This article explains how to format an SD card to FAT32, including instructions for both Windows and macOS.

You can format most SD cards to FAT32, but the process is a bit more complicated in Windows than it is in macOS. The problem is that the built-in Windows formatting tool won’t let you format a device to FAT32 if it’s larger than 32GB.

You can format larger SD cards on Windows, but only with a third-party tool. The built-in formatting tool on Mac allows you to format large SD cards without third-party apps.

If your SD card is 32GB or smaller, you can format it to FAT32 using Windows' Disk Management utility or the Command Prompt, but the easiest way is to use File Manager. If you have a card with more than 32GB of storage, skip to the next section for instructions on using a third-party tool.
