About this tool

Image Pixelator hides sensitive areas of any image so you can share screenshots, photos, and document scans without leaking what is inside them. Drop a PNG, JPG, WebP, BMP, or GIF and the preview opens in your browser; click and drag anywhere on the image to draw a rectangle, and the area inside it is immediately rendered with the effect you chose. Pixelate produces a classic mosaic by downscaling the rectangle and upscaling it back with nearest-neighbour sampling, with a configurable block size up to 80 pixels for stronger privacy. Blur applies a Gaussian-style filter inside a clipped region so the halo never bleeds past the edges of the rectangle, with a configurable radius. Black bar paints a solid opaque rectangle that fully replaces the pixels underneath; this is the strongest redaction because no information about the original content remains in the exported file. You can add as many rectangles as you need (one per face, one per username, one per address, one per private screen), select each one to fine-tune its position and size with the corner and edge handles, and remove any rectangle from the side list. The live preview already renders the same effect that will be exported, so what you see is what you download. When you are happy with the redaction, choose an output format (keep the original, force PNG for lossless redaction of screenshots, JPEG for small photos, or WebP for the smallest file), set the quality for lossy formats, and click Render full resolution to produce the export at the source image's exact dimensions; the result downloads with a .redacted suffix so it does not overwrite the original. Useful for redacting personal information out of screenshots before posting them in a bug report, hiding faces and license plates in photos before sharing them publicly, blurring usernames in customer support tickets, covering home addresses in shipping confirmations, anonymizing whiteboard photos before a write-up, and any other moment when you would otherwise reach for a heavy photo editor just to scrub a few sensitive details. The image you pick, the rectangles you draw, and the redacted result never leave your device: everything runs locally on an HTML canvas in your browser. If you also want to strip EXIF data, GPS coordinates, and other hidden metadata from the file, run the result through Image Metadata Remover.
