Professional Batch Image Blurring & Anonymization Tool

Gaussian blur is a popular image editing technique that softens the image by averaging the pixels in a specific pattern. It’s named after the Gaussian function used to calculate the blur. This effect creates a smooth, blurred appearance that reduces sharpness and detail, commonly used for background blurring, portrait enhancement, or creating artistic effects.

Our online tool supports batch processing, allowing you to blur multiple images simultaneously. Simply upload several images, and our tool will apply the Gaussian blur effect to all of them in one go, saving you time and effort.

Our tool supports a variety of image formats including JPG,BMP,GIF, PNG, WebP, AVIF, and HEIC. You can upload your photos in these formats and apply the blur effect with ease.

You can easily adjust the intensity of the blur effect using a simple slider. Move the slider to the left for a subtle blur or to the right for a more intense blur. Once you’re happy with the preview, simply click "Start Process" to apply the effect to your images.

Yes, our Image Blur Tool is completely free to use. You don’t need to sign up or provide any personal information. Just upload your images, apply the blur effect, and download the results without any cost.

No. For security and privacy reasons, our tool applies a destructive Gaussian convolution to the pixel data. Once the processed image is generated and downloaded, the original details cannot be recovered by 'unblurring' software, making it safe for hiding sensitive information.

Our engine uses Alpha-Premultiplied Blurring. This prevents the common 'dark halo' effect around the edges of transparent objects, ensuring that the blur blends seamlessly with the alpha channel for professional UI assets.

We support an extensive range of blur radii. From a subtle 1px softening for anti-aliasing to a heavy 100px+ Gaussian wash for abstract backgrounds, our server-side engine maintains consistent performance regardless of intensity.
