The report is a visual pixel comparison. Font rendering and antialiasing can produce small highlights even when the underlying text meaning is unchanged.
Compare PDF: how it works
PDF Care renders both documents locally at a controlled resolution, compares matching page pixels and creates a side-by-side PDF report showing PDF A, PDF B and highlighted differences.

Questions about Compare PDFs
Are files uploaded when I use Compare PDFs?
No. PDF Care processes this tool locally in your browser, so the document contents are not uploaded to a PDF Care application server.
Does Compare PDFs compare text meaning?
No. This first version performs a visual page comparison so layout, images and rendered text changes can all be highlighted.
What if the PDFs have different page counts?
Extra pages are treated as visual differences and are included in the generated comparison report.
