How to Reduce the File Size in Illustrator

The size of your file can increase greatly when you create an Adobe Illustrator document. You can optimize your document and create smaller files by using one or a combination of techniques, depending on your desired result.

You can also save your file as an EPS file format if you want to preserve several elements in your file while you shrink it.
