Each disk partition manager in brief

1. EaseUS Partition Master

EaseUS Partition Master suits people who want a free tool for basic resizing and a paid licence for OS migration, cloning and recovery. Pro is $49.95 a year or $69.95 once, for 2 PCs. A named rollback feature protects partition changes. The catch: the free edition lacks OS migration, disk copy and partition recovery, and monthly prices differ between pages.

Best for: People who want one paid licence for two PCs with a rollback safeguard. Prices, facts and sources

2. AOMEI Partition Assistant

AOMEI Partition Assistant suits people who want a free edition that resizes, moves and merges partitions, or a paid one with a 90-day refund window. Professional is $49.95 a year or $69.95 once. The catch: no page names a rollback for interrupted operations, and the help page for allocating free space does not say whether partitions must be adjacent.

Best for: People who want a long refund window and a one-time licence for 2 PCs. Prices, facts and sources

3. 4DDiG Partition Manager

4DDiG Partition Manager covers most partition jobs: resize, merge, split, FAT32 to NTFS, MBR to GPT, OS migration, cloning and partition recovery. A year for one PC is $40.95 and a lifetime licence is $59.95, with a 30-day refund window. The catch: the vendor names no protection for interrupted operations, and merging works only on adjacent partitions.

Best for: People who want one paid tool for resizing, migrating and converting disks. Prices, facts and sources

4. NIUBI Partition Editor

NIUBI suits people who want one payment of $39 for two PCs, plus rollback if an operation is interrupted. The Free edition covers resize, move, merge and MBR to GPT conversion for home use. The catch: pages do not list splitting, FAT32 to NTFS conversion or partition recovery, and Free has no rollback or boot media builder.

Best for: People who want a low one-time price and a rollback feature. Prices, facts and sources

5. IM-Magic Partition Resizer

IM-Magic suits home users who want resize, move, merge, OS migration and disk cloning without paying. Pro adds boot media for $29.99 on two PCs on the buy page. The catch: pages show different Pro prices, and name no split, partition recovery or FAT32 to NTFS feature.

Best for: Home users who want free resizing, OS migration and disk cloning. Prices, facts and sources

6. DiskGenius

DiskGenius suits people who want a free edition that already handles resizing, splitting, GPT conversion and Windows migration. Paid editions add lost-partition recovery that can save the partition table. The catch: the cheapest year costs $99.90, the refund is conditional, and its pages do not list merging two partitions or FAT32-to-NTFS conversion.

Best for: People who want a free edition that covers resizing, GPT conversion and moving Windows. Prices, facts and sources

7. MiniTool Partition Wizard

MiniTool Partition Wizard suits people who want a free edition for everyday resizing and a paid one for OS migration and cloning. Pro is $59 a year for one PC. The catch: the only lifetime licence covers 5 PCs at $159, partition recovery is listed only for editions that cover 3 or 5 PCs, and no page names a rollback feature for interrupted operations.

Best for: People who need a free tool for resizing and a paid one for OS migration. Prices, facts and sources

8. Macrorit Partition Expert

Macrorit suits people who want a low-priced paid edition with boot media and roll-back protection, and a free edition for home use. Partition Expert migrates the OS and clones disks, and the free edition converts MBR to GPT. The catch: the vendor's pages do not say merge works in the individual editions, and name no split feature.

Best for: People who want a low-priced paid edition with roll-back protection. Prices, facts and sources

9. Parted Magic

Parted Magic suits people who want a bootable toolkit that resizes, moves, clones and recovers partitions on 64-bit x86 PCs. The Single Version costs $19 once and the journal resumes interrupted work. The catch: the vendor's pages do not describe merge, split or FAT32-to-NTFS conversion, and the refund window is 14 days at most.

Best for: Technicians and home users who want a rescue stick that boots 64-bit x86 PCs. Prices, facts and sources

10. BootIt Bare Metal

BootIt Bare Metal suits people who want a boot manager with partitioning, imaging and cloning in one tool, installed from its own boot media. The $39.95 Collection licence covers up to five household systems. The catch: all sales are final, and the vendor's pages do not describe merge, split or FAT32-to-NTFS conversion.

Best for: Multi-boot users who want one tool for boot menus, partitioning and imaging. Prices, facts and sources

11. GParted

GParted suits people comfortable booting a Linux live image who want a free resizer for NTFS, FAT32 and ext4. Its code is public and nothing is sold. The catch: its pages list no merge, no whole-disk clone, no Windows migration and no MBR-to-GPT conversion, and it is not a Windows app.

Best for: People who want a free, open-source resizer and can boot from a USB stick. Prices, facts and sources

12. Windows Disk Management

Disk Management suits people who need a quick shrink or extend on an NTFS drive and want nothing to install. It is built into Windows 10 and 11, and Microsoft's page lists no separate price. The catch: it cannot move space past a neighbouring volume or convert MBR to GPT without deleting volumes, and Microsoft's task list names no cloning or recovery.

Best for: People who only need to shrink a drive or add space next to it. Prices, facts and sources

Every fact, side by side

Each row is one rule of the method and the points it is worth. "–" means the vendor does not publish it, which earns nothing.

Head to head

We read each vendor's own pages, record every fact with its source and date, and score it by the rules on how we score disk partition managers. A tie goes to the lower price. Partition managers that run on Windows PCs, as an app, built into Windows, or from a bootable disc or USB stick that starts a Windows PC. Counts editions licensed for personal use on 1 or 2 PCs; business, server and technician editions are left out. Disk imaging and backup suites, data recovery suites and Mac-only tools are left out. Vendor claims about speed or quality are shown on product pages but never scored. Prices are in US dollars before tax.
