AI File - opening and understanding

Did your computer fail to open an AI file? We explain what they are used for and recommend software that we know can open or otherwise handle your .AI files.

What is an AI file?

AI is the acronym for Adobe Illustrator. Files that have the .ai extension are drawing files that the Adobe Illustrator application has created.

The Adobe Illustrator application was developed by Adobe Systems. The files created by this application are composed of paths that are connected by points and are saved in vector format. The technology used to create these files allows the user to re-size the AI image without losing any of the image's quality.

Some third-party programs allow users to "rastersize" the images created in Adobe Illustrator, which allows them to convert the AI file into bitmap format. While this may make the file size smaller and easier to open across multiple applications, some of the file quality may be lost in the process.
