常见问题

How do I add text to a PDF?

Open our PDF Editor tool, drop your PDF, click on the page where you want to add text, type your text, customize font/size/color, click 'Save'. The text is embedded into the PDF and the file downloads. Runs in your browser, no upload needed.

Can I add text anywhere on the page?

Yes — our editor lets you place text boxes at any x/y coordinate on any page. Drag to position, resize with corner handles. Multiple text boxes per page supported. Useful for filling gaps in scanned forms, adding correction notes, or annotating content.

Will my original PDF content be modified?

No. Our tool adds your text on top of the original content without modifying it. The text layer is embedded at your chosen position over the existing PDF. For some operations (whiteout + rewrite), the underlying text is removed first, then new text added.

Is my PDF uploaded?

No. pdf-lib processes everything in your browser. Whether you're annotating confidential contracts, marking up exam papers, or adding notes to internal reports, the file stays on your device.
