Drop MP3 files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
Press Convert. Open Options first if you want to change the defaults. The work happens in this tab.
Save the OGG, or download everything as one ZIP if you converted several files.
The MP3 to OGG converter is part of this page and runs inside your browser. Your audio files are never sent to ToAny or to anyone else.
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
MP3 is lossy, so editing or re-saving it repeatedly degrades the sound. Ogg is open and royalty-free, which game engines and open-source tools favour. MP3 is at home in music and podcasts that must play anywhere; OGG is the usual choice for royalty-free audio in games and on the web. Both formats are lossy, so the content is compressed a second time; start from the best copy you have.
The defaults suit most files. Under Options you can choose the bitrate and trim the start and end.
The conversion uses your browser's own video and audio codecs (WebCodecs), with hardware acceleration where the device has it; the file is read from disk as it goes and can be up to 2 GB. Where the browser lacks a codec, the page falls back to the compatibility engine. OGG is written at 160 kbps unless you choose another bitrate.
MP3 is the audio format everything plays. It shrinks audio to roughly a tenth of its uncompressed size by discarding sound most listeners cannot hear. Newer codecs are more efficient, but nothing matches its compatibility.

MP3 converterOgg is an open container, most often holding Vorbis audio. Games, Linux software and Wikipedia use it because it is free of patents. Apple's players do not support it natively.

No. The MP3 to OGG conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
OGG is a lossy format, so a small amount of detail is traded for a smaller file. At the default setting the difference is hard to notice. You can choose the bitrate under Options.
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the MP3 file, press Convert and save the OGG. There is nothing to install.
Yes. Files up to 2 GB are accepted. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
