About this tool
Cover and annotate PDFs with three simple tools: colored rectangles to hide content, PNG images (like logos or signatures) to overlay, and text to add annotations. Everything runs in your browser — your PDF never leaves your device.
FAQ
Is my PDF uploaded to a server?
No. All processing uses pdf.js and pdf-lib running locally in your browser. Your document never leaves your device.
Are the overlays permanent?
Once you download the PDF, the rectangles, images, and text are permanently embedded into the document.
