CSS Filter Generator

How to use

1. 1Pick a quick preset (Vintage, Black and white, Cool, Warm, Soft glow, Sharpen, Dim, Invert, or Frosted) to load a working filter stack, or start from scratch with all functions disabled.
2. 2Toggle a filter function with its checkbox, then drag the slider to set the value. Identity values (like brightness 100%) are flagged so you can tell when a filter is on but invisible.
3. 3For drop-shadow, set X and Y offsets, blur radius, color, and opacity. Drop-shadow respects the alpha edges of the element, unlike box-shadow.
4. 4Switch the preview subject (Image, Text, Card) and background (Light, Dark, Checker) to see how the filter reads on the surface where it will ship.
5. 5Click Copy CSS to grab the filter shorthand, or Copy class for the Tailwind v3+ arbitrary-value utility. Disable all clears the stack without resetting individual values.

About this tool

CSS Filter Generator is a visual playground for the CSS filter property. Toggle each filter function on or off with a checkbox and shape the result with a slider, then watch a live preview render the same filter shorthand the tool will copy. Supports the full set of filter functions: blur (in pixels) for soft Gaussian fades, brightness, contrast, and saturate (in percent, with 100% as the identity), grayscale, sepia, and invert (in percent), hue-rotate (in degrees) for color shifts around the wheel, opacity for transparency that affects the entire filter chain, and drop-shadow with x and y offsets, blur radius, color, and alpha. Drop-shadow follows the actual shape of the element, including the alpha edges of PNGs and SVG paths, which is the key difference from box-shadow that always traces the bounding box. Quick presets cover the most common looks: Vintage warms colors with sepia and saturation, Black and white pulls full grayscale plus a contrast bump, Cool and Warm shift hue toward blue or amber, Soft glow blurs lightly and adds a colored drop-shadow, Sharpen pushes contrast and saturation, Dim lowers brightness for image overlays, Invert flips colors for dark-mode mockups, and Frosted blurs heavily for glass-morphism backdrops. The preview lets you switch the subject (Image, Text, or Card) and the background (Light, Dark, or a checker pattern) so you can verify how the filter reads on the surface where it will ship. The output is a real CSS filter shorthand that respects function order, an automatically generated Tailwind v3+ arbitrary-value class using the filter-[...] syntax with underscores in place of spaces, and a per-layer drop-shadow snippet you can copy on its own. Disabled filters are skipped, so the copied value is exactly what you see and nothing more. Useful for image treatments, hero backgrounds, glass-morphism cards, hover and focus states, dark-mode adjustments, decorative SVG accents, and any place where a small CSS filter chain replaces a heavier image edit. Everything runs locally on your device. The settings, colors, and preview never leave your browser.
