What is Compare It!?
Compare It! helps you inspect differences between two files and move selected changes from one to the other. Its side-by-side view combines colored change blocks with an overview bar, so you can locate differences before editing or merging. The publisher documents direct editing inside either comparison pane, syntax highlighting and word wrapping for long lines.
For source-code reviews or revisions to text documents, it offers a focused file-to-file workflow rather than a folder synchronization interface. You can copy changes across the comparison, edit the result and generate an HTML report or colored printout. The publisher also lists detection of moved sections, comparisons with ZIP-contained files, and separate binary and image viewers. These are documented capabilities, not results of an installation or hands-on test.
Check the legacy documentation before choosing it for a current Windows system. The download catalog labels the package 4.2, while the overview and screenshot gallery describe 4.0; the image here therefore illustrates the older documented interface. Exact Windows 10/11 support and processor architecture were not established by the sources inspected. Compare It! is commercially licensed, not freeware.

Good to know

- The catalog lists version 4.2, but the product overview and supplied screenshot describe 4.0. The linked installer was not installed or inspected internally.
