Will my PostScript look like the original image?

Converting to vector traces your pixels into shapes. Logos, icons, signatures, line drawings and text come out clean; photos turn into a simplified, poster-style illustration. Pick black and white or up to 16 colors in the options.

Yes. Add up to 30 PPM files and convert them in one batch. You can even choose a different output format for individual files, then download them separately or together as a ZIP.

PPM / PNM to PostScript

Why convert PPM to PostScript?

The main difference: PPM is a lossless format, while PostScript is a vector format.

Where PostScript works best

PostScript is ideal for print jobs and printer workflows. Converting gives you a file that works in the apps and websites that ask for PostScript.

PPM / PNM vs PostScript: what's the difference?

Property	PPM / PNM	PostScript
Compression type	Lossless (exact pixels, larger files)	Vector (shapes, not pixels)
Transparent background	No	No
Animation	No	No
Where it opens	None	None (needs a PostScript viewer)
Used for	Simple uncompressed images for scientific and developer tools	Print jobs and printer workflows

What is a PPM / PNM file?

PPM, PGM, PBM and PNM are the Netpbm formats: deliberately simple, uncompressed image files from the 1980s. They store pixels as plain numbers, which makes them easy for programs to read and write.

You'll mostly meet them in scientific computing, image-processing scripts and developer tools - rarely in everyday use.

How to open a PPM / PNM file

GIMP, IrfanView, XnView and Photoshop open Netpbm files, as do Linux image viewers. Windows Photos and browsers can't, so convert to PNG for a lossless, much smaller copy.

Extensions: .ppm, .pgm, .pbm, .pnm
Compression: None
Best for: Scientific and developer tools
Family: Netpbm

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
