Why use this tool
Made for sensitive material
Some text should not be merely softened. Passwords, personal identifiers, account numbers, and confidential labels often need stronger visual certainty than blur provides.
Black box redaction is the clearest way to signal that information was intentionally removed from an image before sharing.
This page is built for that exact use case: cover the text locally in your browser, then download the redacted image.
Questions
Frequently asked questions
What does it mean to black out text in an image?
It means covering the selected text with a solid black box so the original words are no longer visible in the exported image.
Is black box better than blur for text?
For highly sensitive text, yes. Black Box gives the strongest visible redaction because it replaces the selected area entirely instead of softening it.
Can I black out multiple lines or paragraphs?
Yes. Draw as many separate boxes as needed, one for each line, block, or field.
Does this work on screenshots and scanned documents?
Yes. You can black out text in screenshots, document photos, scans, charts, forms, and other images.
Is the image uploaded anywhere?
No. The tool processes the image locally in your browser and never uploads it for editing.
