Is drawing a black rectangle in preview software the same as true redaction?

No! Simply drawing a black rectangle or highlight over text leaves the underlying text searchable and copyable. Drop & Clean performs true redaction, permanently deleting underlying characters and metadata.

Do I need to install software or plugins?

No. Drop & Clean runs immediately inside any modern web browser on Mac, Windows, Linux, and Chromebooks without installation.

Is Drop & Clean free to use compared to Adobe Pro?

Yes. Drop & Clean is free to use with complimentary credits, saving you hundreds of dollars in annual Adobe Creative Cloud subscription costs.
