Concatenation FAQ Matrix
Can I merge encrypted PDFs?
Yes, but you must provide the password for each encrypted file to unlock it before merging can take place. This happens locally in your browser.
Will the quality be reduced during merging?
No. We copy the raw page data from source files to the new file, ensuring text remains sharp and images retain their original resolution.
Is there a limit to how many files I can merge?
No. Since processing happens on your device rather than our servers, there are no artificial limits beyond your system's memory.
