Are my PDF files uploaded?

No. The document is opened and rewritten inside your browser. It is never sent to a server, and closing the tab discards it.

Does white-out delete the text underneath?

No. It covers it when the PDF is viewed or printed, but the text is still in the file. Use Redact PDF to remove text for good.

Can I change the existing text?

To replace a word or line, use Edit PDF Text. PDF Studio adds new items on top of the page.

Which languages and symbols can I use?

With the default Noto Sans font: Latin, Greek, Cyrillic, Vietnamese, Hindi and Marathi (Devanagari), and symbols such as the rupee sign. Only the characters you use are embedded. The Helvetica, Times and Courier options cover Latin text only. Emoji and other scripts are not supported yet.

Can I use a password-protected PDF?

Unlock it first with the Unlock PDF tool, using its password. Protected files cannot be processed directly.

What happens to digital signatures?

Any change to a signed PDF invalidates its digital signature. Treat the result as unsigned and keep the original.
