Unlike simple overlay tools, CoverUP converts your PDFs to images before redaction. This ensures that hidden text layers cannot be extracted.
The original text is completely removed from the document, not just covered up. Your sensitive information stays private.
PDFs are converted to images, removing all hidden text layers and metadata.
Text cannot be copied or indexed without OCR, adding an extra security layer.
Fully transparent code on GitHub. Verify the security yourself.
CoverUP is free and open source. If you find it useful, consider buying me a pizza!
