PSB images: Frequently Asked Questions

What are PSB files?

PSB (Photoshop Large Document Format) is Adobe Photoshop’s file format designed to handle exceptionally large images that exceed the limitations of the standard PSD format. While PSD files support a maximum size of 30,000 x 30,000 pixels, PSB files can store images up to 300,000 x 300,000 pixels and beyond 2 GB in file size, making them ideal for high-resolution projects such as large-scale prints, maps, or architectural renderings.
PSB files preserve all Photoshop features — including layers, masks, effects, and color modes — and are essential for professionals working with ultra-high-resolution content that requires complete editing flexibility.
