Stamp arbitrary text on a PDF page — pick content, anchor, size, weight and color. All processing is local; your file never leaves your device.

Add Text to PDF stamps arbitrary text onto one page of a PDF. You choose the text (including line breaks), the 1-based page number, a nine-position anchor or absolute x/y coordinates, plus font size, weight, color and margin. pdf-lib writes the text into the page content inside a Web Worker, so the file never leaves your device.

How it works

No rich text, rotation or automatic wrapping beyond the line breaks you enter
Modifying a digitally signed PDF can invalidate its existing signature

FAQ

Frequently asked questions

Can I add text to every page?

One run stamps one page. For repeating labels or headers, use Add Watermark (all pages) or run this tool once per page.

Why does my non-Latin text not appear?

The tool embeds the standard Helvetica font, which covers Latin characters. Complex scripts need a custom embedded font, which is not part of this tool.

Is the text editable after saving?

No. The text is written into the page content stream, so it becomes part of the page like printed text rather than an editable form field.

Is my file uploaded?

No. The edit happens in a Web Worker on your device. Neither the PDF nor the text is sent to a server.
