Why use this tool
Made for sensitive material
Redacting an image means permanently covering the parts that should not be seen. Whether you are sharing a screenshot with a colleague, submitting evidence, or posting a photo publicly, redaction ensures only the intended information is visible.
Black Box mode is identical in visible effect to traditional document redaction. For less visually stark results, Blur and Pixelate provide strong obscuration while looking more natural.
This tool processes your image entirely in your browser. No upload, no storage, and no account required.
Questions
Frequently asked questions
What does "redact" mean?
Redacting means permanently hiding or obscuring information so it cannot be read. In images, this means covering, blurring, or pixelating the sensitive parts.
Is this tool really free?
Yes. No sign-up, no watermark, and no limits on how many images you process.
Can someone reverse the redaction?
If you use Black Box, the pixels are replaced with solid black and this is irreversible. Blur and Pixelate heavily degrade the original content but Black Box is the strongest visual redaction.
Does my image get stored anywhere?
No. The tool runs entirely in your browser. Nothing is sent to a server.
What file formats can I redact?
JPG, PNG, and WebP. The output is always a PNG file.
Can I redact a PDF?
Take a screenshot of the PDF page or export it as an image, then upload that image here.
How many areas can I redact in one image?
There is no limit. Draw as many boxes as you need and each selection adds a new independently redacted region.
Is Black Box redaction the same as traditional document redaction?
Yes. Black Box replaces the selected pixels with solid black and is the same visible effect used in formal document redaction.
Can I redact a photo, not just a document?
Yes. The tool works on photographs, screenshots, scanned documents, and graphics.
