Hide My Image — redact, blur, pixelate or black out an image online
Hide My Image is a free online image redaction tool: load a photo or screenshot, drag a box over anything you want to hide, and it is pixelated, blurred or covered with a solid black bar right in your browser. It is the quick way to redact sensitive information — names, addresses, account numbers, faces, signatures — before you share a screenshot, without installing anything or uploading your image to a server.
Pick one of three effects (pixelate, blur or solid), draw a rectangle over the part to censor, and the redaction is burned into the picture so it cannot be undone by the viewer. Made a mistake? Undo it; happy with the result? Download it as a PNG. Everything runs 100% client-side on an in-browser canvas — nothing you load is uploaded, so it is safe for private documents and confidential screenshots; 0 bytes leave your browser.
Usage
- Add an image: click "＋ drop or select an image" to choose a file, or drag and drop an image straight onto the canvas. PNG, JPG, WebP and other browser-supported image formats work.
- Choose an effect with the tool buttons — "pixelate" (mosaic the selection), "blur" (gaussian blur the selection) or "solid" (cover with a black bar).
- Drag a box over the area you want to hide. Releasing the mouse (or lifting your finger on touch) applies the current effect to that rectangle and bakes it into the image.
- Repeat for every region you need to redact — switch effects between selections if you like. Click "↶ undo" to step back one redaction at a time if you over-draw.
- Click "↓ download png" to save the redacted image as a PNG. Use "✕ remove" to clear the current image and start over with a new one.
Examples
- Black out text in a screenshot:
tool: solid · drag over the text - Pick "solid" and drag a box over an email address, password or account number in a screenshot. The selection is filled with an opaque black bar — the classic redaction look — so the underlying text is gone for good, not just hidden behind a layer.
- Blur a face or a logo:
tool: blur · drag over the face - Choose "blur" and drag over a face, a license plate or a brand logo to soften it with a gaussian blur. Useful when you want to obscure something while keeping the overall look of the photo natural rather than masking it with a hard rectangle.
- Pixelate a sensitive region:
tool: pixelate · drag over the region - Select "pixelate" and drag over the area to mosaic it into coarse blocks. This is the familiar "censored" effect for hiding signatures, ID numbers or anything you want unreadable while still showing roughly where it was.
FAQ
- How do I redact an image online for free?
- Load your image, pick an effect (pixelate, blur or solid black bar), and drag a box over each part you want to hide. Then click "↓ download png" to save the redacted image. It is completely free with no sign-up, because the whole thing runs in your browser.
- How do I blur or pixelate part of a picture?
- Choose the "blur" or "pixelate" tool button, then drag a rectangle over the region you want to obscure. Blur applies a gaussian blur to the selection; pixelate turns it into coarse mosaic blocks. You can apply as many selections as you need and undo any that go wrong.
- Can the redaction be reversed or undone by someone else?
- No. Each effect is drawn permanently onto the image pixels and the original data underneath is discarded, so a viewer cannot peel back a black bar or un-blur the region from the downloaded PNG. The "↶ undo" button only steps back your own edits while you are still working — it does not survive in the saved file.
- Is my image uploaded anywhere?
- No. The image is loaded into an in-browser canvas and every redaction — pixelate, blur and solid — is applied locally. Nothing you load is sent to a server, which makes it safe to redact private documents and confidential screenshots; 0 bytes leave your browser.
