Frequently Asked Questions

Is it safe to merge PDF files with this tool?

Yes, absolutely. All processing executes locally inside your web browser using WebAssembly and client-side JavaScript. Your files are never uploaded or stored on any server.

Can I reorder the PDF files before merging?

Yes. You can use the up/down arrows or simply drag and drop the files in the list to achieve your exact desired sequence before merging.

Does merging reduce document quality?

No. The merger extracts and combines the original pages and embedded vectors losslessly, keeping fonts, text clarity, and images at their original quality.

Can I merge password-protected PDFs?

If a PDF is encrypted with a password, you must first unlock it before merging. Encrypted files cannot be combined directly for security reasons.

Do you add any watermark to merged files?

No. PDF SaaS never adds watermarks, branding, or page limits to your documents. The output is 100% clean and free.

Can I merge PDFs on mobile devices?

Yes. Our tools are fully responsive and work seamlessly on mobile browsers on iOS and Android with no app installation needed.
