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 M4R, or download everything as one ZIP if you converted several files.
The MP3 to M4R 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.
An iPhone only offers a sound as a ringtone if it is an M4R file, which is AAC audio with a ringtone extension, and no longer than about 40 seconds. After converting, the M4R still has to be added to the phone, either by syncing it with Finder, iTunes or the Apple Devices app, or by importing it through GarageBand on the iPhone.
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. An iPhone ringtone is limited to 40 seconds, so only 40 seconds are kept, from the start point you set under Options (the beginning by default). M4R is written at 192 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.

Connect the iPhone to a computer and drag the .m4r file onto the device in Finder (Mac), iTunes or the Apple Devices app (Windows). It then appears under Settings, Sounds & Haptics, Ringtone. On the phone alone, GarageBand can import the file and export it as a ringtone.
iOS accepts ringtones up to about 40 seconds, and alert tones up to about 30. Longer files are not shown in the ringtone list.
No. The MP3 to M4R conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
M4R 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 M4R. 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.
