Merge PDF — frequently asked questions
How many PDFs can I merge at once?+
There is no fixed limit. The practical ceiling is your device memory. Dozens of ordinary documents are routine; hundreds of large scans are better done in batches.
Does merging reduce PDF quality?+
No. A correct merge copies each page object into a new document without re-encoding images or text. Your pages remain identical to the originals.
Can I merge password-protected PDFs?+
You need to unlock them first. Password-protected PDFs cannot be read until the password is removed.
