QuickPSD guides

PSD is a graphics file format that stores an image as separate layers rather than a single flattened bitmap. Text, background, photos and effects stay separate, so you can edit each one independently.

Besides the layers themselves, a PSD file stores their names, order, opacity, blend modes and masks. It is a working format - handy for further editing, but heavier than a finished PNG or JPG.

You can open a PSD file directly in QuickPSD - just drag it into the browser window. There is no need to install heavy graphics software or create an account.

Everything happens locally on your device, so even large files open quickly and their contents never reach a server.

Layers are separate levels of the image stacked on top of each other. You can reorder them, hide them, adjust opacity and move their content without disturbing the other elements.

A blend mode controls how a layer's pixels combine with what is below - lightening, darkening or tinting them. It is a core tool for building effects.

PNG, JPG and WebP are output formats - they store a single flattened image ready to publish on the web. You lose access to layers, but the files are much lighter.

Do your working edits in PSD, then export the result to PNG (with transparency), JPG (small photos) or WebP (the lightest files for a website).
