Image Format Comparison

EPS vs AI: Encapsulated PostScript vs Adobe Illustrator Format

EPS (Encapsulated PostScript) is a 30-year-old vector format supported by virtually every professional design and printing application. AI is Adobe Illustrator's native format. Both store vector graphics, but AI preserves Illustrator-specific features (layers, live effects, linked images) while EPS is the universal delivery format for print production.

Quick Verdict

Use EPS when…

Use EPS for delivering logos and graphics to print shops, marketing teams, and vendors. EPS is universally accepted by CorelDraw, InDesign, QuarkXPress, and prepress systems worldwide — even those that can't open AI files.

Use AI when…

Use AI when actively working in Illustrator and sharing files with other Illustrator users. AI preserves layers, live effects, swatches, symbols, and linked image paths — everything EPS strips out.

Frequently asked questions

Can CorelDraw open AI files?

CorelDraw can open AI files with varying success depending on AI version and features used. Older AI files (CS3 and earlier) open reliably. Newer AI files with complex features (3D effects, pattern fills, linked images) may not import correctly. EPS is the safer cross-application format — CorelDraw, Affinity Designer, Inkscape, and all professional tools read EPS without issues.

Is EPS still relevant in 2024?

For print production, yes — EPS is still the lingua franca for delivering vector artwork to print shops, embroidery shops, and sign makers. For web and screen: SVG is the modern replacement for EPS (open, smaller, editable, browser-native). EPS is a legacy format in the web context but remains essential in physical production contexts.

Can I open an AI file without Adobe Illustrator?

Yes: Inkscape (free, open source) opens many AI files. Affinity Designer handles AI imports well. CorelDraw can import AI. Adobe Illustrator viewer apps (iOS/Android) display AI files. However, proprietary Illustrator features — live text on a path, complex 3D effects, Illustrator-specific brushes — may not render correctly outside Illustrator. For reliable viewing by non-Illustrator users, export both AI (working file) and EPS (delivery file).
