Can Clonezilla shrink partitions?

Clonezilla is an open-source disk cloning and imaging software that allows you to create copies or backup images of entire disks or individual partitions. Many users wonder if Clonezilla can shrink partitions, especially when trying to clone a larger partition to a smaller one. The short answer is no—Clonezilla cannot resize or shrink partitions directly. If resizing is necessary, you may need to shrink the partition using alternative solutions before cloning.

How to shrink a partition before cloning?

So, how can we safely shrink partitions? This section outlines three practical solutions to resize your partition. Before proceeding, it is advised to back up essential files to avoid potential data loss.

Fix 1. Use AOMEI Partition Assistant to Shrink Partitions

Since Clonezilla can’t shrink partitions, you’ll need to use other tools like AOMEI Partition Assistant to resize them. This is an excellent partition software and disk management tool for Windows 11, 10, 8.1, 8, and 7. With its 1-Click Adjust Space feature, you can easily and flexibly adjust partition space without losing data.

In addition to adjusting disk space, AOMEI Partition Assistant also offers many advanced features to simplify your disk partition management, including formatting partitions, wiping partitions, and moving partitions. Feel free to download this tool from the link below and give it a try.

Here’s how to shrink a partition using AOMEI Partition Assistant:

Step 1. Launch AOMEI Partition Assistant, right-click the partition you want to shrink, and select the 1-Click Adjust Space option.

1-Click Adjust Space

Tips: This tool does not support unallocated space adjustments directly. If unallocated space is available and you wish to expand the partition with it, use the Resize Partition tool instead.

Step 2. To use the space on F: to expand D:, simply drag the slider near the beginning of the F: partition backward to shrink it, which will automatically enlarge the D: partition. Then click OK to apply the changes.

Drag Dots

Alternatively, you can also drag the slider at the end of the C: partition forward to shrink it, which will further increase the D: partition size with the freed space from C:. This way, you can adjust the space of all three partitions on the disk simultaneously.

Step 3. After setting the desired adjustments, you can preview the changes in the Pending Operations window. Then click Apply and Proceed to confirm the operations.

Step 4. The process may take a few minutes. The partition sizes will be adjusted accordingly once the operation is complete.

Fix 2. Use Disk Management to Shrink Partitions

In addition to AOMEI Partition Assistant, Disk Management is also a good option to manage and change partition size on Windows devices. Here’s how to shrink your partition using this tool:

Step 1. Press Windows+R, type diskmgmt.msc, and press the Enter key.

Step 2. On the main page of Disk Management, right-click the partition you want to shrink, and then select Shrink Volume.

Shrink Volume

Step 3. In the pop-up window, set the amount of space to shrink and click Shrink.

Enter the Size

Step 4. Once the process is complete, the partition will be shrunk.

Note: Disk Management only supports shrinking NTFS partitions. Additionally, ensure that there is enough unallocated space on the right side of the target partition and that this unallocated space is adjacent to it. If these conditions are not met, consider using AOMEI Partition Assistant, which offers more flexibility for shrinking partitions.

Fix 3. Use DiskPart to Shrink Partitions

If you're comfortable using command-line tools, DiskPart provides an easy way to resize partitions. Follow these steps to shrink your partition via CMD:

Step 1. Press Windows + R, type cmd, and hit Enter to open Command Prompt.

Step 2. Type the following commands and hit Enter after each one.

  • diskpart
  • list volume
  • select volume X (replace X with the number of the selected volume).
  • shrink desired=Y (You can replace Y with the amount of space to shrink in MB and change "shrink" to "extend" to extend the partition).

 Shrink Volume via Command Prompt

Step 3. Type exit to close the window.
