Redacted Document for Mac

What Redacted Document does

Draw masks over chosen details
Draw a rectangle or ellipse over a name, number, face or other detail. New masks start as opaque black.
Choose black, pixelation or blur
Use another solid colour, pixelation or one of three blur effects instead of black.
Move, resize and group masks
Move and resize each mask with handles or controls. Repeat and group related masks.
Undo changes while you adjust
Undo or redo adjustments as you work. Change the strength of each mask at any time.
Compare before you save
Compare the finished image with your original in a split or side-by-side view, or inspect individual pixels at 1:1.

Step 4 of 4
Save a separate file
Save the reviewed image as a new file. An existing file is not overwritten.

Does it change my original files?

No. The original image remains untouched, and the covered copy is saved as a new file.

Does it detect details for me?

No. You decide what to cover. The app does not detect what needs hiding.

Does blurring guarantee anonymity?

No. Blurring or covering information does not guarantee anonymity. Inspect every area before sharing.

Can it work on PDFs or many images?

No. There is no native PDF editing and no batch processing. Work on one still image at a time.
