Why doesn't my downloaded PNG have the blur effect?

Image files cannot contain live blur filters. To recreate the glass look in a video editor, place the PNG overlay on your timeline and apply a blur effect to the video layer beneath it.

The Ultimate Guide to the Glass Morphism Generator

The Glass Morphism Generator is a powerful UI design tool that allows you to create stunning frosted-glass effects. Whether you are a web developer looking for the exact CSS backdrop-filter code, or a video editor needing a transparent overlay for Premiere Pro, this tool lets you perfect the look instantly.

Who Will Use This?

Front-End Developers: Stop guessing CSS blur values and RGBA transparencies. Visually build your glass effect and instantly copy the cross-browser compatible CSS code for your next dashboard or landing page.
Video Editors: Export the glass shape as a transparent PNG overlay. Drop it into your Premiere Pro or DaVinci Resolve timeline, add a blur effect to the video underneath, and you instantly have a cinematic, Apple-style frosted glass graphic!
UI/UX Designers: Rapidly prototype different frosted shapes (like a pill-shaped navigation bar or a circular profile picture frame) against various colorful backgrounds to see what looks best.

How to Create the Perfect Frosted Glass Effect

Choose a Template: Start by selecting a Shape Template (e.g., Standard Card, Hero Section, or Pill) to give you a baseline width, height, and corner radius.
Adjust Transparency & Blur: This is the secret to great glassmorphism. Keep the Transparency relatively low (between 10% and 30%) and the Blur Amount high (10px to 25px) so the background colors bleed through smoothly.
Customize the Fill:
- Use a Solid fill (usually white or black) for a standard frosted look.
- Switch to Gradient fill to create a dynamic, shimmering glass effect (perfect for modern Web3 or tech designs).
Refine the Edge: Real glass has a reflective edge. Add a 1px or 2px Border Width, set the Border Color to pure white, and adjust the Border Transparency to around 20%-40% to create a realistic shine.
Test the Background: Click the Change Background button above the preview window to cycle through different vibrant images and gradients to ensure your glass looks great on any surface.
Export: Under the EXPORT section, click COPY CSS to grab the code for your website, or click DOWNLOAD PNG OVERLAY to save the shape as an image file.

Common Problems & Tips

My downloaded PNG doesn't have the blur effect! This is intentional! Image files (like PNGs) cannot contain "live" blur filters that blur the layers beneath them. The PNG export gives you the semi-transparent colored box and border. To recreate the glass look in a video editor, you must place the PNG on your timeline, and then apply a "Gaussian Blur" effect to the video layer directly underneath it.
The glass looks muddy or gray: This usually happens if your background is too dark or lacks contrast, or if your glass transparency is set too high (over 50%). Glassmorphism relies on vibrant, colorful backgrounds to look good.

Frequently Asked Questions

Is the CSS code compatible with all browsers?

Yes! The tool automatically generates both the standard backdrop-filter property and the -webkit-backdrop-filter prefix to ensure the blur effect works properly on Safari and iOS devices.

Why does the tool generate an RGBA color instead of a Hex code?

RGBA (Red, Green, Blue, Alpha) allows us to inject the exact Transparency value you selected on the slider directly into the CSS color code, which is required for the glass effect to work properly.

PRACTICAL EXAMPLES & WORKFLOWS

THE COMPLETE GUIDE: GLASS MORPHISM GENERATOR

How to Use This Tool:
1. Under "GLASS SETTINGS," start by choosing a "Shape Template" (like a Hero Wide section or a Standard Card) to fit your project.
2. Click the "Change Background" button in the Live Preview area to cycle through different vibrant backgrounds. This is crucial for seeing how your glass effect will refract and blur colors behind it!
3. Adjust the "Blur Amount" to change how frosted the glass looks, and tweak the "Transparency" slider to make the glass more or less opaque.
4. Experiment with the "Fill Type." You can use a solid color, or select "Gradient" to create beautiful, shifting light reflections across the surface of your glass.
5. Finally, use the Border controls to add a crisp, semi-transparent edge, which gives the glass its realistic 3D pop.
6. When you are happy with the look, click "COPY CSS" to grab the exact code for your website, or click "DOWNLOAD PNG OVERLAY" to export a transparent image of the glass layer to use in video editing or graphic design.

How This Benefits You:
Writing the exact CSS for cross-browser Glass Morphism (including `backdrop-filter` and webkit fallbacks) involves complex RGBA color math that is tedious to guess by hand. This tool gives you instant visual feedback and generates mathematically perfect, production-ready CSS that you can paste straight into your stylesheet.

Who Should Use This:
