About Blur Part of Image
This tool lets you blur or pixelate specific parts of a photo without touching the rest of the image. Upload a picture, then drag a rectangle over anything you want to hide - a face, a license plate, a house number, a name badge, a screenshot with private details - and mark as many areas as you need. Choose a smooth blur or a blocky pixelate (mosaic) effect and adjust the strength, then download the result as a PNG.
Everything runs entirely in your browser using the HTML canvas. Your image is never uploaded to a server and no sign-up is required, so it stays private on your own device. The blur is applied at the image's full resolution, so the download keeps the original dimensions rather than the smaller on-screen preview.
One honest note on privacy: blurring and pixelation obscure detail visually, but a heavy mosaic or a light blur can sometimes be partially reversed by determined tools. For anything you truly need to erase - like a password or account number - use a strong effect over a generous area, or cover it with a solid crop instead.
Frequently asked questions
- How do I blur just one part of a photo?
- Upload your image, then click and drag a rectangle over the area you want to hide. Repeat for as many spots as you like, pick blur or pixelate, set the strength, and click Apply & Download.
- Can I blur more than one area at once?
- Yes. Each rectangle you draw is added to a list of marked areas, and they are all processed together when you download. You can remove any area by clicking it in the list below the image.
- Is my image uploaded anywhere?
- No. All processing happens locally in your browser with the canvas API. The photo never leaves your device and nothing is sent to a server, so it stays completely private.
- What is the difference between blur and pixelate?
- Blur applies a smooth Gaussian-style softening, while pixelate replaces the area with large blocky squares (a mosaic). Pixelate tends to look more deliberate; both are controlled by the strength slider.
- What image formats can I use?
- You can upload common formats like JPG, PNG, WebP, and GIF (first frame). The edited image always downloads as a PNG at the original resolution.
- Will the download be full quality?
- Yes. The on-screen preview is scaled to fit your screen, but the blur is applied to the full-resolution image, so the downloaded PNG keeps the original width and height.
