Another You and Cleanor
These sections explain the job in plain language and set expectations for what the tool should do well.
Sometimes the safest answer is also the simplest: cover the sensitive part completely. A black box communicates immediately that the content is intentionally hidden and should not be inferred.
That makes it useful for documents, screenshots, payment screens, admin interfaces, and any export where the masked area should be unquestionably unreadable.
This is best for people who already know they want black-box redaction and do not need the extra step of choosing between multiple masking styles.
Short answers for the questions people usually have before trying a utility like this.
A black box is stronger and more explicit. It fully covers the selected area instead of only softening it.
No. This variant is intentionally fixed to black-box redaction so the workflow stays focused on one job.
Yes. The image is redacted and exported in the browser without server-side processing.
