OGG to MP3 Converter
Turn OGG and Opus files, voice messages included, into MP3 that plays on any phone, car stereo or computer. Nothing is uploaded.
How to convert OGG to MP3
Three steps, all in your browser.
1. Choose your OGG or Opus files
Drop one or more .ogg, .oga or .opus files, up to 2 GB each. They are read on your device.
2. Pick the quality
MP3 at 192 kbps is chosen for you. 128 kbps is plenty for voice messages; 320 kbps keeps the most detail of music.
3. Convert and download
Press Convert. Each MP3 keeps the original name with the .mp3 extension.
About the formats
OGG – a container, usually with Vorbis
OGG is an open container. Music and game sounds in .ogg files are usually Vorbis; voice messages are usually Opus. Many iPhones, car stereos, older players and editors don't open either.
Opus and voice messages
Opus is the codec of WhatsApp, Telegram and Discord voice messages, saved as .opus or .ogg. It is built for speech at low bitrates, so a voice message converted to MP3 at 128 kbps keeps all of its sound.
MP3 – MPEG-1 Audio Layer III
The audio format with the widest support. At 192 kbps a minute of stereo music takes about 1.4 MB. WAV, M4A and FLAC are offered too.
Why people convert OGG to MP3
Keep or send a voice message
Save a WhatsApp or Telegram voice message as MP3 to play it on any device, add it to a video or send it to someone outside the app.
Sounds from games and apps
Many games and apps ship their music and effects as OGG. Convert them to MP3 for a phone, a video editor or a ringtone.
Files that won't open
When an iPhone, a car stereo, PowerPoint or an upload form refuses an OGG file, the MP3 version works.

OGG to MP3: frequently asked questions
How the converter works and what it can do.
How do I convert OGG to MP3?
Choose one or more OGG or Opus files above, keep MP3 selected (or pick a quality), press Convert to MP3 and download the result. It runs in your browser, with no upload and no queue.
How do I convert a WhatsApp voice message to MP3?
Save the voice message as a file first: on Android, share it from the chat or find it in WhatsApp's Voice Notes folder; on iPhone, share it from the chat and save it to Files. Then choose the .opus or .ogg file here and convert it.
Does it convert .opus files?
Yes. .opus, .ogg and .oga files are all converted, whether the sound inside is Opus or Vorbis.
Which MP3 quality should I choose?
128 kbps is enough for voice messages and keeps them small. For music, 192 kbps sounds like the original for most people; 320 kbps keeps the most detail.
Are my files uploaded?
No. The conversion runs inside your browser with a WebAssembly build of FFmpeg. Only the audio engine (about 31 MB) is downloaded, once; private voice messages never leave your device.
Can I convert several files at once?
Yes, up to 20 files at a time, each up to 2 GB. They are converted one after another with the same settings.
Can I convert Spotify downloads?
No. Songs downloaded in the Spotify app are encrypted and only play inside the app; no converter can open them.
Is it free?
Yes. It needs no account, adds no watermark and does not limit how many files you convert.
