NextDiff
NextDiff is a free Windows utility for comparing files, text documents, source code, and folders. It places text files side by side, marking changed lines and changes inside lines. Folder comparisons include subfolders, reveal files found on only one side, and can identify the newer file. You can edit text in the comparison view, copy differences in either direction, and undo recent merge or editing actions. Comparison settings can ignore letter 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 PDF, DOCX, XLSX, and PPTX files for comparison. Version 2.2 is dated September 23, 2026. NextDiff is freeware for personal and commercial use on Windows 10 and 11, with direct installer links and no account or email requirement.
