CSS Filter Generator

Blur, brightness, contrast, saturation, grayscale, sepia, hue-rotate, invert, opacity and drop-shadow, combined into a single filter (or backdrop-filter) value -- plus a real-image preview, presets, randomize, and export to CSS, Tailwind, SCSS or React.

What this tool does

Combines every CSS filter function into a single clean filter (or backdrop-filter) value, with a preview that can use your own uploaded image instead of a generic placeholder — since a filter's effect looks very different on a photo than on a flat gradient block.

Filter functions

Blur, brightness, contrast, saturation, grayscale, sepia, hue-rotate, invert, and opacity each have their own slider, plus a separate drop-shadow with its own X/Y offset, blur, and colour. Only functions actually changed from their default are included in the generated value.

filter vs backdrop-filter

A toggle switches the same combined value from filter (which affects the element itself) to backdrop-filter (which affects whatever is visible behind a translucent element) — the same controls building either one, including the -webkit- prefix backdrop-filter still needs in some browsers.

Previewing on a real image

Upload any image to see exactly how the combined filter looks on real content, rather than judging it against a flat colour block that hides how blur, contrast, or hue-rotate actually reads on a photo.

Presets and randomizing

Nine presets cover common looks — Vintage, Black & White, Cold, Warm, Vivid, Dreamy Soft, Noir, X-Ray Invert, and Frosted Glass (which uses backdrop-filter) — plus a randomize button for quick exploration.

Getting the CSS out

Export as plain CSS, a Tailwind arbitrary-value class, SCSS, or a React inline style object, copyable with one click.

Privacy

Everything, including any uploaded image, is processed entirely in your browser -- nothing is sent to a server.

FAQ

Frequently asked questions

Is my uploaded image sent anywhere?
No. The image and every filter calculation stay entirely in the browser -- nothing is uploaded to a server.
Can I preview the filter on my own photo instead of a placeholder?
Yes -- uploading an image shows exactly how the combined filter looks on real content, which reads very differently than on a flat colour block.
What's the difference between applying it as filter versus backdrop-filter?
filter changes the element itself. backdrop-filter changes whatever is visible behind a translucent element instead, which is what a frosted-glass effect needs -- a toggle switches the same set of controls between the two.
Does the drop-shadow function work differently from box-shadow?
Yes -- filter's drop-shadow follows the actual alpha shape of the element (including a transparent PNG's outline), where box-shadow only follows the element's rectangular or rounded box.
What presets are available?
Vintage, Black & White, Cold, Warm, Vivid, Dreamy Soft, Noir, X-Ray Invert, and Frosted Glass (which uses backdrop-filter instead of filter) -- each sets multiple filter functions together for a specific finished look.
What export formats are available?
Plain CSS, a Tailwind arbitrary-value class, SCSS, or a React inline style object -- selectable from a dropdown next to the code output.
