Frequently Asked Questions
How do I blur an image online?
Upload your image, then adjust the blur radius slider to control the intensity. You can blur the entire image or select a specific region by clicking and dragging on the image. Download the result when satisfied.
Can I blur just part of an image?
Yes. Toggle the "Blur Region" mode and click and drag on the image to select a rectangular area. Only that area will be blurred while the rest stays sharp.
What blur radius should I use?
A radius of 5-10 pixels creates a subtle soft focus. For privacy blurring (faces, text), use 15-30 pixels. Higher values create a stronger blur effect.
Is my data safe?
Yes! All processing happens entirely in your browser using the HTML5 Canvas API. Your images are never uploaded to any server. No data is collected, stored, or transmitted.
Does blurring reduce image quality?
The blur effect is applied non-destructively to a copy of your image. The output is exported as PNG, preserving maximum quality. Your original file is never modified.
