Frequently Asked Questions
How many PDF files can I merge?
Up to 20 PDF files per merge operation. You can arrange them in any order before combining.
Is there a file size limit?
Each individual PDF can be up to 100MB. The total merged output depends on your browser's available memory.
Will merging affect PDF quality?
No. The merge operation copies pages directly without re-encoding. All original formatting, images, text, and vectors are preserved exactly.
Can I rearrange the order of PDFs?
Yes. After uploading, use the up/down arrow buttons to arrange documents in your desired sequence before merging.
Are password-protected PDFs supported?
Currently, the tool cannot merge password-protected PDF files. You would need to unlock them first.
Does the merged PDF retain bookmarks?
The current implementation preserves page content but may not retain bookmarks, forms, or interactive elements from source PDFs.
