PDF Text Comparator
Compare text content of two PDFs page by page
About this tool
Compares the text layer of two PDFs page by page and shows added, removed, or changed text for review. It is useful for contract revisions, generated reports, and release checks, but it does not compare visual layout, fonts, images, annotations, or positioning. Processing stays in the browser.
Frequently Asked Questions
What does the PDF text comparator compare?
It extracts the text layer from both PDFs and compares corresponding pages for inserted, removed, or changed text.
Does it compare PDF page appearance?
No. Colors, fonts, spacing, images, annotations, and visual positioning are outside this text-focused comparison.
What if the two PDFs have different page counts?
The result identifies pages that exist only on one side and still compares the pages that have matching positions.
Can it compare scanned PDFs?
Only if the scans contain a usable text layer. Image-only scans need OCR before a text comparison can find words.
Is the comparison private?
Yes. Both files are read and compared locally in your browser without an upload request.
Is this useful for release or contract review?
Yes. It quickly highlights wording changes in generated documents, policies, contracts, and release artifacts.
