Choose two PDFs to compare text changes and document properties locally.
Download the Letter source and its A4 version. Compare the Letter source with its A4 version: wording should match while page dimensions differ. This does not test visual pixel changes.
How to use Compare PDFs
Choose the earlier and revised files
Text is compared at matching source page positions; inserted pages can shift later comparisons.
Compare PDFs
Keep the source, run the task and inspect the result before accepting it.
Read differences in context
Review the displayed pages or report against the source document.
Review wording changes between two PDF versions
Compare two PDFs page by page for extracted-text changes, with side-by-side results. Free local processing; no visual pixel comparison.
A practical example
Choose the earlier version first and the revised version second. Inspect added and removed text on corresponding page numbers.
What to check in the result
A newly inserted page can shift later comparisons. Scans need OCR, and image-only or layout changes are not a visual difference report.

Questions & answers
Does this compare images or automatically align shifted pages?
No. It compares extracted text at corresponding file page positions and reports some metadata and page-size changes. Review images and shifted pages manually.
