Features Overview

File comparison

GroupDocs.Comparison allows you to detect differences between source and target files for changes at paragraphs, words, and characters levels. It can identify styling and formatting changes like bold, italic, underlines, strike-troughs, font types, etc.

Apply/Reject changes between documents

Every difference between compared documents can be applied or rejected and then exported to the output document.

Document information extraction

GroupDocs.Comparison allows obtaining basic information about source documents - file type, size, page count, etc. For example, you can use this to generate previews of compared documents.

Comparison summary report

Once the comparison process is complete, you can save a differences summary report that lists all changes in compared documents.
