About this tool

Combine CSS filters — blur, brightness, contrast, grayscale, sepia, hue-rotate and more — and copy the resulting declaration.

CSS Filter Generator is part of the TmpMailer Image & Media set — free browser utilities that open instantly, need no account, and pair well with a temporary-email workflow when you just need a quick result.

Common use cases

Dimming a hero image behind text.
Creating a hover effect for cards.
Making an image monochrome for a print-style layout.

Common questions

Do filters affect layout?

No. They affect painting only, so a blurred element can visually overflow its box without changing layout.

Are filters expensive?

Blur and large drop shadows are the costly ones. Animating filters can drop frames on low-end phones.

Can I apply a filter to a background image?

Not directly. Apply it to a pseudo-element or wrapper that holds the image.
