PSP file format is associated with PaintShop Pro, an image editing software developed by Corel. It is a proprietary format used for storing raster graphics created and manipulated within PaintShop Pro. PSP files support layers, channels, and various other advanced graphics elements, allowing for detailed and complex image editing. This format is primarily used for saving intermediate edits, enabling users to continue working on their projects with all elements intact.
A WEBP file is an image saved in the WebP (pronounced "Weppy") raster image format developed by Google for web graphics. It is designed to reduce image file sizes over standard JPEG compression while maintaining the same or similar quality. WEBP files allow images to be downloaded more quickly.
