AI vs EPS Vector Formats

AI is Illustrator's modern native format with full feature support, while EPS is an older format valued for broader legacy compatibility.

Feature Support and Editability

The AI format preserves the full range of Illustrator's modern features — layers, effects, and editable text — exactly as created, while EPS, though still widely supported for import across many older and newer applications, can lose some Illustrator-specific editing capabilities when a file is saved down to that older, more universally compatible format.

When to Choose Each Format

AI is the right choice for an actively edited working file staying within the Illustrator or broader Adobe ecosystem, while EPS remains useful specifically when sending artwork to an older print vendor or a legacy software system that expects that older, more broadly compatible vector format rather than a native Illustrator file.

Frequently Asked Questions

Is EPS becoming obsolete compared to AI or SVG?

EPS usage has declined significantly in favor of AI for Adobe workflows and SVG for web use, though it remains occasionally requested by certain print vendors and older production systems still built around that format.

Can I convert an AI file to EPS if a vendor specifically requests it?

Yes, Illustrator includes a direct 'Save As' option for EPS format, making it straightforward to produce an EPS version of a design originally created and saved as a native AI file.
