What is a BRUSHSET file?
A .BRUSHSET file is a Procreate Brush Set created by Savage Interactive. It contains a collection of digital brushes for the Procreate iPad application. Artists use these files to bundle multiple custom brushes together for easy sharing and installation. Internally, a .BRUSHSET file is a standard ZIP archive that stores multiple individual .BRUSH files along with metadata and thumbnail images.
How to open BRUSHSET files?
The standard way to open a .BRUSHSET file is to import it directly into Procreate. You can do this by tapping the file on your iPad, which automatically adds the brushes to your brush library. Because the file relies on standard ZIP compression, you can also rename the file extension to .ZIP and extract the contents on a computer using archive tools like WinRAR, 7-Zip, or the built-in macOS Archive Utility.
Best practices and troubleshooting
If your .BRUSHSET file fails to import, ensure your iPad runs a recent version of iOS and Procreate, as older versions might not support newer brush engine features. If you are working on a desktop computer, note that you cannot use these brushes natively in Adobe Photoshop, as Procreate uses a proprietary brush engine entirely different from Photoshop's .ABR format.
Software and tools
You primarily use Procreate on iPadOS to manage and apply these files in digital art workflows. For internal inspection, developers and advanced users can use command-line utilities like `unzip` to access the raw data structure and brush configuration files inside the archive.
Summary
viewer.online/brushset analyzes .BRUSHSET files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. Because .BRUSHSET files use the known ZIP format, viewer.online/brushset can safely open and display them online, eliminating compatibility problems.
