How to convert NTFS to APFS in Disk Utility

"I use a Windows 10 machine for many years but my computer recently died. I am interested in changing over to a Mac machine to learn Photoshop and video editing skills. The main issue is getting my work documents and photos that I have worked on, which are on separate NTFS external hard drives. I believe I need to go from NTFS to APFS. I am not sure how to do it and keep all my files of the same quality at the same time. Anybody can help?"

--A user from Tom's hardware

When people want to move from the Windows platform to the Apple platform using an external drive formatted with the NTFS file system, they will always find that the files on the NTFS drive are non-editable and non-transferrable on Mac.

That's because macOS can't mount an NTFS drive on Mac with NTFS write support. That's to say, you can read NTFS drives on Mac but can't write to Microsoft NTFS-formatted drives on Mac.

Therefore, you must be considering converting NTFS to APFS to solve the inconvenience. This post will teach you how to convert NTFS to APFS without losing data so that you can use the external drive on Mac freely. But before converting NTFS to APFS, did you know what those two different file systems are? Did you know what advantages they have?

Knowing those might help you decide if you want to keep using the NTFS file system or move to the APFS file system.


What is the NTFS file system?

NTFS (New Technology File System) replaced the FAT32 file system and became the default file system in Windows 10, Windows 8, Windows 7, Windows Vista, and Windows NT operating systems. NTFS also is supported in other operating systems such as Linux and BSD. macOS only has NTFS read support and its NTFS write support is disabled by default and experimental.

NTFS has a lot of advantages compared to its former default file system FAT32. For instance:

  • It has higher security by controlling permissions to the files.
  • NTFS is optimized to be able to encrypt, decrypt, compress and decompress files.
  • NTFS deals with large files and partitions very successfully if you are using any external storage media larger than 32GB in Windows.

What is the APFS file system?

APFS (Apple File System) is Apple's newest file system coming with macOS High Sierra. macOS Ventura, macOS Monterey, macOS Big Sur, macOS Catalina, and macOS Mojave use APFS as the default file system as well. Windows doesn't have APFS support at all. You can't read nor write to APFS drives on Windows.

Compared with previous default file systems, HFS and HFS+, formatting external drives to APFS has a few advantages. For example:

  • It is optimized for faster read-write speed on SSDs and flash-memory devices.
  • It supports full-disk encryption and multiple copies of the same file.
  • It allows users to manage the disk storage more efficiently by having flexible free space.

There is certainly a gap between Microsoft NTFS drives and Mac operating system. If you want to use this external HD interchangeably between Windows and macOS, it is better to format an external hard drive for Mac and PC with FAT or exFAT format.

On the other hand, if you are going to move to macOS permanently and use the external drive on a Mac running macOS Ventura/Monterey/Big Sur/Catalina/Mojave/High Sierra, it is a good idea to convert NTFS to APFS since APFS is the primary file system in them now.

Does converting to APFS delete data? Converting a file system formatted on a drive might delete data. Therefore, you need to handle the process with care and back up your NTFS drive, or it might cause data loss. Check the section below to know how to convert NTFS to APFS without losing data.


Convert NTFS to APFS with the help of an NTFS-HFS converter

There is no software in the market that can convert NTFS directly to APFS yet, but there is software to convert NTFS to HFS+. So you have to make a detour - convert NTFS to HFS+ first and then convert HFS+ into APFS on Mac.

Step 1: Convert NTFS to HFS+ with a free Paragon NTFS-HFS Converter.

At this step, we need to seek help from Paragon NTFS-HFS Converter, a free tool that can easily convert NTFS drive to HFS+ and vice versa. It offers us an option to back up files on the NTFS drive to avoid data loss.

Another option that you can use APFS-formatted drives on Mac is to reformat NTFS into APFS.

Here are the steps about how to reformat NTFS into APFS without data loss:

Step 1: Back up files.

1. Connect the NTFS drive to the Mac.

2. Copy and paste the important data from the NTFS drive to the Mac. If your Mac doesn't have enough capacity for data backup, use another external drive formatted with a Mac-friendly format for backup.

If you have tons of data on the NTFS drive, it might take a while. But it's worth waiting if you don't want to lose your important data.

Step 2: Reformat NTFS to APFS in Disk Utility on Mac.

The process is very easy to follow.

1. Go to Finder > Applications > Utilities > Disk Utility.

2. Connect the NTFS drive to the Mac.

3. Click the NTFS drive.

4. Click "Erase" on the toolbar.
