What XKit Document Compare is
XKit Document Compare is a free web tool for comparing Word, PDF and text files to identify additions, deletions and modifications. It presents the original and changed documents side by side, highlighting additions in green and deletions in red. Word-by-word comparison is intended to catch small edits within paragraphs. Users can upload files or paste text, and supported formats are DOCX, DOC, text-based PDF and TXT; documents in different formats can be compared. The product page says Word files and PDFs are processed in the browser using Mammoth.js and PDF.js to extract text, and that files are not uploaded. The privacy policy says inputs, files and processed data are not collected or stored, though anonymous website usage information and cookies may be used. The tool compares text rather than formatting, so font, color, bold and italic changes are not shown, and it does not produce redline output. Scanned or image-only PDFs need OCR before comparison. Tables and lists are extracted as text, which may not preserve their structure, and documents over 100 pages may take longer.
