FAQ
How many files do I need?
At least two. With only one you will see "Choose at least two files".
How do I control the order?
Files are merged in alphabetical order of their names, with numbers sorted naturally (2 before 10). To control the order, number the file names (1-cv, 2-certificate) and select them again.
Can I merge a password-protected PDF?
No, protected files cannot be opened. If the file is yours and you know the password, remove the protection in your own PDF app first.
Do I need to install anything?
No. The first run loads the pdf-lib library from a public CDN; after that everything happens on your device.
