codecs, chained or multiplexed streams, surround audio, damaged files and files over the memory or duration limits can fail. Renaming a file does not change its codec.

What is the difference between Ogg Vorbis and Ogg Opus?

Both use the Ogg container and lossy audio compression, but Vorbis and Opus are different codecs. An .ogg extension alone cannot distinguish them. This page detects and decodes both; OGG output elsewhere on this site specifically means Vorbis, while OPUS output contains Opus.

Why might the converted MP3 be larger?

A higher MP3 bitrate than the source’s average bitrate can increase size. At 192 kbps, one minute uses about 1.44 MB before headers. Changing codecs does not guarantee a smaller file or restore quality discarded by the original lossy encoder. Estimated size is not the final measured size.

How should I choose an MP3 bitrate?

Open Advanced settings. CBR offers 128, 192 (default), 256 and 320 kbps. Try 128 kbps for speech or smaller copies, 192 kbps for general listening, and 256 or 320 kbps when a larger music copy is acceptable. Listen to the result; higher rates cannot recover lost detail. VBR Standard, High and Best are also available, with content-dependent sizes.

What should I do if conversion fails?

Read the file-row error, keep your original and try a valid smaller recording. Inputs must fit 32 MB and 10 minutes, with at most 64 MB decoded PCM, reduced to 16 MB on devices reporting 2 GB RAM or less. Cancel stops the worker; retry with Convert to MP3. If the engine cannot load, check the connection used to download engine assets or reload the page. Files are processed locally; tags and artwork are omitted.
