How does PDF Compare detect differences between two document revisions?

The comparison engine performs dual-layer analysis: visual raster diffing (highlighting pixel changes in red/green) and text token stream comparison (identifying added, deleted, or modified words).

Can I compare multi-page contracts and legal agreements side by side?

Yes. Upload the original revision (Version A) and modified revision (Version B) to generate a page-by-page side-by-side comparison report.

How are text additions and deletions highlighted in the comparison report?

Inserted text is highlighted in green, deleted text is marked with red strikethrough, and modified passages are flagged with revision callout notes.

Can PDF Compare detect subtle changes in numbers or contract dates?

Yes. Exact token analysis catches single-character modifications (such as altered pricing, dates, interest rates, or clause numbers) across hundreds of pages.

What format is the comparison report exported in?

The comparison report exports as a standardized PDF audit document containing an executive summary of changes and visual diff pages.
