Turn your OGG file into an MP3 that plays where you need it, right in your browser.
Drag and drop the file, or click to browse. Files up to 500 MB are supported, and nothing is installed.
MP3 is already selected. Switch between MP3 and WAV if you change your mind.

OGG is the open, patent-free audio container, usually holding Vorbis or Opus. WhatsApp voice notes and a lot of game audio ship in it, and Apple devices have never handled it gracefully.
The practical problem: iPhones, iPads and most car stereos will not play OGG. Podcast hosts and transcription services usually want MP3 or WAV instead.
MP3 solves that. Plays on every phone, car stereo, browser and podcast host in existence. Small enough to attach to an email or send in a chat. Accepted by every transcription and podcast service.
OGG is what WhatsApp voice notes and a lot of game audio ship in, and Apple hardware has never handled it. MP3 plays everywhere, which is usually the whole reason for the conversion.
| OGG | MP3 | |
|---|---|---|
| Container | Ogg | MPEG audio layer III |
| Typical codecs | Vorbis or Opus | MP3 (lossy) |
| Best for | Open-source projects, game audio, voice notes | Podcasts, voice notes, music you need to send |
| Plays on | Browsers and Android; poor on Apple hardware | Every device made in the last 25 years |
| File size | Small, efficient | Roughly a tenth of uncompressed audio |
Yes. Convert and preview the result for free, then create a free account to download it. There is no per-file charge and no watermark on the MP3 itself beyond the free-plan badge.
No. The conversion runs on our servers and the whole flow happens in your browser, so it works the same on Windows, macOS, Linux, iPhone and Android.
OGG to MP3 is a re-encode, so a small amount of detail is lost. At the default quality level the difference is inaudible on speech, and for music it stays well below what typical playback gear reveals.
Up to 500 MB per file. For anything bigger, trim or compress it first, both are free tools here.
Your upload is processed and then held only as long as your project needs it. Nothing is published, indexed or shared unless you create a share link yourself.
