Can I convert Photoshop PSB to PostScript on iPhone, Android, Mac or Windows?

Yes. ConvertPixels works in Safari, Chrome, Edge and Firefox on any device, so you can convert Photoshop PSB to PostScript on your phone or computer without installing an app.

Is there a free PSB to PostScript converter with no sign-up?

Yes, this one. Converting PSB to PostScript on ConvertPixels is free, with no sign-up, no watermark and no daily cap. Convert up to 30 files per batch, each up to 50 MB.

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.

Does PostScript keep the transparent background of my PSB?

No - PostScript has no transparency, so see-through areas get a solid fill. That's white unless you pick another background color in the options.

Can I batch convert PSB to PostScript?

Yes. Add up to 30 PSB 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.

Is it safe to upload PSB files to ConvertPixels?

Yes. Uploads use an encrypted connection and are processed automatically - nobody views them. Your originals are deleted straight after conversion and the results within an hour, or instantly if you click "Delete from server now".

Photoshop PSB to PostScript

Why convert PSB to PostScript?

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

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.

What is a Photoshop PSB file?

PSB (Photoshop Big) is Photoshop's large document format. It works like PSD, with layers and effects, but allows images up to 300,000 pixels wide and files bigger than 2 GB.

You'll find PSB files in panoramas, large-format print, billboard design and high-resolution scans - anything too big for a regular PSD.

How to open a Photoshop PSB file

Adobe Photoshop opens PSB files. Few other apps do, and their size makes them hard to share, so converting to JPG, PNG or TIFF is the usual way to view or send the final image.

Extension: .psb
Size limit: 300,000 × 300,000 px

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.
