FAQ
Do permissions guarantee viewers cannot copy or print?
Password protection is embedded into the PDF, but permission flags still depend on viewer support.
Is this tool private?
Yes. For this workflow, file processing happens securely and the document is not uploaded to ScrollPDF during the tool operation.
What file size limit applies?
ScrollPDF currently validates files up to 100 MB per file in the browser UI.
Why can the output look different from the source file?
PDF structure, fonts, compression, form fields, and embedded assets vary between files, so exported results can differ slightly depending on the operation and the original document.
Do I need to create an account to use this tool?
No. Core ScrollPDF tools remain available without an account. Accounts are for profile, auth, and future saved-file features.
