What it is

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.

Who it suits

DocFather suits readers who need to compare content changes between PDF or DOCX versions. It is less suited to reviewing formatting changes, and scanned documents need OCR before comparison.
