FAQ

Can add corner labels to pdf be processed without uploading my PDF?

Yes. This page processes the selected file inside your browser. The PDF is not sent to Callpdf.

Does Add Corner Labels to PDF work with password-protected PDFs?

No. Remove the password in an authorized PDF application before using this browser tool.

What happens with scanned PDF pages?

Scanned pages are retained because this tool edits or renders whole PDF pages rather than relying on selectable text.

Can I process a large PDF with this tool?

Browser memory varies by device. Start with a limited page range for large or image-heavy documents and keep this tab open until processing ends.

How should I verify the downloaded result?

Open the downloaded file and inspect several pages, including the first, last, and any range boundary pages, before sharing it.
