AI is Adobe Illustrator's format — modern versions are PDF-compatible PostScript programs, which is exactly why Ghostscript can open them without Illustrator.
Typical use: Convert AI artwork to PNG/JPG previews or PDF when Illustrator is not available.
About the AI format
AI is Adobe Illustrator's native format — and since Illustrator 9 it is literally a PDF-compatible PostScript program: open an .ai in a text editor and you will see a PDF header with Illustrator-private comment streams. That dual nature is why the format renders correctly in Ghostscript even without Adobe's own runtime.
Converting AI to PNG/JPG gives clients and web pages an instant preview; converting to PDF keeps every vector for print. Either way the file never leaves your browser.
