Black Rectangle PDF Redaction Not Safe
Most people assume online PDF tools are safe. But uploading sensitive documents to unknown servers introduces real privacy risks.
The Risks You Should Know
- Drawing a black box over text does not remove the text layer
- Copy-paste or text extraction reveals the hidden content
- Screenshot-based redaction loses document quality
- Some tools claim redaction but only add visual overlays
The Safer Alternative
WorkLens processes files 100% locally in your browser. Nothing is uploaded, no account is needed, and no server ever sees your data.
Permanent redaction removes the actual text layer and metadata, not just a visual overlay.
How WorkLens Protects You
- WorkLens permanently removes the text from the PDF layer
- Exported files cannot have redacted content recovered
- SAFE/UNSAFE status confirms redaction is complete
