WinMerge Overview
WinMerge is a free, open-source visual diff and merge tool for Windows used to compare files and folders and reconcile differences. It highlights changes line by line and character by character with color coding, supports three-way comparison and merging, and can compare entire directory trees to show which files differ, are missing, or match. It also handles image comparison and integrates with version control systems as an external diff/merge tool. Its clear visualization makes it a staple for resolving conflicts and reviewing changes. Plugins handle special formats such as archives and Word documents, and folder comparisons can be filtered to include or ignore chosen file types and subfolders. The offline installer (and a portable build) installs without a network connection. This page links straight to Winmerge's official WinMerge source.
