Ten Standard Functions, Free to Use
CSS filters are part of the open web standard — ten functions anyone can use without licensing or a paid tool. Adjusting sliders visually and copying the resulting code is genuinely all this needs to cost.
What You Get for Free
- No account needed: adjust the filters, copy the CSS — nothing to register first.
- Live visual preview: see the effect on your own image, not just abstract numbers.
- All ten filter functions: blur, brightness, contrast, grayscale, hue-rotate, invert, opacity, saturate, sepia, and drop-shadow.
- No usage limits on how many times you adjust or export.
Who This Is For
Developers wanting a specific visual effect — a grayscale hover state, a vintage-looking photo treatment, a subtle brightness adjustment — without hand-tuning filter values through trial and error. If you need destructive, pixel-level photo editing (actually altering the image file itself), that's a different category of tool entirely — CSS filters are purely a display-time visual effect. For styling how an image or element looks on the page, this is exactly the right amount of tool.
