PPM / PNM to Photoshop PSD

Why convert PPM to PSD?

PPM and PSD are both lossless formats. PSD is the usual choice for layered Photoshop projects. PSD can have a transparent background, PPM can't.

Supports transparent backgrounds

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

Where PSD works best

PSD is ideal for layered Photoshop projects. Converting gives you a file that works in the apps and websites that ask for PSD.

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 Photoshop PSD file?

PSD (Photoshop Document) is Adobe Photoshop's native file format. It saves everything you're working on - layers, masks, text, adjustment layers and effects - so you can keep editing later.

PSD files are often huge and can only be fully edited in Photoshop or compatible apps. To share or post the design, you need a flattened image like JPG or PNG.

How to open a Photoshop PSD file

Adobe Photoshop opens PSD files fully. Photopea (free, in the browser), GIMP and Affinity Photo open most of them; Mac Preview and Quick Look show a flattened preview. Converting gives you the final image without needing Photoshop.
