Add White Cover Blocks to PDF Online
This free online PDF whiteout tool lets you upload a PDF, draw white cover rectangles directly on the page preview, hide selected content, and export a new PDF file. It is useful when you want to visually cover names, phone numbers, addresses, amounts, remarks, IDs, or other content in a PDF without editing the original source document structure.
You can add multiple white cover areas across different pages, move them, resize them, and then export the final PDF in one step.
Common use cases
- cover text in a PDF with a white box
- hide sensitive data in contracts, forms, or invoices
- cover handwritten notes or old stamps in scanned PDFs
- edit screenshot-based PDFs or PDFs that are hard to modify directly
How it works
- Upload a PDF
- Drag on the page preview to create a white cover area
- Move the area or resize it from the bottom-right corner
- Add more white cover areas on any page
- Export the updated PDF
Privacy
PDF preview, whiteout area selection, covering, and export all run locally in your browser without uploading files to a server.
