Opening API files

Did your computer fail to open an API file? We explain what API files are and recommend software that we know can open or convert your API files.

What is an API file?

API is an acronym for Adobe Plug-In. Files that contain the .api file extension often consist of plug-in utilities that are used by a variety of different Adobe applications.

The API files that are used by Adobe programs provide users with added features and functionality in the associated Adobe software.

The Adobe PhotoShop file also uses the .api file extension, but not for plug-in files. This Adobe program uses the .api file suffix for ink color settings.

The Apple WebObjects software program also uses the .api file suffix. These files contain the interface files that are used by the WebObjects utility.
