What is a ZXP file?
A .ZXP file is an Extension Manager Package created by Adobe Systems. Developers use this file type to distribute software add-ons for Adobe products, such as Adobe Photoshop and Adobe After Effects. These extensions add new features, panels, or tools to the base software. Under the hood, .ZXP files use the standard ZIP compression format to bundle HTML, JavaScript, and configuration files into a single package.
How to open ZXP files?
To install a .ZXP file, you need a package manager. Since Adobe stopped updating the original Adobe Extension Manager, you can use modern third-party tools like Anastasiy's Extension Manager or the open-source ZXPInstaller. Developers can also use the ExManCmd command-line tool from Adobe. Because a .ZXP file is an archive, you can manually extract it by renaming the file extension to .ZIP and using an extraction tool like 7-Zip or WinRAR.
Inspecting files with viewer.online
viewer.online/zxp analyzes .ZXP files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. If you have a file with an unfamiliar extension or suspect it might be something else, viewer.online/zxp will identify the actual format of the user's file.
Summary
Because .ZXP files use the known ZIP format, viewer.online/zxp can safely open and display them online, eliminating compatibility problems. You can explore the code and assets inside the extension without installing any software on your computer.
