Frequently asked questions
Is the PDF merger really free?
Yes. Merging PDFs is 100% free with no limits, no hidden fees, and no premium tier for essential features. The site is supported by advertising.
Are my files uploaded to a server?
No. All processing happens locally in your browser using JavaScript. Your PDFs never leave your computer, which makes the tool safe for confidential documents.
Can I merge PDFs that are password protected?
Encrypted PDFs with an owner password can usually be merged. Files protected with a user (open) password must be unlocked with their password first.
What is the maximum file size?
There is no artificial limit, but very large files require more memory from your device. Files of up to a few hundred megabytes work well on modern computers.
Will the merged PDF have a watermark?
No. The output file is clean and contains no watermark, footer, or branding of any kind.
