PixelVault’s Privacy Blur is the fastest way to hide sensitive information in an image before you share it. Drop in a photo or screenshot, drag a rectangle over anything private — a face, a license plate, a home address, an email, a phone number, an account statement — and it is instantly blurred, pixelated or blacked out. Then download. That is the whole workflow, by design.
Unlike online blur tools that ask you to upload your image first, PixelVault runs entirely in your browser. That distinction matters more here than anywhere else: the image you are redacting is, by definition, the one containing something sensitive. With Privacy Blur the original, unredacted file never leaves your device — there is no server that ever sees the face, the document or the data you are trying to hide.
Three modes cover every situation. Blur softens an area so it reads as background; pixelate replaces it with coarse blocks, the classic look for faces and plates; and redact covers the area in solid black, the safest option for text like account numbers where you want zero chance of recovery. One strength slider controls how heavy the blur and pixelation are — redaction is always total.
How it works
Your image is drawn onto a canvas in your browser. Each rectangle you drag becomes a region, and the selected effect is re-rendered onto the pixels inside it — blur uses a scaled Gaussian filter, pixelate downsamples and re-enlarges the area, and redact fills it with black. Regions stay editable while you work: click to select, drag to move, resize with the handles, press Delete to remove, Ctrl+Z to undo. The download bakes every effect permanently into the exported PNG, JPG or WebP.
Why local processing matters
Uploading an image to a website so it can hide your private information is a contradiction: the service you are trusting to protect the secret is the first thing that sees it. Local processing resolves that completely. The redaction happens on your own hardware, the network is never involved, and the only file that ever leaves your device is the one where the sensitive parts are already unrecoverable.
