Why pick Convertify for this?

Files stay on device

Convertify processes everything in your browser using JavaScript. Your file is never uploaded — confirm with DevTools → Network. That makes this safe for sensitive material like contracts, IDs, and financial documents.

No upload wait

Because nothing uploads, processing starts the instant you click. For typical files (under 50 MB) the whole job finishes in seconds — no progress bar, no queueing behind other users.

No daily quota

Free without limits, including no "3 conversions per day" cap that competing services impose. Run as many merge pdf jobs as you need.

No watermark

Your output is clean — no Convertify branding, no metadata stamp. Same as if you'd run a paid desktop app.

Frequently asked questions

How do I merge PDFs on Windows 10 for free?

Open Convertify in Edge or Chrome, drag your PDF files in, arrange the order, and click merge. The combined file downloads instantly with no software to install.

Does Windows 10 have a built-in PDF merge tool?

No. Windows 10 can open and print PDFs but cannot combine them natively, which is why a browser tool like Convertify is the simplest free option.

Is there a file size or page limit?

No. You can merge large documents and many files at once because processing happens on your own PC rather than a server.

Will merging add watermarks?

No. Convertify never adds watermarks, so your merged PDF looks clean and professional.

Are my files safe on Windows 10?

Yes. Files are processed locally in the browser and never uploaded, so your documents stay private.
