Screenshots that keep your secrets
Capture any area of your Mac screen, mark it up, and cover emails, keys and card numbers so they can’t be recovered.
Coming soon to the Mac App Store. One-time purchase, no subscription. Requires macOS 14 or later.
What you can do
Capture
Press your shortcut and drag over any area. The screen freezes while you choose, so menus and tooltips stay put.
Annotate
Arrows, lines, boxes, ellipses, text and numbered markers that renumber themselves when you delete one.
Redact
Pixelate, blur or block out anything sensitive with one drag.
Share
Copy with ⌘C, save as PNG or JPEG, or drag the image straight into Mail, Slack or Finder.
Hidden means hidden
Many tools lay a blur on top of your image. Mosaicshot paints the redaction into the pixels of the file it exports, so the original pixels of that area are simply not in it.
Pixelate and blur keep only a few coarse, noise-shifted blocks, sized to resist depixelation tools. For the most sensitive data, use a solid block: it keeps nothing at all.
