Бесплатный онлайн конвертер SK в PGX

This format is a vector images file in the Sketch Drawing program, which serves to edit and create interface designs, applications and software shells. SK-files contain objects and layers which can be edited independently of each other.

This is an image file format that is stored without the use of compression algorithms. It is used in the JPEG 2000 standard. This format is capable of storing only one single component, so it is limited to displaying grayscale tones. If you combine multiple PGX files, then you can make a color image.
