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 HDR 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.

Radiance HDR to PostScript

Why convert HDR to PostScript?

The main difference: HDR 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.

Radiance HDR vs PostScript: what's the difference?

Where it opens	None	None (needs a PostScript viewer)
Used for	3D lighting (HDRI environment maps) and visual effects	Print jobs and printer workflows

What is an Radiance HDR file?

Radiance HDR (.hdr) is a high dynamic range format that stores the real brightness of a scene, far beyond what a normal photo can hold. It's used for HDRI environment maps that light 3D scenes, and in visual effects.

HDR files look flat or blown out in ordinary viewers because screens can't show that range directly - they need tone mapping, which converting to JPG or PNG applies.

How to open an Radiance HDR file

Photoshop, GIMP, Blender, Affinity Photo and most 3D software open .hdr files. Mac Preview shows a basic preview. Convert to JPG or PNG to get a viewable, shareable image.

Extensions: .hdr, .pic
Range: High dynamic range (32-bit float)
Best for: HDRI lighting, visual effects
Also called: RGBE

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
