FAQ

Can I use overlay two pdfs without uploading my document?

Yes. Processing takes place in your browser, and the selected file is not sent to a Callpdf server.

What kinds of PDF files work with Overlay Two PDFs?

The tool supports standard PDF files readable by the browser library. Damaged PDFs, XFA forms, and unusually complex documents may not work.

Will this tool preserve links and selectable text?

The tool edits PDF page objects where possible, so normal text and links are generally retained. Content outside a crop boundary may become hidden.

Can I process an encrypted or password-protected PDF?

Remove the password in software you trust before using this page. This browser tool does not bypass PDF encryption.

What should I do if the PDF is very large?

Try a smaller file or split the document first. Browser memory limits vary by device, especially on mobile.
