Frequently Asked Questions
Is there a limit to how many files I can merge?
There are no artificial limits imposed by KR PDF. However, because processing happens in your browser, attempting to merge hundreds of massive files might be constrained by your device's memory.
Can I merge encrypted/password-protected PDFs?
Currently, our tool requires PDFs to be unprotected to process them. You will need to remove the password protection before merging.
Does merging files reduce their quality?
No. Our merger simply appends the pages together without compressing or altering the original contents, so there is absolutely zero quality loss.
