Frequently Asked Questions

How do I put two PDF pages side by side?

Upload your two PDF files using the upload areas above, choose a page size option, and click Merge. The tool combines them horizontally — page 1 of the first PDF appears next to page 1 of the second — and downloads the result automatically.

Can I merge PDFs without Adobe?

Yes. This tool requires no software installation and no Adobe subscription. It runs directly in your browser and is completely free.

Is there a free PDF merger with no upload?

Yes — this tool. All PDF processing happens in your browser using JavaScript. Your files are never sent to any server, so no upload ever occurs.

What happens if my two PDFs have different page counts?

The tool handles unequal page counts automatically. If one PDF has more pages, the extra pages are included on one side with a blank page on the other.

Does this work on mobile?

Yes. The tool works on Chrome, Firefox, Safari, and Edge on both desktop and mobile devices.
