In their own words
DocFather Compare Documents
DocFather Compare Documents is a web tool for comparing the content of two document versions. It aligns text and marks additions in green and removals in red, with edited lines identified down to the word. Its PDF tool compares two PDF files, while its Word tool compares DOCX content without requiring a Word license or Track Changes.
The comparison covers content changes such as paragraphs, sentences, numbers, and dates, but skips formatting-only differences. For pairs in different formats, the service recommends converting Word to PDF first; scanned files need OCR to add a text layer. The comparison tools are described as free, and the pricing page lists free file tools for files up to 300 MB, while a separate maximum file size is 50 MB. New web accounts receive 250 welcome credits. A 7-day free trial is available in the iOS app, while web users subscribe directly. Files are uploaded over an encrypted connection and automatically deleted from storage within 24 hours.
SmarterDiff
SmarterDiff is a free browser-based tool for comparing text, Word documents, PDFs, spreadsheets, folders, and images. Text comparisons can show line, word, or character differences, with options to ignore case and whitespace. Excel and CSV comparisons check cell values and formulas, while image comparisons use pixel differences with overlay, side-by-side, and slider views. It can compare finalized.docx text, but not Word tracked-change markup; scanned PDFs without embedded text cannot be compared as text. SmarterDiff says comparisons run in the browser and files or results are not sent to its servers or external services. Comparisons can work offline after the first page load while browser libraries remain cached. File size depends on available computer memory and browser limits. It is a manual, one-off tool without workflow automation or integrations. The Free plan costs nothing, is ad-supported, requires no account, and has no artificial limits.
