Convert tcr to jp2

What is the difference between .tcr and .jp2?

Description: The TCR file format is associated with eBook files specifically used by Psion Series 3 devices. Psion Series 3, a range of personal digital assistants (PDAs) developed in the early 1990s, utilized these files to store and display electronic books (eBooks). TCR files are designed to be compact to suit the limited storage capacities of early PDAs. They contain the text of the eBook, and possibly basic formatting, optimized for the low-resolution screens of the Psion device.; A JP2 file is a compressed bitmap image created using JPEG 2000 Core Coding. It incorporates a wavelet compression algorithm instead of Digital Cosine Transform (DCT) compression, which is used by standard JPEG images. JP2 files can be stored using lossy and lossless compression.
