What this tool does
The CSS filter property applies graphical effects like blur and color adjustment directly in the browser, without editing the source image. Combining several functions in one declaration is fiddly to write by hand — this tool builds the string for you as you adjust each effect, and only includes the functions you've actually changed.
How to use it
- Drag the sliders to adjust each filter function.
- Watch the preview box update live.
- Copy the generated filter declaration into your stylesheet.
Privacy
This tool runs entirely in your browser. Your input is never uploaded, stored or shared — closing the tab removes it.
Frequently asked questions
- Can I apply this to a background image instead of an element?
- Yes — filter works on any element, including ones with a background-image. For blurring only the background behind an element (not its content), use backdrop-filter instead.
- Does filter affect performance?
- Complex or animated filters, especially blur, can be expensive to render at large sizes. Test on the actual devices you're targeting before shipping an animated filter.
- Why does the order of filter functions matter?
- Each function is applied to the output of the previous one, so grayscale(100%) sepia(50%) can look different from the reverse order. This tool applies them in a fixed, common-sense order.
