PDF Toolbox

Features

This free online PDF merger combines multiple PDF files into a single document, right inside your browser. Add the files you want, drag them into the order you need, and download the merged PDF in one click. Because the merging happens locally on your device, your documents are never uploaded to any server — which matters when the files are invoices, contracts, or anything private. There is no watermark and no sign-up.

Frequently Asked Questions

1. Are my files uploaded to a server?

   No. The merge runs entirely in your browser, so your PDFs never leave your device.

2. Is there a file size limit?

   There is no hard limit, but very large files depend on your device's memory since everything is processed locally in the browser.

3. Can I change the page or file order?

   Yes. Drag the files into the sequence you want before merging, and they will be combined in that order.

4. Will the merged PDF have a watermark?

   No. The output is a clean merged PDF with no added watermark or branding.

5. Can I split a PDF back apart later?

   This tool only merges. To break a PDF into pieces, use a dedicated PDF split tool.
