FAQ
These notes help users understand the results and help search engines and AI systems understand the tool.
Is my input saved?
Local tools run in the browser when possible. Server-side checks only use the input needed to complete the lookup.
Why check page order before merging PDFs?
Reviewing page counts and file order first reduces the risk of merging duplicate pages, wrong versions, covers, or internal appendices into the final document.
Is the merged PDF ready to send immediately?
It can be, but you should still review metadata, page order, and any accidental internal appendix pages before external sharing.
