What is a AI file?

AI files are vector graphics files created using Adobe Illustrator. The format was developed by Adobe Systems and is primarily used for creating scalable illustrations, logos, and design elements. Unlike raster images, AI files store paths and shapes based on mathematical equations, which allows them to be resized without losing quality.

This makes AI a preferred choice for professional graphic designers and print studios. The format is often used in combination with other Adobe tools and can be exported to formats like PDF, EPS, or SVG.

How to open AI files

AI files are best opened using Adobe Illustrator, but many other programs can handle them to varying degrees — including CorelDRAW, Affinity Designer, and some versions of Inkscape. Some PDF readers may open AI files because they often contain embedded PDF content.

If you just need to view or convert an AI file, online tools like AnyConv can also help.

What is a STL file?

STL (Stereolithography) is one of the most common 3D file formats used for 3D printing. It describes the surface geometry of a 3D object without including color, texture, or other attributes.

STL files are supported by virtually all 3D printers and modeling software. They are lightweight and easy to process, making them the go-to choice for rapid prototyping and additive manufacturing.

How to open STL files

STL files can be opened in most 3D modeling and slicing programs such as Blender, Cura, TinkerCAD, and Fusion 360. They are essential for 3D printing workflows.

Use AnyConv to convert STL files to formats like OBJ or STEP for further editing or integration with CAD systems.
