Frequently asked questions
Can I merge more than two PDFs?
Yes. Add two or more PDF files. The merged document follows the order shown in the workspace.
Are the source PDFs deleted?
No. The originals remain on your device. The tool creates a separate merged download.
Why did a PDF fail to merge?
A file may be damaged, encrypted, or too large for available browser memory. Try opening the file first or use a smaller copy.
