Frequently Asked Questions
Is the redacted text completely unrecoverable?
Yes. When choosing 'Solid Blackout Box' or heavy Gaussian blur, the underlying canvas pixels are completely overwritten destructively before downloading.
Can I draw multiple censor boxes?
Yes. Simply click and drag across any area of the photo to create multiple censorship zones.
