Convert HSL color values to LAB for color management with alpha channel support

Design

Convert a Figma px value into iOS pt, Android dp/sp, web rem/vw with a fluid clamp() snippet, a density-bucket render table and a touch-target accessibility audit, as a developer spec card.

Design

Inspect TTF/OTF/WOFF/WOFF2 fonts: metadata, glyph counts, metrics, style flags, Unicode coverage heatmap, glyph SVG previews, ligatures, OpenType features and variable-font axes.

Design

Preview a heading and body font pairing with real copy, sizes, weights, line heights, character samples, and CSS stacks.

Design

Paste a Figma / Tokens Studio variables JSON and export to Tailwind, shadcn CSS variables, Style Dictionary, or SCSS. Preserves color, spacing and font tokens with type inference.

Design

Calculate camera field of view from focal length and sensor size, with scene coverage at distance.

Design

Extract design tokens — colors, numbers, font sizes and strings — from an ECharts theme JSON and export them straight into your design system. Paste a theme object (the kind registered via echarts.init(dom, themeName)) and the tool walks every leaf, tagging each color (with optional named/rgb → hex normalization), spacing number, font size and string, then emits clean CSS variables, a Tailwind theme.extend config, Style Dictionary tokens.json, or SCSS variables. Bridges the gap between an ECharts visualization theme and Figma/CSS/Tailwind design tokens without copying each value by hand.

Design

Generate a clean, copy-paste HTML email signature that renders correctly in Gmail, Outlook, and Apple Mail — with avatar/logo, social icons (auto-detected from your links), accent color, light/dark/auto theme, and a table-based email-safe layout using inline styles. Copy the raw HTML and paste straight into your mail client.
