Frequently asked questions
How many PDFs can I merge?
Select at least two PDF files. Practical limits depend on available device memory and the size of the files.
Are the original PDFs changed?
No. The tool creates a separate merged PDF download and does not overwrite your source files.
Why might a PDF fail to merge?
A damaged, password-protected, or unusually structured PDF may not load. Try an unlocked, valid PDF copy.
