Frequently Asked Questions
What blur radius should I use? +
For subtle softening, try 1-3 pixels. For a noticeable blur effect, 5-10 pixels works well. For heavy blurring to obscure details, use 15 or higher.
Can I blur just part of the image? +
This tool applies blur to the entire image. For selective blurring (like blurring a face or background), you would need a more advanced image editor with selection tools.
What type of blur algorithm is used? +
The tool uses a CSS-based gaussian blur filter applied through the Canvas API. This is the same high-quality blur used in web browsers and produces smooth, natural-looking results.
Does blurring reduce the image file size? +
When saved as JPG, blurred images often have smaller file sizes because the blur removes high-frequency detail that is harder to compress. PNG file sizes may not change significantly.
