How to convert flac to m4r on PC as I can't upload flac to iphone?

I am using the AudioToolset app. There is an online flac to m4r converter that works well for the conversion needs mentioned in the post. It is a completely free online conversion tool. When using it, users only need to upload FLAC files, and AudioToolset will automatically convert them to M4R format, which is very convenient.

1. Go to the official web page.
2. Click 'Choose File' to upload the flac files on your computer.
3. The default output is M4R, you can adjust the bit rate, if you need ringtone, less than 30 seconds.
4. Click 'Convert' and wait for the FLAC to M4R conversion to finish.
5. Tap Download to download the converted M4R on your phone and upload it to iPhone as ringtone.

Frequently Asked Questions and Solutions: 

1. Failed to upload: check the network, try small files.

2. M4R is not recognized: Make sure the duration is less than 30 seconds.

3. Slow conversion: refresh the page and retry.
