Are my files uploaded to a server?

No. Every tool on this site runs inside your browser. Your file is read from your disk into your own browser's memory, processed there, and written back out. You can confirm this yourself: open your browser's developer tools, switch to the Network tab, and run the tool — you will not see your document being sent anywhere. It also means the tools keep working if you go offline after the page has loaded.

Can I edit the text that is already in the PDF?

No, and it is worth explaining why. A PDF stores text as positioned glyphs, not as editable paragraphs, so changing an existing sentence means re-flowing everything around it — which is why full text editing is a paid desktop feature almost everywhere. This tool adds new content on top, which covers the great majority of what people actually need.

Can I cover something up with a white box?

You can, but do not use it to hide sensitive information. The content underneath is still in the file and can be recovered. Redact PDF removes it properly.

When you would use this

Most PDF editing is annotation rather than rewriting: filling in a form that has no real fields, marking up a drawing or a proof, adding a note before passing a document on, circling the paragraph someone should read, or putting a logo on a page. Doing it in the browser avoids both a desktop editor licence and uploading the document.
