Does PDF comparison detect every text change?

FlowPDF provides visual page comparison. It is useful for reviewing layout and visible changes but is not a forensic semantic diff or legal verification service.

Are both PDFs uploaded?

No. Both files are read locally in the active browser tab.

How to compare PDF files

Attach the original PDF and the revised PDF.
Move through corresponding pages and inspect the visual comparison.
Record or resolve differences using your normal review workflow.

What visual comparison can reveal

Page comparison can highlight changed wording, moved objects, altered images, different margins or missing content. Results are easiest to interpret when both files have matching page sizes and page order.

Important comparison limits

This tool is designed for practical visual review. It does not certify that two documents are legally identical, interpret meaning, compare hidden metadata or replace specialist document-review software.

Compare PDF questions

Can I compare PDFs with different page counts?

Yes, but shifted or inserted pages may make corresponding-page review less direct.

Does it compare metadata?

No. FlowPDF focuses on rendered page appearance rather than hidden metadata or document history.
