HAPX Merge

Files stay on your device. Nothing is uploaded.

Merge PDF files without uploading them

Combine as many PDFs as you like into one document. Add your files, put them in the order you want, then download the result. Every step happens inside this browser tab, so your documents stay on your device and are never sent to a server.

No files added yet. The finished document follows the order shown here, top to bottom.

How to combine your PDFs

Drop your files onto the panel above, or select them from your computer. Each file appears in a list showing its page count, so you can check you have the right documents before you go any further. Drag a row to move it, or use the arrows if you are on a phone. The finished document follows that order exactly, top to bottom. Give it a name, press merge, and the combined file downloads to wherever your browser saves things.

Why your files stay on your device

Most free PDF tools work by sending your document to a server, doing the work there, and sending it back. That is fine for a shopping list and a genuine problem for a signed contract, a payslip or a medical letter. HAPX Merge takes a different route. All of the processing runs in your browser using the device you are already sitting at, which means there is no upload, no copy of your document sitting on someone else's hardware, and nothing to delete afterwards. Once this page has loaded you can disconnect from the internet entirely and it will still work.

Common questions

Are my PDF files uploaded to a server?

No. Everything happens inside your browser, so your files stay on your device and are never sent anywhere.

Is there a limit on how many PDFs I can combine?

There is no set limit. Because the work happens on your own device, the only practical limit is the memory available to your browser. Very large files may take a few seconds longer to process.

Does it cost anything or add a watermark?

It is free to use and adds no watermark. There is no sign up, no account and no daily limit on the number of documents you can create.

Can I change the order of the files before merging?

Yes. Drag any file into position, or use the up and down arrows on each row. The finished document follows the order shown on screen.

Can it open password protected PDFs?

Not currently. Remove the password from the file first using the application that created it, then add it here.
