Frequently Asked Questions

Q.Can I choose the page order before merging PDFs?

Yes! The tool merges documents in the exact order they are listed in your uploads dashboard. You can clear and add them in your desired sequence to arrange pages.

Q.Is there a limit to how many PDF files I can merge?

No hard limit! You can merge 2, 5, or 10+ PDFs at once. For exceptionally large files, ensure your computer has sufficient browser memory (RAM) available.

Q.Will merging PDFs affect hyperlinks or annotations?

No. The pdf-lib engine performs deep page copies, which preserves vector annotations, form fields, page rotations, text layers, and links from each source document.
