📖 About

CSS Filter & Blend Generator is a free developer tool that allows you to easily combine CSS filter, backdrop-filter, and mix-blend-mode to visually generate photo app-like filters in your browser.

You can replicate image processing like brightness, contrast, blur, and sepia without Photoshop. Drag and drop effects to reorder them and generate the CSS code seamlessly.

🔰 How to Use

1. Set Preview Image
Click "Change Image" to load any picture from your device. Your image is never uploaded to any server. Use the canvas ratio controls and fit settings to frame your image perfectly.
2. Add and Reorder Filters
Select an effect like Blur or Contrast in the "Image Filter" tab and click "Add". Use the sliders to adjust intensity. Drag the [≡] handle to reorder. Order matters in CSS filters!
3. Blend Modes and Backdrops
In the "Backdrop & Blend" tab, change the mix-blend-mode to composite the image with its background. Apply a backdrop-filter to the overlay to create glassmorphism effects.
4. Customize Overlay
Use the "Overlay Settings" tab to adjust the position, size, text, font size, and color of the backdrop overlay element.
5. Copy Code & Save Image
Changes instantly reflect in the Generated CSS area. Click Copy to use the code, or Save Image to download the preview as a PNG file.

📚 Glossary

filter
A CSS property that applies visual effects (blur, brightness, color-shifting, etc.) to an element. Multiple functions can be chained with spaces.
backdrop-filter
Applies filter effects to the area *behind* an element. Often used to create frosted glass or glassmorphism effects.
mix-blend-mode
Determines how an element's content should blend with the content of its background, similar to layer blend modes in Photoshop.

⚙️ Tech Details

The most important part of CSS filters is the Order. For example, filter: saturate(200%) blur(5px); looks different from filter: blur(5px) saturate(200%);. In our tool, you can see this effect instantly by dragging items up and down.
These CSS effects are hardware-accelerated, providing incredible performance for dynamic visual changes compared to serving pre-rendered images.

❓ FAQ

Q. Will my uploaded image be saved to a server?
A. No. The upload function strictly uses your browser's local File Reader to show the preview. We never transmit your data remotely.
Q. Can I use this on my mobile phone?
A. Yes, it fully supports mobile and tablet browsers for generating CSS code anywhere.
Q. What is the difference between filter and backdrop-filter?
A. filter applies effects onto the target element itself. backdrop-filter applies effects to everything behind the element.
Q. Does it work on all web browsers?
A. It is widely supported by modern browsers (Chrome, Edge, Safari, Firefox). A fallback might be required for backdrop-filter on legacy versions.
