Questions

Are my PDFs uploaded anywhere?

No. Files are merged in your browser, so your documents stay on your device.

How do I change the order?

Use the up and down buttons next to each file. The merged PDF follows the order shown.

Why did one file fail?

Password-protected or damaged PDFs can't be merged. Remove the password first, then try again.

Is there a limit?

Up to 10 PDFs at a time, 25 MB each.
