In web design and UI layout, a cluttered background often affects text readability and visual hierarchy. Based on Gaussian blur and semi-transparent mask overlay algorithms, this tool quickly processes uploaded original images into high-fidelity frosted glass effects. It outputs blurred background images that can be directly used for front-end development or poster design.
We recommend uploading clear original images with a resolution of at least 1080p. Resolutions that are too low may result in noticeable noise after blurring. When processing oversized files (e.g., over 4000px), you may encounter browser memory limits, so it is advisable to compress them appropriately first. The generated results are for visual reference only. Actual rendering of the CSS backdrop-filter property varies across different browsers, so please refer to your actual deployment environment.
In front-end development, the frosted glass effect is typically implemented using the CSS backdrop-filter: blur() property, but this property has limited compatibility with complex backgrounds. Using this tool to generate static frosted glass background images as a fallback solution or fixed background layer can significantly improve rendering performance on low-end devices. We recommend exporting in PNG format to preserve the semi-transparent channel, making it easier to achieve a more natural blending effect when overlaying text and UI components in Figma, Sketch, or code.
