To convert NTFS to FAT32 without losing data on Mac, you need to back up data on the drive to another storage device (computer or external drive) or a cloud service first and then reformat it in Disk Utility.
In fact, you should choose exFAT instead of FAT32 if the purpose of the drive is to transfer files on your Windows PC and Mac. That's because FAT32 only supports a maximum file size of 4GB and a maximum partition size of 2 TB. That being said, if you have a video file that's over 4GB in size, you can't store it on your FAT32-formatted drive. Or if you have a drive with more than 2TB of capacity, you can't format it with FAT32.
On the other hand, exFAT can store single files up to 16 EB and its maximum partition size is 64TB. To conclude, only use FAT32 when you don't need to save files larger than 4GB and the device you plan to use the drive with asks for FAT32.
Regardless, here's how to convert NTFS to FAT32 or exFAT on Mac without losing data:
- Back up files on your NTFS drive.
- Open Disk Utility from the Applications/Utilities folder in Finder.
- Click View > Show All Devices.
- Select your external NTFS disk and click Erase.
- Name your drive.
- Choose FAT32 or exFAT as the format.
- Select GUID Partition Map as the scheme.
- Click Erase.
- Copy the backed-up data to your formatted drive.
