About this tool
Fastols' Blur Image tool lets you blur any part of an image, or the whole thing, by an amount you control — no photo editing software required. Upload your image, drag the slider, and see the live preview before downloading.
It's handy for hiding a phone number, a face, or any sensitive detail in a photo, or even for creating a blurred background for a design or post. Everything runs fully inside your browser, and your images are never uploaded anywhere.
