When the whole screenshot is the secret — not one field inside it — cover the frame with opaque black and export.

This page is for full-frame blackout — when the entire image is the secret, not a single field inside an otherwise shareable photo. A classified slide, a full bank-app screenshot, a complete ID card, a medical portal dashboard: there is no “safe background” to keep. Sibling black out part of an image is the targeted-region job. Stay here when the honest redaction is an opaque sheet over the whole canvas, or over so much of it that you are really publishing a redacted rectangle, not a picture with a box on it.
Security teams sharing a reproduction screenshot often need the UI chrome gone, not just one token. Journalists publishing a leaked dashboard may keep a single chart title and black the rest. Parents sending a school form photo may black the entire card except a checkbox. Full-image blackout is also the right move when you cannot inventory every identifier in time — a bus-side screenshot of a monitor — and policy says “if in doubt, cover it all.”
Leaving a one-pixel gutter. Recipients zoom. A strip of desktop wallpaper or a clock is enough to place the screenshot.
Blacking the body and keeping the browser tab title. Tab titles reprint the patient name or the ticket ID.
Using blur on a full ID card “so it still looks like a document.” That is not this page’s job. Opaque black is the point of full-image redaction.
To blackout an image online in the full-frame sense is to treat the file as contraband until proven otherwise. HideShot’s Black Box mode overwrites pixels. There is no recoverable photo under a completed full-canvas rectangle.
Use this when a screenshot of an entire EMR row, a crypto seed-phrase screen, or a passport photo must leave your machine as a black rectangle with maybe one approved label. For covering one SSN inside a photo you still want to publish, use black-out-part-of-image instead.
Stack is optional here. One rectangle from corner to corner is the usual move. Undo if you covered a caption you were required to keep, then redraw.
When there is no safe remainder — full ID cards, entire bank-app screens, classified slides, or dashboards where leftover chrome still identifies a person or system.
Sometimes the point is to show that a file existed and was withheld, or to keep one approved caption. If you need the rest of the photo, you wanted targeted blackout, not this page.
Not from the downloaded PNG if the box covered the pixels. Always check the edges and the tab chrome.
No. HideShot edits raster images. For PDFs use HidePDF. Print-screen a PDF page only when you must share an image, then black the frame here.
