Frequently Asked Questions
What type of blur does this tool apply?
This tool applies Gaussian blur via the browser's canvas filter API. It creates a smooth, natural-looking softening effect across the entire image.
Can I blur only part of an image?
Currently, the blur is applied to the entire image. For partial blur (e.g. blurring a face or background), you would need a more advanced editing tool.
What blur radius should I use?
A radius of 5–15 creates a subtle soft effect. 20–35 creates a heavy background blur. 40–50 creates an extreme blur effect for privacy or artistic purposes.
Will the image dimensions change after blurring?
No. The image dimensions stay exactly the same. Only the pixel values are modified by the blur algorithm.
Is my image uploaded to a server?
No. All processing is done locally in your browser using the HTML5 Canvas API. Your image is never sent anywhere.
