Image Format Comparison

AI vs PNG — Vector Artwork vs Rasterized Image

AI (Adobe Illustrator) files are vector artwork — mathematically defined lines and shapes that scale infinitely without pixelation. PNG is a rasterized image — a fixed grid of pixels. AI is for creating and editing; PNG is for displaying and distributing. The two formats serve different stages of the design workflow.

Quick Verdict

Use AI when…

Use AI for creating, editing, and archiving vector artwork — logos, icons, illustrations, typography, and print layouts. Always keep your AI source files.

Use PNG when…

Use PNG for delivering artwork to the web, social media, apps, presentations, and any context where the recipient won't have Illustrator. PNG with transparency is the ideal rasterized format for logos and icons.

AI vs PNG: Feature Comparison

Feature	AI	PNG
Format type	Vector (mathematical paths)	Raster (pixels)
Scalability	Infinite — no pixelation	Fixed resolution — degrades when upscaled
Editability	Full — paths, layers, effects	Pixel-only editing
Transparency	Yes	Yes (alpha channel)
Web compatibility	None — requires Illustrator	Universal
Print use	Preferred for professional print	Good at 300+ PPI

When AI wins

When PNG wins

✓Format type: Raster (pixels)
✓Scalability: Fixed resolution — degrades when upscaled
✓Editability: Pixel-only editing

Frequently asked questions

Should I send a client AI or PNG files?

Send PNG for approval, social media, and web use. If the client needs to edit the artwork (in Illustrator or similar), send AI. For print production, send AI or export as PDF with embedded fonts.

Can I open an AI file without Illustrator?

Modern AI files (CS5+) embed a PDF stream that Inkscape, Affinity Designer, and PDF viewers can open. Some features (live effects, linked images) may not render correctly outside Illustrator.
