  3. Use graphics conversion tools or online converters to change to SVG or EPS.

What is a .ai65 file?

The .ai65 file format is an older vector graphics file type used by Adobe Illustrator version 6.5. It was designed to store scalable vector artwork, allowing graphics to be resized without losing quality. These files contain instructions for drawing lines, curves, and shapes, making them ideal for logos, illustrations, and print designs. While newer Adobe Illustrator versions use the .ai format, .ai65 files are still relevant for users working with legacy design projects or older software. They can be opened and converted by modern graphics software, though some advanced features from newer versions may not be supported.
