How to Use

Open a PDF — drag and drop or click to upload any PDF. The tool renders it page-by-page in your browser.

Pick a tool — select Text (T), Highlight, Rectangle, Ellipse, Line, Arrow, Freehand, or Whiteout from the toolbar. Customize color, stroke width, and font settings in the options bar.

Annotate — click or drag on the page to add annotations. Navigate between pages with the Previous/Next buttons or arrow keys. Use Ctrl+Z to undo.

Save — click "Save PDF" to download the annotated file. All annotations are permanently baked into the PDF.

FAQ

Are my edits saved permanently? ▾

Yes. When you click "Save PDF", all annotations are permanently embedded into the PDF using pdf-lib. The downloaded file contains the original content plus your edits. The original file on your device is unchanged.

Does this tool send my PDF to a server? ▾

No — everything happens in your browser. Your PDF is never uploaded anywhere. The tool uses pdf-lib and PDF.js, both open-source JavaScript libraries that run entirely client-side.

Can I edit existing text in the PDF? ▾

This tool adds annotations on top of existing content — it does not let you modify or reflow existing text. To cover text, use the Whiteout tool and then add new text on top of it. For full structural editing, a desktop PDF application is needed.

What annotation types are supported? ▾

Text (with font size, bold, color), Highlight (semi-transparent yellow), Rectangle, Ellipse, Line, Arrow (with arrowhead), Freehand drawing, and Whiteout (white fill to cover content). All are saved permanently to the PDF.
