How to make a CSS filter online

  1. Start from a preset or a slider

    Pick a preset like Grayscale or Vintage to get moving, or go straight to the sliders for full control.

  2. Tune the nine effects

    Adjust blur, brightness, contrast, grayscale, hue rotate, invert, opacity, saturate, and sepia while the sample block updates with every move.

  3. Read the CSS

    The filter declaration below the sliders lists only the effects you changed, so it stays short and paste-ready.

  4. Copy the code

    Click Copy CSS to grab the complete filter declaration and drop it onto any element in your stylesheet.

Why use this tool

All nine filter functions

Blur, brightness, contrast, grayscale, hue rotate, invert, opacity, saturate, and sepia, each on its own slider with a live numeric readout.

Live preview on a colorful sample

Every change restyles a bright sample block instantly, so you judge the effect by eye across a full range of colors instead of guessing at numbers.

Clean, minimal output

The generated declaration includes only the functions you moved off their neutral value, so you never copy a wall of redundant defaults.

Presets and one-click reset

Start from looks like Vivid, Sepia, Cool, or Invert, then fine-tune, and reset everything back to neutral whenever you want a clean slate.

Paste-ready declaration

The output is a complete filter rule ending in a semicolon, not a bare value you still have to wrap yourself.

Runs entirely in your browser

Everything happens on your device; nothing is uploaded, stored, or logged.

About this tool

This CSS filter generator builds a filter declaration from nine controls: blur, brightness, contrast, grayscale, hue rotate, invert, opacity, saturate, and sepia. Each slider restyles a colorful sample block the moment you move it, so the effect you copy is exactly the one you were looking at. The order of the functions is preserved, which matters because filters compose in sequence and swapping their order can change the result.

The output stays deliberately short. Only the functions you nudge off their neutral value appear in the CSS, so a simple grayscale look copies as a single function rather than all nine. Presets like Vivid, Sepia, Vintage, Cool, Warm, and Invert give you a strong starting point, and a reset button returns every slider to neutral. Ranges cover the values interfaces actually use: blur up to 20 pixels, brightness and contrast and saturate up to 200 percent, and a full 360 degrees of hue rotation.

The filter you build applies to any element, whether that is a photo, a background, an icon, or a card. It renders live in your browser with nothing to sign up for. Pair it with the CSS gradient generator for the surface behind a filtered element, the box shadow generator for depth, or the color converter when a value starts out as HSL or RGB.

Frequently asked questions

What does the CSS filter property do?
The filter property applies graphical effects like blur, color shifts, and brightness changes to an element and everything inside it. You can combine several functions in one declaration, and they are applied in the order they are written.
Which effects can I adjust?
Blur, brightness, contrast, grayscale, hue rotate, invert, opacity, saturate, and sepia. Each has its own slider with sensible ranges, and the sample block updates live so you can compare looks quickly.
Why does the output only list some functions?
Functions left at their neutral value have no visual effect, so they are left out to keep the declaration short. If every slider sits at neutral, the output is filter: none.
How do I use the generated CSS?
Copy the CSS and paste the filter declaration into your stylesheet on the element you want to affect. The output is a complete declaration, so it drops straight into any rule.
Is anything uploaded to a server?
No. The preview is rendered and the CSS is built locally in your browser. Nothing is sent anywhere, stored, or logged.
