How to Open a PSD File Without Photoshop
A .psd is a Photoshop document: not a picture but a stack of layers, masks and adjustments. That structure is why ordinary image viewers refuse it, and why it can be enormous.

.psb
Why it will not open
- It is not a flat image. A .psd holds every layer separately, along with masks, blend modes and text that is still editable — there is no single bitmap to display until something composites it.
- The format is proprietary and versioned. Applications that read it are reverse-engineering Adobe's structure, so support for newer features tends to lag.
- Files are frequently hundreds of megabytes, which rules out most web-based viewers that need to upload first.
How to open it
View and edit for free
- 1 Photopea runs in a browser and opens .psd with layers intact — the closest free equivalent to Photoshop for this purpose.
- 2 GIMP opens .psd and preserves layers, though some adjustment layers are flattened on import.
- 3 Krita also imports layered .psd and is better suited to painting work.
Just get a flat image
- 1 If you only need to see the artwork, ask the sender for a PNG or JPEG export — it is one menu item for them and avoids a large transfer.
- 2 Most .psd files include a flattened composite preview, which is what lets some file managers show a thumbnail. That preview is low-fidelity and not exposed as a separate file.
.psb is the same thing, larger
Photoshop switches to the .psb "large document" format past 30,000 pixels or 2 GB. It holds the same structure but fewer applications read it.
Fonts and linked files travel separately
A .psd references fonts by name and can link rather than embed placed images. Opening someone else's file on a machine without those fonts will substitute them silently, which changes the layout.
