| Description | .ai (Adobe Illustrator Artwork) The .ai format is a proprietary file format developed by Adobe Systems for representing single-page vector-based drawings in either the EPS or PDF formats. The AI format is most commonly used for creating and editing vector graphics. It is primarily used with Adobe Illustrator, a popular vector graphics editing program. AI files are well-suited for logos and illustrations as they can be resized without losing image quality. |
| Technical details | The .ai file format, which is associated with Adobe Illustrator, is a proprietary vector-based drawing format that represents artwork in EPS or PDF formats. Unlike raster graphics (.jpg, .png), .ai files use scalable paths and points, making them ideal for resizable designs such as logos. Originally exclusive to Illustrator, they are now compatible with various graphic design software, although with some limitations. Based on PDF, .ai files support layers, artboards, and can include both vector and raster graphics. They maintain editability, allowing individual graphic elements to be modified. The file size varies depending on the complexity of the design and the number of embedded images. Adobe Illustrator offers backward compatibility for saving files in formats that are compatible with older versions, although newer features may not be preserved. These files are well-suited for professional printing and are essential for graphic designers and digital graphics professionals. |
