What NextDiff is

NextDiff is a free Windows utility for comparing two files, text documents, source code files, or folders. It displays text files side by side and highlights changed lines as well as changes within lines. Folder comparisons include subfolders, identify files present on only one side, and can mark the newer file. Users can edit in the comparison view, copy differences in either direction, and undo recent merge or edit actions. Options allow comparisons to ignore case, whitespace, leading or trailing spaces, and blank lines. Supported encodings include ANSI, ASCII, UTF-8, UTF-8 with BOM, and UTF-16. Optional Apache Tika support extracts readable text from formats including PDF, DOCX, XLSX, and PPTX. The listed version is 2.2, dated September 23, 2026, and adds Preferences and support for new document formats. NextDiff is freeware for personal and commercial use on Windows 10 and 11. The maker says it runs locally without telemetry, cloud accounts, or data collection.
