Frequently Asked Questions

Is my data safe?
Yes. All processing happens entirely in your browser. Your data never leaves your device and is never uploaded to any server.
Does glassmorphism work in all browsers?
backdrop-filter is supported in Chrome, Edge, Safari, and Firefox 103+. The generated CSS includes the -webkit- prefix for Safari. Older browsers will show a semi-transparent background without the blur.
What is the saturation slider for?
The saturate() filter increases color vibrancy of the background content visible through the glass. Values above 100% make colors more vivid, enhancing the frosted glass effect.
Why does my glass effect look different on different backgrounds?
Glassmorphism works best on colorful or image backgrounds. On solid white or dark backgrounds, the blur effect is less noticeable since there is less visual content to blur.
