Hide private details with solid black blocks, then download a new PNG. Your screenshot stays in this browser and is never uploaded by this tool.
Selected pixels are replaced in the exported file. You must find and cover every sensitive detail yourself. Leave a margin around text and inspect the entire result before sharing. Transparent areas become white; colours may change during browser decoding.
Choose a screenshot
Choose or drop one image. Maximum 24 MiB, 16 million pixels, and 16,384 pixels on either side. Animated images, GIF, SVG, HEIC and AVIF are not supported.
Preparing local image controls.
Redact sensitive details
Drag with a mouse or one finger to add a black rectangle. Regions use original image pixels, even when this preview is smaller. Use the numeric controls below for precise or keyboard editing. Rotate or resize the window after finishing a drag.
Undo retains the last 50 region actions while this page is open. Reset removes the screenshot and all regions. No image or region history is saved to browser storage.
At least one registered area is required. Save or cancel coordinate edits before exporting. Changes remove the previous download until a new PNG is prepared.
Review the exported result
The preview below comes from the same PNG offered for download. All selected regions passed a full opacity and black-pixel check. Unselected pixels were checked against the browser's flattened source image.
Inspect every part of the saved image before sharing, especially small text and anything near rectangle edges. The tool cannot identify information you missed.
