Securely Censor & Blur Photos
Our blur image online tool allows you to instantly redact sensitive documents, pixelate license plates, or censor faces securely. By processing everything strictly inside your local browser memory, we guarantee absolute confidentiality. Use the pixelate image online feature for a classic blocky redaction look, or use the soft blur for a professional-grade censorship effect.
Frequently Asked Questions
How to blur a face in a photo?
Upload your photo, select "Soft Blur" from the toolbar, adjust the brush size, and simply paint over the face. The blur will be applied instantly to the areas you touch.
What is pixelate vs blur?
Blur uses a Gaussian-style filter to soften edges and colors, while Pixelate turns the area into small blocks. Both are effective for censoring sensitive info; pixelation is often preferred for a "news" or "undercover" aesthetic.
Is my data private during redaction?
Yes. Redaction is a sensitive task. That's why FormFix does 100% local image processing. Your documents, IDs, or sensitive screenshots never leave your device.
Can I undo a blur stroke?
Currently, you can use the "Clear All" button to start over. We recommend applying the blur accurately in one go or using the clear button if you make a mistake.
