Can I edit existing text in a PDF?

This tool adds new text on top of the existing PDF content. Directly editing embedded PDF text requires access to the original fonts and encoding, which is not possible in a browser. To replace text, you can cover the original with a white box and add new text over it — a technique used by most web-based PDF editors.

Is my PDF uploaded to a server?

No. Your PDF is opened and processed entirely in your browser using PDF.js and pdf-lib. Nothing is uploaded to any server. Your file never leaves your device.

What fonts are supported?

The tool supports four standard PDF fonts: Helvetica, Helvetica Bold, Courier (monospace), and Times Roman. These are built-in PDF standard fonts that do not require embedding, keeping file size small.

How do I add text to multiple pages?

Use the page navigation arrows in the toolbar to move between pages. Text boxes are placed on the page currently in view. All annotations across all pages are saved when you download.
