FAQ

Merge PDF questions

How do I merge PDF files?

Add two or more PDF files, arrange them in the order you want and select Merge PDFs. Occursa combines the files into one PDF and downloads it to your device.

Can I change the order before merging?

Yes. Drag PDF files into a new order on desktop or use the up and down controls on any device before creating the merged document.

Are my PDF files uploaded?

No. This merger processes supported PDF files locally in your browser, so your selected documents do not need to be uploaded to Occursa for merging.

Can I merge PDFs on my phone?

Yes. The tool is designed for modern mobile and desktop browsers, so you can select PDF files from your phone and merge them directly on the device.

Why can an encrypted PDF fail to merge?

Password-protected or encrypted PDFs may prevent browser-based merging. Remove the password protection first, then add the PDF again.
