Merge PDF FAQ
How many PDF files can I merge?
You can select two or more PDF files. Practical limits depend on total file size, your connection and the backend service.
Can I change the merge order?
Yes. Use the up and down buttons beside each file. The first file in the list appears first in the merged PDF.
Why did my merge fail?
A PDF may be password-protected, damaged, too large or invalid. A connection or server problem can also interrupt the merge.
Will the pages keep their original quality?
PDF merging normally joins existing pages rather than recreating them. The final result still depends on the backend and the source files.
Can I merge protected PDFs?
Password-protected files may fail unless they are unlocked first. Only remove protection when you have permission.
How are my files processed?
The selected PDFs are uploaded to Toolerd's backend service and combined there.
