CSS Filter Generator

How to use it

1. Drag any of the eight sliders. The preview updates as you move, so you can judge the look before copying anything.
2. Start from a Preset when you want a direction: vintage adds sepia and pulls saturation down, monochrome goes fully gray, cool tone rotates the hue.
3. Re-adjust any slider after applying a preset; the preset only sets starting values.
4. Copy the generated filter declaration. Only functions that differ from their neutral value are written out, so the string stays short.
5. Apply the same string to your own image. The preview uses a gradient placeholder, but the filter math is identical.

Common use cases

• Hover and state effects — dim a thumbnail with brightness and bring it back on hover.
• Toning artwork to match a theme — hue rotate plus saturation shifts a bright image toward a brand palette.
• Placeholder and loading states — blur and grayscale mark an image as not yet loaded.
• Dark mode image handling — a slight brightness and contrast reduction keeps photos from glaring on dark surfaces.
• Teaching what each function does — moving one slider at a time on the same preview shows the isolated effect.

Why it stays private

The filter is applied by your browser to a locally drawn gradient. Your own images are never uploaded because there is no upload step at all.

FAQ

Q: Why does the output skip some functions? A: Functions sitting at their neutral value, such as brightness(100%), change nothing. They are left out so the declaration stays readable.

Q: Can I apply this to a video or a whole section? A: Yes. The filter property works on any element, including video, canvas and containers, though blurring a large area costs more to paint.

Q: Does the order of functions matter? A: It does. Filters apply left to right, so grayscale before sepia gives a different result than the reverse. The generated string keeps a fixed order, so reorder it deliberately if you need to.
