Frequently Asked Questions
Are my PDF files safe?
Yes! Your files are processed entirely in your browser using local resources. They are never uploaded to any server.
Can I number only specific pages?
Yes, you can enter a specific page range (e.g., 1, 3, 5-10) to only add numbers to those pages.
Does this ruin my selectable text?
No. The numbers are embedded natively as vector text, so your original PDF remains completely intact, searchable, and selectable.
