This guide shows a repeatable workflow to compare two pdfs and find differences (text changes, missing pages, revisions) using browser‑based tools. All processing happens locally in your browser (no uploads), which is especially useful for sensitive documents.

When you should compare PDFs
If you have ‘Final_v3’ and ‘Final_v4’, it is easy to submit the wrong file. Comparison prevents expensive mistakes.
What to look for
Check: missing pages, edited clauses, date changes, and layout shifts. For scanned PDFs, differences can be subtle—focus on key pages.
Workflow that scales
1) Compare the two versions. 2) If only specific pages changed, extract them and replace in your master file. 3) Merge into a single final PDF. 4) Compress if the portal has strict limits.
Version control tips
Use a naming pattern (YYYY‑MM‑DD + short descriptor). Keep a ‘submitted’ folder to avoid overwriting the final file.
Quick checklist (before you download)
- Open the output at 100% zoom and check the most important page.
- Confirm page order and page count are correct.
- If you will email or upload the file, verify size limits first.
- Keep a “submitted” copy unchanged once you send it.
