FAQ

PCT to JP2 Conversion

What are PCT files?

PCT is an image file format associated with Macintosh QuickDraw, a graphics program developed in the 1980s as part of the Apple Macintosh operating system. The initial version of the format, called PICT 1, could store 8 colors, while the later developed PICT 2 supported 24 and 32-bit color images. In recent years, the format has decreased in popularity, being gradually replaced by more versatile formats.

What are JP2 files?

JP2 or JPEG 2000 is an improved version of JPEG, one of the most popular file formats for storing and transferring images. Compared to the latter, JP2 image files offer higher quality and smaller size images by using a different compression algorithm, which can be either lossy or lossless. JP2s are created using the JPEG2000 Core Coding application, but can also be obtained through conversion from other formats.
