I had a huge, problematic file to convert that couldn't go through the usual automated conversion process. The Zamzar team responded quickly to my request for help, and they took the extra steps needed to do it manually.

I've used this product for years. And customer service is excellent. Just had an issue where I was charged and I didn't agree with the charge and they took care of it, even though they didn't have to.

Fantastic service! My mom's computer died and she has 1000+ Word Perfect files she wants to keep for some reason. Since Word Perfect is basically dead, I decided to convert all her files. Zamzar's converter was perfect.

MP3 Audio Format

MP3 Converter

MP3 goes by the full name of MPEG Audio Layer-3 and is perhaps the most widely used audio file around today. MP3 is a file format developed by the Moving Pictures Expert Group (MPEG) which uses compression to produce smaller file sizes. The type of compression used means some data is lost, but typically audio playback quality is not obviously impacted, especially when recording files at higher bitrates. Other popular audio formats, such as WAV, can be up to 10 times the size of an equivalent MP3 file. Almost all applications are able to open MP3 files including Windows Media Player and iTunes on macOS. The MP3 file format famously exploded in popularity during the '90s and '00s as music moved online and become digitised.

M4R Audio Format

M4R Converter

An M4R is often referred to as an iPhone ringtone file. Developed by Apple, an M4R file is similar to an M4A file with the main difference being that an M4R file can only be 30 seconds in length and they are typically converted using iTunes itself. The way they work is a user selects a song they from their iTunes library that they want as a ringtone and they saved it as an M4R file and reimport back into iTunes giving them their own custom ringtone.

To avoid piracy M4R files can only created using music that has been purchased from iTunes. M4R files can be played by iTunes and on all Apple devices, and can also be played via the VLC media player but to play an M4R file using a program that isn’t Apple based would mean a user has created the file using software that is not linked with Apple and therefore do not include copyright protection.

Frequently asked questions

There are three main ways to convert MP3 files to M4R iPhone ringtones. You can use a free online conversion tool like Zamzar to quickly and easily convert multiple files at the click of a button. You can also convert files by converting them to AAC in your iTunes account, then renaming them as .M4R files; however, you would need to change each individual audio track, so it can be quite time consuming if you have a lot of files.

Another way is to convert your files using a downloaded software, such as Wondershare UniConverter, although you may need to pay to use the software and would need to install it on your device.

If you want to create an M4R ringtone file, Zamzar’s easy conversion tool could help. You can upload individual or multiple music tracks to Zamzar and convert them for free using the three-step tool, without downloading any additional software. Another option is to convert or rename audio tracks to .M4R using iTunes or using a media-editing software you install on your computer, such as Wondershare UniConverter.

You can easily turn any MP3 audio file into a ringtone for your iPhone. Online conversion tools like Zamzar let you quickly and easily create iPhone ringtones in real time. Just upload your MP3 file to Zamzar’s website, click to convert it, and then download a converted M4R ringtone file. Alternatively, you can do this using your iTunes library, by selecting tracks and converting them, first to AAC and then changing the file extensions to .M4R.

Either M4R or MP3 may be better for you, depending on what you’re using the track for. MP3s are better for playing music. But if you want to turn your songs, audio clips or voice notes into an iPhone ringtone or alarm, you’ll need to convert it to an M4R file. It will also take up less space on your device. Zamzar’s easy MP3 to M4R converter lets you quickly create new iPhone ringtone files. It’s a simple three-step tool – just upload, click to convert, then download your file.

If you have a Mac, there are a couple of ways you can change MP3 files to M4R without downloading any extra software. Zamzar’s online conversion tool lets you quickly convert individual or multiple MP3s into M4R iPhone ringtone files. Alternatively, you can manually convert files to M4R using iTunes, or by downloading media-editing software. However, it can be time consuming to convert files manually, and downloaded software takes up memory on your Mac and may cost money to use.
