Frontend Developer Toolkit

Generate CSS, tune colors, check contrast, and optimize images — instantly.

Frontend work lives at the intersection of code and design: a gradient here, a box-shadow there, a color converted from a designer's HEX, an image squeezed down before it ships. This workspace gathers the CSS, color, and image utilities you reach for while building interfaces.

Image tools run locally too, so assets are optimized on your device rather than uploaded to a stranger's server.

The workflow

  1. 1

    Convert the color

    Translate a designer's HEX into RGB or HSL for your stylesheet, or sample a color directly.

  2. 2

    Generate the CSS

    Build gradients, box-shadows, and fluid clamp() values without memorizing the syntax.

  3. 3

    Check accessibility

    Verify text/background contrast meets WCAG before it reaches users.

  4. 4

    Optimize images

    Compress and resize images locally so pages stay fast and CLS stays low.
