Frequently asked questions
Will merging change my PDF quality?
No. Pages are copied into the new document exactly as they are — text, images and layout are preserved at full quality.
How many PDFs can I merge at once?
There is no fixed limit. Because everything runs in your browser, the practical limit is your device's memory — merging dozens of normal-sized PDFs works fine.
Can I merge password-protected PDFs?
No. Encrypted PDFs must be unlocked first with their password in a PDF reader before you can merge them here.
Are my files uploaded anywhere?
Never. The merge happens entirely in your browser using JavaScript. Your files stay on your device from start to finish.
