How to use Redact screenshot

What the tool does, how to run it, and what to expect from the result.

How to redact a screenshot properly

The safe moves are crop and opaque box. Crop removes the pixels from the frame; a box overwrites them. Both survive because the export is a new flattened file.

Blur and pixelate are available, but they belong on faces and avatars, not on text.

  • Upload the screenshot.
  • Crop first, cutting away any edge of the frame that does not need to be there at all.
  • Draw a black or white box over every readable identifier: names, account numbers, emails, tokens, addresses.
  • Use blur or pixelate only for avatars and faces, never for text.
  • Export as PNG, zoom to 100 percent and read the whole frame again before you share it.

Why screenshot redaction is usually a mixed workflow

One screenshot often contains different kinds of private details at once. A username may look best with blur, an account number may need a box, and the extra edges of the screen may be easiest to remove with crop.

That is why a broad redaction page should keep the full toolkit available instead of forcing one masking style for every situation.

Where this is most useful

This page works best when someone is preparing a screenshot for support, docs, social sharing, compliance review, or public publishing and needs flexibility without leaving the browser.

  • Bug reports and product support attachments
  • Knowledge-base and how-to screenshots
  • Internal dashboards and financial UI captures
  • Public sharing of app or web screenshots
Tips

Getting a better result out of Redact screenshot

Specific settings and thresholds, not general advice.

  • Only two of the five modes here are real redactions. The black box and the white box overwrite the pixels, and crop removes them from the frame entirely. Blur and pixelate transform the pixels and are reversible in principle, which is why they are the wrong choice for text.
  • Crop is the strongest option of all, because the pixels never make it into the exported frame. If the sensitive content is at the edge of the screenshot, cropping it away beats masking it every time.
  • The reason the boxes are safe here is that the export is flattened. The screenshot is rasterised into a canvas, the box is painted onto those pixels, and a completely new file is encoded, so the exported image has no layers and nothing hidden underneath.
  • That flattening is also what protects you from the class of bug where a screenshot editor writes a shorter file over a longer original and leaves the cropped-out data recoverable in the tail. A new blob is created from the canvas each time, so the file is exactly the pixels you see.
  • Work through the whole frame, not only the obvious field. Browser tabs, window titles, notification banners, autocomplete dropdowns, the clock, and the other half of a split-screen have all leaked more than the thing the person meant to redact.
Limits

What Redact screenshot does not do

The honest boundary, so you do not lose time finding it yourself.

  • It does not detect sensitive content. Every box, blur and crop is a rectangle you draw by hand.
  • Selections are rectangular. An L-shaped region takes two boxes.
  • It will not stop you from choosing blur on an account number, which is not a secure redaction.
  • It does not delete the original screenshot from your disk.

FAQ

Common questions

Short answers for the questions people usually have before trying a utility like this.

Can I mix blur, boxes, and crop on the same screenshot?

Yes. This variant keeps the full screenshot redaction toolkit, so you can stack multiple edit types before exporting.

Is this different from the main screenshot redactor page?

The editor is the same. This page is a specialized SEO entry point with screenshot-redaction-focused copy and metadata.

Does the cleaned file keep the original metadata?

No. Export runs through canvas, which preserves the visible image but strips common source metadata.

Which mode is an actual redaction?

The black box, the white box and crop. The boxes overwrite the pixels with a flat colour, and crop removes the region from the frame. Blur and pixelate are reversible transforms of the original pixels, and text hidden with either has been recovered by public tools.

Is the cropped-away part really gone from the file?

Yes. The tool draws the cropped region into a fresh canvas and encodes an entirely new file from it. There is no truncated original underneath, which is the flaw that made some phone and desktop screenshot editors leak cropped content a few years ago.

Can I mix modes on the same screenshot?

Yes. Every rectangle you draw is applied as an independent action, so you can black-box the account number, blur the avatar and crop the notification bar in one pass, then export once.

What do people usually miss?

Everything outside the field they were focused on: browser tabs, the window title, the clock, a notification banner, an autocomplete dropdown, a name in the sidebar, a reflection. Zoom out and read the whole frame before you export.

Does the redacted file keep any metadata?

No. The export is encoded from a canvas, so the resulting file carries no EXIF from the original.
