Redact Image Online — Free, No Upload Required
Blacking out a name, account number, or face in a screenshot before sharing it seems simple, but doing it wrong is a well-known failure mode — a “blur” that can be reversed, or a black box that’s actually just a semi-transparent layer sitting on top of readable text. This tool draws permanent, irreversible redaction boxes directly into the pixel data, so what’s covered is genuinely gone from the exported file.
Why local processing matters here: redaction exists specifically because an image contains something you don’t want seen — which makes it one of the worst possible categories of file to hand to a server you don’t control before the sensitive part has even been removed yet.
How to use it
- Upload the image.
- Draw boxes over each area you want hidden — names, numbers, faces, signatures.
- Choose a redaction style: solid black, solid color, or pixelation.
- Zoom in to double-check edges of each box fully cover the content.
- Export — the redacted areas are flattened permanently into the image.
Common situations this solves
- Hiding an account number or order ID before posting a screenshot for support
- Blacking out a name or address on a document photo shared publicly
- Covering a face in a group photo before sharing more broadly
- Redacting a signature from a scanned contract before sending a partial copy
- Removing a visible price or internal note from a screenshot
FAQ
Is this actually permanent, unlike a blur?
Yes — the tool flattens the redaction into the pixel data on export, unlike a blur or overlay in some editors that can sometimes be reversed or seen through at full resolution.
Should I use solid black or pixelation?
Solid black is safest for text and numbers since there’s zero chance of any underlying detail bleeding through; pixelation is sometimes preferred for faces where you want to show “a redaction happened here” more visibly, but solid black is more reliably unrecoverable.
Can I redact multiple areas in one pass?
Yes, draw as many boxes as you need before exporting once.
Will this also remove hidden metadata, like GPS location?
No — redaction only affects visible pixels. For metadata like camera info or location tags, run the file through Bare — metadata stripper as well.
Can I undo a redaction box if I misplace it?
Yes, before exporting you can remove or resize any box freely.
