About this tool
This browser-based PDF privacy tool runs locally. Drag over sensitive areas, draw a signature, and export a new PDF.
Common uses
- Cover identity numbers, phone numbers, addresses, and other sensitive details.
- Add a simple handwritten signature to contracts, forms, or quotes.
How to use it
- 1.Choose a PDF and switch to the page you need.
- 2.Drag redaction boxes over sensitive areas, draw a signature, and place it on the current page.
- 3.Export and download the processed PDF.
Limits and notes
- The export rasterizes each page so the original text layer is not copied into the output; text, forms, and annotations are no longer editable.
- Processing stays in this browser; very large PDFs may be limited by device memory and page-pixel limits.
Frequently asked questions
Is the redacted content really removed?
Each page is rasterized during export, so the original PDF text layer is not copied into the output. Still review the downloaded file and keep the original secure.
Is my signature uploaded?
No. The PDF and signature are processed only in this browser and are not sent to a server.
