About this tool
When to use it
Review a revised proposal, report, or drawing against its earlier version. Visual comparison can help you spot changed words, figures, images, and layout without uploading either document.
What you get
Pages are paired by position: page 1 with page 1, then page 2 with page 2. Highlights show visible differences. Use the overlay view to inspect alignment, or download a side-by-side comparison report.
Before sharing
This compares rendered pages, not meaning, hidden data, or metadata. Inserted pages can shift later pairs, and scans can highlight small alignment differences. Review the source documents alongside the results.
