Frequently Asked Questions

How does the blur effect work?

The tool applies a Gaussian blur filter using the browser Canvas API. Adjust the radius slider to control blur intensity from subtle (1px) to heavy (50px).

What image formats are supported?

JPG, PNG, and WebP. Output keeps the same format as the input.

Is my image uploaded?

No. Blur processing runs entirely in your browser. Your image never leaves your device.

Can I blur part of an image?

This tool blurs the entire image. For selective blur, crop the area first with the Image Cropper, blur it, then composite — or use a dedicated photo editor.

Does blurring reduce file size?

Blurring can slightly reduce JPEG file size because smooth areas compress better, but the main purpose is visual effect, not compression.

What type of blur is applied?

Gaussian blur, which produces a smooth, natural-looking softening effect.

Can I blur only part of an image?

This tool blurs the entire image. Crop a region first with the Image Cropper for selective blur.
