Merge PDF FAQ
Good to know
Will image quality and selectable text remain?

No. Remove the password or encryption with a trusted tool before adding the PDF.
What PDF features may not be preserved?
The tool copies page content but does not guarantee original passwords, signatures, bookmarks, attachments, JavaScript, forms, or document metadata.
What are the merge limits?
Add 2 to 20 PDFs, up to 100 MB in total and 500 pages. The same file can be added more than once.
