FAQ
Are my PDFs uploaded anywhere?
No. Merging uses pdf-lib running entirely in your browser. Your documents never leave your device — confidential contracts and statements stay private.
Is there a file size or page limit?
No hard limit — everything depends on your device's memory. Hundreds of pages per file work fine on a modern computer.
Need only some pages instead?
Use the companion Split PDF tool to extract a page range like 1-3,5 into a new file.
