Frequently Asked Questions
Why should I use the Blur Image tool?
BrandBird's Blur Image tool lets you selectively blur areas of an image to hide sensitive information, create focus effects, or protect privacy — all in your browser without any server uploads.
How to blur an area of an image online?
1. Upload your image to the Blur tool. 2. Draw a rectangle over the area you want to blur. 3. Adjust the blur intensity and export your image with the sensitive areas hidden.
Are my images safe with this tool?
Yes. All processing happens locally in your browser. Your images are never sent to any external server, ensuring complete privacy.
Can I blur multiple areas in one image?
Yes. Draw multiple blur regions across your image to hide several sensitive areas at the same time before exporting.
What is gaussian blur and how does it work?
Gaussian blur applies a mathematical smoothing function to pixels, blending them with their neighbors. The result is a soft, unfocused effect that makes text and details unreadable while maintaining a natural look.
Is the Blur Image tool free?
Yes, it's completely free. Blur as many images as you need with no sign-up, watermarks, or limits.
How to censor sensitive data in a screenshot for sharing?
Upload the screenshot, select the areas containing sensitive data (emails, passwords, personal info), apply blur, and export. The blurred regions hide the information while the rest of the screenshot remains clear.
What image formats does the blur tool support?
The tool supports PNG, JPEG, and WebP uploads and exports. The output quality matches the original image with only the selected areas blurred.
