Frequently asked questions
What order will the merged PDF use?
Files are combined in the order shown in the workspace, and pages within each source PDF keep their original order. Use the Move up and Move down buttons before merging.
Are my PDF files uploaded?
No. These tools process the files in your browser. Gencyh does not receive or store the selected file contents. Close the tab or use Reset to clear the workspace.
Can I use a password-protected or digitally signed PDF?
Password-protected and encrypted PDFs are not supported. Editing a digitally signed file can invalidate its signature. Use an unsigned copy and keep the original.
