Clearance desk

You need to show someone the screen. You do not need to show them all of it. Paint over what should not travel, number what should, then export a PNG whose pixels have genuinely changed. Nothing leaves this tab — no upload, no server, no storage.

Nothing sealed yet.

    Nothing sealed yet Every stroke and callout you add gets logged here, in order, with the share of the frame it covers.
    How this works
    Pixelate
    Averages the real pixels into blocks. The detail is gone from the file, not hidden behind a filter.
    Blackout
    Paints an opaque bar. Use it when even the shape of the thing is too much.
    Add callout
    Tap the image to drop a numbered marker. Drag it, or focus it and nudge with the arrow keys. Backspace removes it.
    Hold to compare
    Press and hold to reveal the original. Release to snap back.
    Open / Paste
    Load your own screenshot from this device, paste one with ⌘V or Ctrl+V, or drop a file onto the plate.
    Export
    Downloads a flattened PNG — redactions and callouts baked in, original pixels unrecoverable.

    Brush painting needs a pointer — mouse, pen, or finger. Callouts are fully keyboard-operable. Your image is decoded and edited in this page's memory only; it is never sent anywhere, never written to storage, and disappears when you close the tab.
