Question 1

Are vectors and quality kept when converting EPS to PDF?

Accepted Answer

Yes. Ghostscript rewrites the artwork into PDF without rasterising it: paths, fills and text stay vector, CMYK colours are preserved (unless you choose RGB) and the fonts in the file are embedded. At maximum quality, raster images inside are not downsampled below 300 dpi.

Question 2

How can I open or convert an .ai file without Illustrator?

Accepted Answer

Drop the .ai file here. If it contains a PDF (Illustrator CS and later with PDF compatibility on), we save it as PDF without re-encoding, all artboards included. Old PostScript-based .ai files are converted through Ghostscript. If the file was saved without PDF compatibility, the page will be empty — we detect that and warn you; re-save it in Illustrator with that option.

Question 3

Are my files uploaded to a server?

Accepted Answer

No. The conversion runs right in your browser (Ghostscript in WebAssembly) and the file never leaves your device — important for client artwork and logos. Only the engine itself, about 16 MB, is fetched once and then cached by the browser.

Question 4

How can the result differ from the original, and what are the limits?

Accepted Answer

If fonts aren't embedded in the EPS they are replaced with close ones; spot colours, overprint and complex overlaps may look different from Adobe — check the PDF before printing. Files are limited to 120 MB, and heavy files take longer and need a lot of memory.
