CSS filter generator
This tool builds a ready-to-paste CSS filter (or backdrop-filter) declaration from a set of visual controls, so you don't have to remember the syntax for combining blur, brightness, contrast, grayscale, hue-rotate, invert, opacity, saturate, sepia and drop-shadow into one property. It's aimed at anyone styling a photo gallery, a hover effect, a frosted-glass panel or a themed image treatment without writing the filter function list by hand.
Each function has its own field, and the generated value only lists the ones you've actually changed — so a page with just a small blur stays short instead of listing nine no-op functions. The function order field controls the order they run in, since CSS filters apply left to right and reordering them (blurring before or after adjusting contrast, for instance) can change the visual result. Two presets, vintage and black & white, set a whole group of values at once for a common look. Toggle "backdrop-filter" to filter what's behind an element instead of the element itself — the standard choice for glassmorphism panels — and switch the output format to get a Tailwind arbitrary-value class instead of a plain CSS line.
Numeric fields are clamped to sane ranges automatically, so an accidental huge or negative value never breaks the output; the drop shadow color field accepts any CSS color value. The result updates live as you adjust any option, and the tally above the output counts how many functions are actually active.
Everything runs locally in your browser — nothing you enter here is uploaded or sent anywhere. Copy the result, download it as a .txt file, or send it to the input of another tool to keep working on it.
FAQ
What is the difference between filter and backdrop-filter?
`filter` applies to the element itself and everything drawn inside it; `backdrop-filter` applies to whatever is visible behind the element, which is what creates a frosted-glass effect over a background.
Why does the order of the filter functions matter?
CSS applies filter functions left to right, each one operating on the result of the previous one. Blurring before adjusting contrast can look different from adjusting contrast first, so reordering them can change the final look even with the same values.
What do the vintage and black & white presets change?
Vintage sets a warm mix of sepia, saturation, contrast, brightness and a slight hue shift; black & white sets grayscale to 100% with a small contrast boost. Either preset overrides the individual sliders while it is selected.
Can I use the generated CSS with Tailwind?
Yes. Switch the output format to "Tailwind class" and the tool wraps the same declaration in Tailwind's arbitrary-property syntax, e.g. `[filter:blur(4px)_grayscale(50%)]`, so you can drop it straight into a `class` attribute.
Is my input uploaded anywhere?
No. The filter is generated entirely in your browser from the options you set — nothing is sent to a server.
