How to convert OGG to AAC

  1. Add your OGG audio files

    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.

  2. AAC is already chosen

    Press Convert. Open Options first if you want to change the defaults. The work happens in this tab.

  3. Download

    Save the AAC, or download everything as one ZIP if you converted several files.

OGG to AAC: what to expect

Ogg does not play on iPhones, in iTunes or on many hardware players. AAC is more efficient than MP3 at the same bitrate. OGG is at home in royalty-free audio in games and on the web; AAC is the usual choice for efficient audio for streaming and video soundtracks. 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. AAC is written at 192 kbps unless you choose another bitrate.

OGG vs AAC

OGG

Ogg audio

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

AAC

AAC audio

AAC was designed as the successor to MP3 and is the audio codec inside most MP4 videos and streaming services. A bare .aac file is the raw stream without a container, which some players handle poorly.

Opens in Most phones, browsers and media players

Questions

Are my audio files uploaded anywhere?

No. The OGG to AAC conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.

Does converting OGG to AAC reduce quality?

AAC 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.

Can I convert several OGG files at once?

Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.

How do I convert OGG to AAC on Windows, Mac, iPhone or Android?

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 AAC. There is nothing to install.

Is there a file size limit?

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.
