How to merge multiple PDF files into one

Frequently asked questions

Is there a limit on how many PDFs I can merge?
There is no hard limit. Very large combined files just take a little longer to process in the browser.
Will merging change the quality of my PDFs?
No. Merging copies the original pages as-is, so text and images keep their original quality.
