PTK to JP2 Conversion: FAQ

What are PTK files?

The PTK format was initially developed by IBM as a Presentation Text Object Content Architecture (PTOCA) format, used in document processing. Such files contain parts of a larger document and single-page or multi-page segments of text. The PTK format is now considered rare and is no longer supported by its developer.

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.
