Question 1

Are my files uploaded to a server?

Accepted Answer

No. The PDFs are read and rebuilt in your browser with JavaScript. Nothing leaves your device, which is why the tool also works offline once the page has loaded.

Question 2

Is there a page or file limit?

Accepted Answer

Each file must be under 50MB. There is no fixed page limit, but very large documents take longer to render thumbnails because that work happens on your own machine.

Question 3

Does rotating a page re-encode it?

Accepted Answer

No. Rotation sets the page's rotation property, so the original content is copied across untouched and no quality is lost.

Question 4

Can I add a seal or signature here?

Accepted Answer

Not on this page — use the PDF stamp tool for that. A common workflow is to merge or split here first, then stamp the result.

Question 5

Why does the free download have a watermark?

Accepted Answer

Free exports carry a light watermark across each page. A Pro subscription removes it; the page arrangement itself is identical either way.
