PostScript to ICO

Why convert PostScript to ICO?

The main difference: PostScript is a vector format, while ICO is a lossless format. ICO can have a transparent background, PostScript can't.

Supports transparent backgrounds

ICO can hold a transparent background. Convert your image first, then cut out the background or place it on top of other designs.

Create a favicon or app icon

ICO is the icon format every browser and Windows understands. Convert a square PostScript to get a favicon for your site or an icon for a desktop shortcut.

What is a PostScript file?

PostScript (.ps) is Adobe's page description language from 1984 - the language many professional printers speak. A .ps file describes a whole page or document as instructions for drawing text, shapes and images.

PostScript files mostly come from print workflows and "print to file" output. PDF was built on the same ideas and has replaced it for everyday use.

How to open a PostScript file

Ghostscript and GSview open PostScript files on Windows; macOS Preview handled them up to Monterey. Adobe Acrobat Distiller converts them to PDF. Converting to PDF or PNG is the easiest way to view one today.

Extension: .ps
Type: Page description language
Best for: Print jobs and printer workflows

What is an ICO file?

ICO is the icon format of Microsoft Windows and the classic format for website favicons - the little image in a browser tab. One ICO file can hold several sizes (16 × 16, 32 × 32, 48 × 48 and more), so the icon looks sharp everywhere.

ICO supports transparency, so icons can have rounded or irregular shapes. Modern sites often add PNG and SVG favicons too, but favicon.ico is still the universal fallback.

How to open an ICO file

Windows shows ICO files in File Explorer and opens them in Photos; Mac Preview opens them too. GIMP and online editors can edit them. To make one, convert a square PNG - or use the Favicon Generator for a complete set.

Extension: .ico
Sizes: Several in one file (16-256 px)
Transparency: Yes
Best for: Favicons, Windows icons
