Compare Two PDFs
Load an original and a revised PDF, move page by page, swipe between versions and highlight visual differences without uploading either document.
How should I read the comparison views?
The wipe view places version B over version A and lets you reveal either side with a slider. It is best for layout, image and pagination changes. The difference map emphasizes pixels that changed, making small shifts, deleted text or replaced graphics easier to spot.
What does the downloadable report contain?
The report places the corresponding page from file A and file B side by side. It is useful for review meetings, approval records and manual quality checks. It is a visual report, not a semantic legal-document comparison.
Best uses
- Compare revised contracts or proposals before approval.
- Check exported designs after a layout update.
- Review scanned forms for changed handwriting or stamps.
- Verify pagination, logos, images and repeated headers.
Frequently asked questions
Does the tool compare text meaning?
No. It performs a visual page comparison. It can reveal changed pixels and layout, but it does not interpret legal meaning or grammar.
What happens when the PDFs have different page counts?
The comparison continues to the longer document. Missing pages are shown as blank on the shorter side.
Can I compare scanned PDFs?
Yes. Visual comparison works well with scans because it compares rendered pages rather than relying on selectable text.
Why do tiny alignment shifts create many differences?
A small page shift changes many pixels. Use the wipe view to decide whether the difference is a real content change or only alignment.
Is the report searchable?
The visual comparison report is image based. Keep the original PDFs for searchable text.
Are the two files uploaded?
No. Both PDFs are rendered and compared locally in your browser.
