Questions

Is converting AMR to AAC free?
Yes. ConvertBoy is free with no daily limit, no watermark and no sign-up.
Is there a file size limit?
No. Your own device does the work, so the only limit is your device's memory. Very large videos take longer on slower computers.
Are my files uploaded anywhere?
No. The conversion happens inside your browser. Your AMR files never leave your device, and nothing is kept after you close the tab.
Does it work on a phone?
Yes. It works in Safari on iPhone and Chrome on Android, as well as on any computer.
How long does it take?
A song takes a few seconds. A video takes roughly as long as it plays on an average laptop, less on a fast one. The first time, the converter loads its video engine (about 30 MB).
