About this format

PSD is a working format, not a final web image. It preserves layers, masks, adjustment layers, text, channels, and other Photoshop editing data.

Use PSD when you need to continue editing. Export to PNG, JPG, WebP, SVG, or PDF when you need to publish or share a flattened result.
