Frequently asked questions
Is this a Gaussian blur?
Yes — it uses the browser's native Gaussian blur filter for a smooth, high-quality result at any strength.
Can I blur just part of the image?
This tool blurs the whole image. To blur only faces or specific regions, use our Blur Face tool instead.
Can I blur many images at once?
Yes. Add as many as you like — a single image downloads directly and multiple images download together as a ZIP.
Is it free and private?
Yes. No sign-up and no watermark, and every image is processed locally in your browser.
