Frequently Asked Questions
Gaussian blur is a digital image processing technique that smooths out a photo by calculating the mathematical average color of surrounding pixels. It mimics looking through a translucent screen or an out-of-focus camera lens, making it perfect for obscuring details or creating soft backgrounds.
Absolutely not. This tool utilizes 100% client-side processing using HTML5 Canvas. Your images are loaded directly into your web browser's local memory and are never sent to or stored on any external servers, ensuring complete privacy for your sensitive files.
No! Unlike many online tools that compress your file to save server costs, our tool runs locally on your machine. When you click Download, it renders the blur onto a full-scale canvas matching your original image's exact pixel dimensions for a lossless export.
Yes. The tool fully supports alpha channels (transparency). Just make sure you select PNG or WebP as your export format before downloading to retain the transparent background. If you export as a JPG, the transparent areas will automatically become solid black or white.
This specific tool applies a uniform, high-quality Gaussian blur across your entire image. It is perfectly designed for creating soft, abstract backgrounds for UI/UX web design, social media quote posts, or completely obscuring full documents.
You can securely upload image files (JPG, PNG, or WebP) up to 20MB in size. Because the processing uses your own device's hardware (GPU/CPU) rather than a remote server, even large, high-resolution files will blur and export remarkably fast.
