The CSS Filter Generator lets you build the CSS filter property visually. Drag sliders for blur, brightness, contrast, grayscale, hue-rotate, invert, opacity, saturate, and sepia, watch the effect update live on a sample image (or upload your own), and copy ready-to-use CSS — no need to remember each function or its units.
Start from a preset like grayscale, sepia, vintage, or vivid and fine-tune from there, then copy the result as plain CSS or a Tailwind arbitrary-value class. Everything runs in your browser and no image you preview is uploaded anywhere.
How to use the CSS filter generator
- Pick a preset to get started, or drag the sliders for the effects you want.
- Optionally click “Preview on your image” to see the filter on your own photo instead of the sample.
- Only the functions you change are included in the output, so the CSS stays clean.
- Copy the generated CSS (or Tailwind class) and paste it into your stylesheet.
What the filter functions do
The CSS filter property applies graphical effects in order, left to right. blur() softens the element; brightness() and contrast() adjust light and tonal range; grayscale() and sepia() drain or warm the colour; hue-rotate() spins every colour around the wheel; invert() flips colours to their opposite; saturate() intensifies or mutes colour; and opacity() controls transparency. Percentages use 100% as the untouched baseline, so brightness(150%) is brighter and saturate(50%) is more muted.
Combining filters
You can chain several functions in a single filter declaration separated by spaces, and this tool does that for you. Order matters: blur applied before or after a colour change can look different, and the browser evaluates them in the order written. Because filters are hardware-accelerated, they are a cheap way to restyle images and UI without editing the source file — great for hover states, disabled looks (grayscale), and image treatments.
Filters vs. editing the image
CSS filters are non-destructive and applied at render time, so the same image can look different across themes or states without exporting new files. They also apply to any element — text, icons, backgrounds, and whole sections — not just images. For a frosted-glass panel look, pair backdrop effects with the Glassmorphism generator; for drop shadows on shapes, the Box Shadow generator is a better fit than the drop-shadow() filter for most layouts.
Frequently Asked Questions
What does the CSS filter property do?
It applies visual effects — blur, brightness, contrast, grayscale, hue-rotate, invert, opacity, saturate, and sepia — to an element at render time, without changing the underlying image or content.
Can I combine multiple filters?
Yes. List several functions separated by spaces, e.g. filter: contrast(120%) saturate(150%) blur(1px). They apply in order, and this generator builds the combined value for you.
Why is my filter output sometimes “none”?
When every slider is at its default (100% for brightness, contrast, saturate and opacity; 0 for the rest), there is no effect to apply, so the value is none. Change any slider and the relevant function appears.
Is my uploaded image sent anywhere?
No. The preview image is read and rendered entirely in your browser using an object URL. Nothing is uploaded to a server.
Can I get the filter as a Tailwind class?
Yes. Switch the output to “Tailwind” to get an arbitrary [filter:…] class (or filter-none at defaults). Underscores stand in for spaces in Tailwind arbitrary values.
Do CSS filters work in all browsers?
Yes. The filter property is supported in all modern browsers, so the generated CSS works everywhere without vendor prefixes.
