Safeguard your privacy by blurring or redacting secret parts of your images before sharing them. Whether it's a credit card number in a screenshot, a face in a photo, or a private address, FusioFiles Blur Tool lets you hide it instantly. Most online tools upload your secret image to a server to process it. We don't. Our tool runs entirely in your browser. This means you can safely load a screenshot containing PII (Personally Identifiable data), redact it, and download the safe version without the original ever leaving your computer.
