Drop OGG 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 M4A, or download everything as one ZIP if you converted several files.
The OGG to M4A 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.
Ogg does not play on iPhones, in iTunes or on many hardware players. M4A sounds better than MP3 at the same file size and is native to Apple devices. OGG is at home in royalty-free audio in games and on the web; M4A is the usual choice for music and voice memos on Apple devices. 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. M4A is written at 192 kbps unless you choose another bitrate.
Ogg 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.
Opens in Chrome, Firefox, Android, VLC; Apple devices need extra software

No. The OGG to M4A conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
M4A 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 OGG file, press Convert and save the M4A. 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.
