Are uploaded images saved to the server?

No, the upload function is only used for displaying within your browser (local environment) and image data is never sent to any external server. It operates completely safely and essentially offline.

What is the difference between filter and backdrop-filter?

The `filter` property applies effects directly to an element (like an image tag). In contrast, `backdrop-filter` applies effects to the content 'behind' the element. For UIs where you blur the background and place text in front, `backdrop-filter` is used.

Why doesn't the effect change when I reorder filters?

Certain combinations, like 'Contrast' and 'Brightness', may show very little visual difference depending on their order. However, combinations like 'Blur' followed by 'Contrast' will produce clear differences, such as sharper edges.

Saving the generated image fails.

If you loaded an image from an external URL, the browser's CORS (Cross-Origin Resource Sharing) policy may block exporting to Canvas. Please try uploading an image file directly from your device via 'Change Image' and try again.

About CSS Filter & Blend Generator

CSS Filter & Blend Generator is a free developer tool that lets you visually combine powerful CSS image processing properties: filter, backdrop-filter, and mix-blend-mode, and automatically generates the code. It simulates versatile effects like those in photo editing apps right in your browser, ready to be dropped into your website.

You can recreate brightness and contrast adjustments, blurs, sepia tones, and even layer blending like multiply or screen found in Photoshop, all purely with CSS. You can freely change the order of filters via drag-and-drop while previewing the result in real-time. As a new feature, it also supports generating Tailwind CSS classes. The final processed view can even be downloaded as a PNG image.

How to use this tool

STEP 1

Set up the preview image

Use the "Change Image" button to load an image from your computer or smartphone for preview. The image is never uploaded to a server, keeping it safe. You can also adjust the canvas aspect ratio and background pattern.

STEP 2

Add and reorder filters

Select options like Blur or Contrast and click "Add". You can adjust the intensity of added filters using sliders, and reorder them by dragging the handle on the left.

STEP 3

Copy code and save image

The configured filter effects are instantly output as CSS and Tailwind CSS code. Paste it into your site's stylesheet. By clicking "Save Image", advanced Canvas rendering technology allows you to save the exact preview as a high-quality image.

glossary,

CSS Filter Glossary

filter: A CSS property that applies visual effects directly to an element (usually an image). Functions like blur, brightness, and color changes can be specified separated by spaces, and they are processed from left to right in the order specified.
backdrop-filter: Applies filter effects to the area "behind" the element. The element itself must be semi-transparent. This is essential for modern "Glassmorphism" effects that blur the background image.
mix-blend-mode: Specifies how an element blends with the content behind it. Similar to layer blending modes in Photoshop, you can choose from multiply, screen, overlay, etc., enabling complex color expressions.
Tailwind CSS: A utility-first CSS framework. This tool can output complex filter combinations as concise class names like backdrop-blur-md or mix-blend-multiply.

Use Cases

🔍

Building Glassmorphism UI

By making the background color of a modal window or sticky header semi-transparent and blurring it with backdrop-filter, you can easily implement modern depth expressions and card UIs similar to iOS or macOS.

🌅

Adjusting Hero Header Backgrounds

When placing text over a hero image, lowering the brightness and slightly blurring the background image can balance text visibility and aesthetic appeal.

🖱️

Dynamic Hover Interactions

Perfect for dynamic effects, such as keeping an image grayscale normally, and returning it to color with a shadow on mouse hover.

🎨

Dark Mode Image Adjustments

When a user's OS is set to dark mode, you can use media queries to slightly darken or apply a sepia tone to images to reduce glare.

Technical Details

Importance of Filter Order

The biggest technical point in CSS filters is the "order". For example, filter: saturate(200%) blur(5px); and filter: blur(5px) saturate(200%); render slightly differently. The former enhances color then blurs, while the latter blurs then enhances the blurred colors.

Our tool lets you see these differences in real-time via drag-and-drop.

Hardware Acceleration and Canvas Export

These filter effects use device GPU (hardware acceleration) for fast rendering, which performs better than saving a processed image and loading it dynamically.

Furthermore, the "Save Image" feature utilizes the Canvas 2D API's globalCompositeOperation to simulate the browser's CSS rendering pixel-by-pixel, outputting it as a single high-quality PNG.
