Lifewire's Picks: Free Disk Partition Software Tools for 2025

MiniTool Partition Wizard Free

MiniTool Partition Wizard includes more partition management tools than most similar programs, even ones you might pay for.

Not only does the free version support regular functions like formatting, deleting, moving, resizing, splitting, merging, and copying partitions, but it also can check the file system for errors, run a surface test, and wipe and align partitions.

Additionally, MiniTool Partition Wizard can move the operating system to a different hard drive and recover lost or deleted partitions. There's also a disk space analyzer and benchmark tool built in.

One thing I don't like is that it doesn't support manipulating dynamic disks. Also, compared to the paid versions, this one won't recover lost or damaged partitions.

Windows 11, 10, 8, 7, Vista, and XP are the confirmed supported operating systems.

AOMEI Partition Assistant SE

AOMEI Partition Assistant Standard Edition has a lot more options that are out in the open (as well as hidden away in menus) than many other free partition software tools, but don't let that scare you away.

You can resize, merge, create, and format partitions with this program, as well as copy whole disks and partitions.

Some of the partition management features are limited and offered only in their paid, professional version. One such feature is the ability to convert between primary and logical partitions.

If you want extra features like dynamic to basic disk conversions, you have to pay. The paid versions also support partition splitting and alignment, OS migration, partition recovery, and several other features.

This program can be used in Windows 11, 10, 8, and 7.

Macrorit Partition Expert

I love this app's user interface because it's super clean and uncluttered, making it very easy to use. All the available operations are listed on the side, and none of them are hidden away in menus.

Some actions you can perform on a disk include resizing, moving, deleting, copying, formatting, and wiping a volume, as well as changing the volume's label and running a surface test. It also supports OS migration and converting dynamic disks to basic disks.

Much like similar partition management software, Macrorit's program doesn't actually make any changes to the partitions until you apply them with the Commit button.

This program can run on Windows 11, 10, and older versions of Windows. A portable edition is also available. The Pro version has additional features like rollback protection and commercial use. To use this with a Windows Server OS, you'll need to pay for the Server or Unlimited edition.

IM-Magic Partition Resizer

IM-Magic Partition Resizer installs quickly and is super simple to use. You can use it to move, resize (even the active one), and copy partitions, as well as change the drive letter and label, check the partition for errors, delete and format partitions (even with a custom cluster size), convert NTFS to FAT32, hide partitions, and wipe all that data off.

All of those actions are extremely easy to find because you just have to right-click the device you want to manipulate. As you perform these actions, you'll see the program update in real-time to reflect them so that you can see how it will look when everything has been applied.

Then, when you're happy with the results, use the big Apply Changes button to put everything into action. If you have to reboot for anything to take effect, IM-Magic Partition Resizer will tell you so.

You can also view the properties of any drive, to see its NT object name, GUID, file system, sector size, cluster size, partition number, physical sector number, total number of hidden sectors, and more.

The only downfall I can see with this program is that a few of the features require that you upgrade to a paid edition. For example, you can't make the bootable media program that they support, or work with hard drives bigger than 16 TB, unless you pay for it.

The official list of operating systems that you can install this software to is Windows 11, 10, 8, 7, Vista, XP, and 2000.

NIUBI Partition Editor Free Edition

NIUBI's partitioning tool is extremely capable, despite it being the free version. Like most of the programs from this list, you can manipulate partitions in several ways.

There's an OS migration wizard and clone disk wizard, so if you need to do those things, it'll walk you through the whole process of choosing the source and destination locations.

Over 10 operations are listed off the left of the program for easy access. These let you do things like resize/move the volume, merge two volumes, delete or format a volume, repair the file system, run a surface test, and more.

Like most of these programs, you'll have to pay if you want things like commercial usage rights and access to the bootable media builder.

This program runs on Windows 11, 10, 8, 7, Vista, and XP.

GParted

GParted runs entirely from a bootable disc or USB device, but it still has a full user interface like a regular program, so it's not at all difficult to use.

Editing a partition's size is easy because you can choose the exact size of the free space before and after the partition, using either a regular text box or a sliding bar to visually see the size increase or decrease.

A partition can be formatted in any one of several file system formats, some of which include EXT2/3/4, NTFS, FAT16/32, and XFS.

Changes GParted makes to disks are queued up and then applied with one click. Because it runs outside the operating system, pending changes don't require a reboot, which means you can get things done that much quicker.

A small but particularly annoying issue is that it doesn't list all the available partitions on one screen like most other free disk partitioning programs. You have to open each disk separately from a drop-down menu, which is actually easy to miss if you're not sure where to look.

This download takes up a few hundred megabytes of space—much larger than most of the other programs on this list—so it may take some time to download.

EaseUS Partition Master Free Edition

Managing the size of a partition in EaseUS Partition Master is dead simple thanks to their easy-to-use slider that lets you drag left and right to shrink or expand a partition.

Changes you apply to a partition with this program aren't actually applied in real time. Modifications exist virtually, which means you're only seeing a preview of what will happen if you save the changes, but nothing is set in stone yet. Changes don't take effect until you click a certain button.

I particularly like this feature so things like expanding and copying partitions can be done in one swipe instead of having to reboot between each operation, thus saving tons of time. The list of pending operations is even shown on the side of the program so you can clearly see what will happen when you apply them.

You can also password-protect EaseUS Partition Master, hide partitions, upgrade the system drive to a larger bootable drive, merge partitions, defragment a drive, and copy Windows to a different hard drive.

One thing I don't like about this program is that several features are only available in the full, paid version, but are still clickable. This means you might sometimes try to open something in the free version only to be prompted to buy the professional one. OS migration, the WinPE Creator, and system cloning are some examples of paid features.

It works with Windows 11, 10, 8, and 7.

Paragon Partition Manager

If walking through wizards helps you feel more comfortable making changes to partitions, then you'll like Paragon Partition Manager. Whether you're creating a new partition or resizing, deleting, or formatting an existing one, this program has you move through a step-by-step process to do it.

Common file systems like NTFS, FAT32, and HFS are supported. Unfortunately, many additional features are disabled, available only in the pro version. These include disk backup, OS migration, and data wiping.

The supported operating systems include Windows 11, 10, 8, and 7.

Active@ Partition Manager

Active@ Partition Manager can create new partitions out of unallocated space as well as manage existing partitions, like resizing and formatting them. Simple wizards make it easy to walk through some of these tasks.

No matter what kind of file system you're using, this tool should be able to handle it, with support for all the common ones, like FAT, HFS+, NTFS, and EXT2/3/4.

There are other features, too, like imaging a whole drive for backup purposes, converting between MBR and GPT, creating FAT32 partitions as large as 1 TB, editing boot records, and rolling back changes by auto-backing up partition layouts.

When Active@ Partition Manager resizes a partition, you can define the custom size in either megabytes or sectors.

Unfortunately, it can't resize locked volumes, which means it won't let you change the size of the system volume.

This program should work just fine with Windows 11, 10, 8, 7, Vista, and XP, as well as Windows Server 2012, 2008, and 2003.
