How to Expand/Shrink SD Card Volume Safely in Windows 11/10/8/7

Case 1. Resize SD Card Partition to A Small Size

SD cards can be used in a variety of devices. Some devices may only recognize SD cards with small capacities. If you only have a high-capacity SD card, you might need to shrink its partition.

If the SD card uses the FAT32 or NTFS file system, MiniTool Partition Wizard can help you shrink SD card size easily and for free.

Here is how to shrink SD card size using MiniTool Partition.

Step 1: Connect the SD card to your PC via an SD card reader. Then, launch MiniTool Partition Wizard. Right-click the SD card partition and choose Move/Resize.

Step 2: On the pop-up window, move the right boundary line of the partition to the left to determine the amount of space to reduce. Then, click OK.

Step 3: Click Apply to execute the shrinking operation.

Case 2. Resize SD Card Partition to 32GB

Some users wish to shrink their SD card partitions to a specific size of 32GB, primarily because the devices using the SD cards only support the FAT32 file system.

In this case, I recommend simply formatting the high-capacity SD card to FAT32 using MiniTool Partition Wizard. This resolves the device compatibility issue while still allowing you to utilize the card’s large capacity. Here is the guide.

Case 3. Expand SD Card Storage with Unallocated Space
