DVDFab UHD Copy is a comprehensive tool designed to help users make personal backups of their 4K Ultra HD Blu-ray movies. It efficiently removes all copy protections like AACS 2, AACS 2.1, and BD-J, allowing for seamless copying and backup processes. You can use this UHD copy software to copy a 4K Ultra HD Blu-ray disc, ISO file or Folder to another blank disc, ISO, or folder without sacrificing image or sound performance. Its main functions are explained below in detail.

Main Functions

  • Eliminate any copy protection from old or newly-released 4K UHD discs quickly and automatically.
  • Enable lossless copying of 4K Ultra HD Blu-rays to BD100 while maintaining sound quality features such as DTS-HD, TrueHD, DTS:X, and TrueHD Atmos.
  • Effectively compress BD100 to common BD50 or BD25 formats without compromising playback compatibility on all devices.
  • Choose from Full Disc mode (all content), Main Movie mode (main movie title only), or Clone/Burn mode (1:1 ratio clone) according to your needs for customized backups.

Now let's five into its three Copy Modes:

Full Disc

If you choose this option then DVDFab UHD Copy will copy the entire disc either to a blank BD50/25, or to an ISO file or to a folder with BD100 2160p quality. The Full Disc mode actually compresses the original BD100 disc content to fit in a BD50 or BD25 blank discs. The compression technology retains the 2160p quality and will fit in a BD50/25 disc.

You should be aware of this fact that BD-XL discs cost 10 times more than BD50 discs. So, it won’t be a nice idea to buy such expensive discs when you can get the same quality from BD50 discs at dirt cheap price. You should give credit to DVDFab UHD Copy for letting you save a lot of money on BD-XL discs.

Main Movie

A 4K UHD Blu-ray disc may have many videos like sample shots, making of the film content, directors’ cut videos etc. So, you may want to skip these videos and just want to copy the main movie only. You can do this by simply selecting the ‘Main Movie’ option. DVDFab will automatically select the main movie and will skip the rest.  

It is similar to the ‘Full Disc’ function, the main movie function actually compresses the BD100 2160p content to fit on a BD50/25 disc while retaining the 2160p quality. Here you don’t need to spend money on expensive BD-XL/100 discs and can get the job done with cheaper discs while retaining the 2160p quality.


If you just simply want to clone or burn your 4K UHD Blu-ray disc in a 1:1 lossless ratio then go with this option. The clone option can only clone an ISO file to a disc.

Bonus: DVDFab also features DVD Copy and Blu-ray Copy modes. Download DVDFab UHD Copy, and you can also get a free experience to copy DVD or Blu-ray discs to a blank disc with high audio and video quality.

Other Key Features

  • Retains original HDR10 image quality even when compressing discs, and Dolby Vision and HDR10+ are also preserved if there's no compression involved.
  • Synchronize meta info including movie title, cast details etc.
  • Utilize GPU H/W acceleration technologies to speed up the copying process significantly.
  • Work with DVDFab UHD Cinavia Removal to remove Cinavia watermarks present in most audio tracks of 4K UHD discs to deliver a clean audio.

How to Burn 4K UHD ISO to Disc with DVDFab UHD Copy?

You are now familiar with the DVDFab UHD Copy and know what it is and what it does. Now we will show you how to burn a 4K UHD ISO to a blank disc. We have mentioned that BD-XL is 10 times expensive than a regular BD50. So, it is not reasonable to buy a BD-XL for every disc burning task. Use the cheaper BD50 discs and get the same UHD experience as you would have gotten from a BD100 or XL disc. So, let’s check the requirements below for this task.
