Frequently Asked Questions
Quick answers to common questions
Are my PDF files uploaded to a server?+
No. Merging happens entirely in your browser. Files never leave your device.
Can I reorder files before merging?+
Yes. Use the up/down arrows to change merge order. The numbered list shows final sequence.
How many PDFs can I merge?+
There is no fixed limit, but very large files depend on your device memory. Most users merge 2–20 files easily.
Do password-protected PDFs work?+
Encrypted PDFs may fail. Remove password protection first if needed.
Can I remove a file from the list?+
Yes. Click the X button next to any file to remove it before merging.
What order are pages merged in?+
Pages follow file order — all pages from file 1, then file 2, and so on.
Is this tool free?+
Yes. 100% free with no signup or watermarks.
Will formatting be preserved?+
Yes. The tool concatenates original PDF pages without re-rendering content.
