CSS Filter Generator

The CSS Filter Generator lets you build and combine CSS filter effects visually, with a live image preview so you never have to guess at values. Adjust blur, brightness, contrast, color, and more, then copy the exact filter property straight into your stylesheet.

It is made for front-end developers and designers who want to dial in image and hover effects without the edit-save-refresh loop. Every standard filter function has its own slider and number input, and ten ready-made presets give you a polished look to start from.

Private by design: the preview and any image you upload are processed entirely in your browser. Nothing is ever uploaded to a server, so your images stay on your device.

How to Use the CSS Filter Generator

Adjust the filters

Drag any slider to change a filter, or type an exact figure into its number input. The image preview and the generated CSS both update in real time as you go.

Start from a preset (optional)

Click a preset thumbnail — such as Vintage, Noir, or Dramatic — to apply a ready-made look, then fine-tune the individual filters from there.

Toggle and compare

Use each filter's checkbox to switch it on or off without losing its value, and hold the eye button to peek at the original, unfiltered image.

Copy the CSS

The complete filter property appears below the preview. Click Copy to send it to your clipboard, ready to paste into your stylesheet.

Frequently Asked Questions

What CSS filters does this generator support?

It covers nine standard CSS filter functions: blur(), brightness(), contrast(), grayscale(), hue-rotate(), invert(), opacity(), saturate(), and sepia().

How do I combine multiple CSS filters?

Adjust as many filters as you like at once. The CSS filter property supports chaining functions, and the tool automatically writes them out in a single combined filter declaration.

How do I blur an image in CSS?

Increase the Blur slider, which maps to filter: blur() in pixels (up to 20px here). Watch the preview, then copy the generated property — for example filter: blur(4px);.

How do I make an image grayscale in CSS?

Set the Grayscale slider to 100%, which produces filter: grayscale(100%); for a full black-and-white image. Any value in between gives a partial desaturation. The Noir preset combines this with a contrast boost.

What do the presets do?

Presets are predefined filter combinations that create popular looks. Vintage, for instance, mixes sepia with adjusted brightness, contrast, and saturation. Apply one as a starting point, then tweak individual filters to taste.

Is my uploaded image sent to a server?

No. When you upload an image it is read locally with your browser's FileReader and shown only in the preview. The image never leaves your device and is not uploaded anywhere.
