Frequently asked questions
Can this find every difference in a PDF?
Visual results compare pixels under the same PDF render settings, while text results follow the PDF's stored extraction order. Review both; the tool does not determine document equivalence.
What happens when pages are inserted or reordered?
Pages initially match by physical page number. Review added or deleted pages, then optionally assign each page at most once in manual mapping and compare again.
Are PDF files uploaded to a server?
No. Opening PDFs, rendering pages, extracting text, and creating reports happen in the current browser without modifying the source files.
