How it works
- Select the two PDFs to compare together.
- Choose the page and shared zoom.
- Review both versions side by side with coordinated scrolling.
PDFs without passwords or digital signatures. Standard forms are supported in the Fill PDF forms tool. Maximum 3 minutes per operation.
Does it highlight differences automatically?
This version offers a manual visual comparison. It does not automatically identify or highlight changes to text or graphics.
Can documents have different lengths?
Yes. When a page exists only in one document, the other pane shows a warning.
Is a new PDF created?
No. This tool lets you view and compare the two documents in the browser; it does not produce a report or a modified file.
