AMR
AMR audio
AMR is a speech codec from the GSM era. Voice recorders and call recordings on older phones saved it. It sounds like a phone call and most modern apps cannot open it.
Opens in Older phones and VLC; few desktop players

How to convert AMR to OGG
Add your AMR voice recordings
Drop AMR 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.
OGG is already chosen
Press Convert. Open Options first if you want to change the defaults. The work happens in this tab.
Download
Save the OGG, or download everything as one ZIP if you converted several files.
Why ToAny

The AMR to OGG converter is part of this page and runs inside your browser. Your voice recordings are never sent to ToAny or to anyone else.
No upload, no queue
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
Free, without an account
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
AMR to OGG: what to expect
AMR does not open in most apps and browsers. Ogg is open and royalty-free, which game engines and open-source tools favour. AMR is at home in voice recordings on older phones; 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.
This pair uses the compatibility engine, ffmpeg built for the browser, because AMR is not handled by the browser's built-in codecs. It is a one-off download of about 10 MB that the browser keeps, it is slower than the built-in codecs, and it takes files up to 1 GB. OGG is written at 160 kbps unless you choose another bitrate.
AMR vs OGG
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

Questions
Are my voice recordings uploaded anywhere?
No. The AMR to OGG conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
Does converting AMR to OGG reduce quality?
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.
Can I convert several AMR 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 AMR to OGG 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 AMR file, press Convert and save the OGG. There is nothing to install.
Is there a file size limit?
Yes. AMR to OGG runs on the compatibility engine, which takes files up to 1 GB, and a long clip takes a while because it is slower than the browser's built-in codecs. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
