The PSPMASK file type is associated with Corel PaintShop Pro, a popular image editing software. It is specifically used for storing mask files, which are templates that allow users to isolate and protect certain parts of an image during editing, enabling selective adjustments without affecting the rest of the image. These mask files can be applied to various layers or images to create effects, composite images, or perform non-destructive editing. PSPMASK files facilitate complex photo editing tasks by allowing users to blend, alter, or remove specific portions of an image with precision.
Based on HEVC (High-Efficiency Video Coding), the HEIF format is an image file container with one or multiple images and is the default image format for Apple Live Photos. It replaced the JPEG format as it's smaller in size and has lossless compression ensuring high-quality photos.
