Have you encountered a problem with a AI file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a AI file here. In the further part of this page we have added a list of programs that should open your AI file. It is enough you choose a proper application for your operating system, download and install it.


An AI file is a file of the vector based drawing program Adobe Illustrator. The AI format is a proprietary format containing one-sided vector drawings stored in either EPS or PDF format.

In addition to Adobe Illustrator, there are also a number of commercial and freeware drawing programs that can import or import AI files. However, since Adobe further develops the AI format, it can happen that with foreign software AI files that were created with a newer Illustrator version (CS3, CS4, CS5) can not easily import.

Remedy here either only the most recent version or the file in the Illustrator as a compatible version to save (just save when saving an older Illustratorversion)

Programs which can open a AI file

How to open a AI file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the AI file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a AI file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support AI files. At this point we are looking for disk space where the application was installed in and we can link it with a AI file. Since then, our operating system will use the selected program to support all AI files.

Other issues

Despite the described problem with AI there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the AI file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the AI file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
