FAQ

Frequently asked questions

Q Is this PDF merger really free with no watermark?

Yes, completely free and no watermark is ever added. You can merge PDFs as many times as you need without creating an account or paying anything.

Q Are my PDF files uploaded to your servers?

No. All merging happens entirely inside your browser using JavaScript. Your files are never sent to any server, ensuring complete privacy.

Q What is the maximum file size supported?

There is no strict server-side limit since processing is browser-based. Files up to 50MB each work well in most modern browsers. Very large files may slow your browser.

Q Will the merged PDF lose quality or formatting?

No. The tool combines the original pages without re-encoding them, so fonts, images, and layouts remain identical to the source files.

Q Does this work on mobile phones and tablets?

Yes. The tool works in any modern browser on desktop, tablet and mobile. You can merge PDFs from your phone without installing any app.

Q Can I merge password-protected PDFs?

Password-protected PDFs cannot be merged directly. Remove the password protection first before uploading the files to this tool.
