Networking, scheduling, and design in one place
A grab bag by design: these are the small, single-purpose tools that come up constantly in day-to-day technical work but rarely deserve their own bookmark-worthy site. The subnet calculator handles CIDR math (network/broadcast address, usable host range) for network planning. The timezone converter lines up a chosen time across 60+ world cities with working-hours color coding, useful for scheduling calls across a distributed team. The color converter moves between RGB, HEX, and CMYK for UI and print design work, with a live swatch preview and a screen eyedropper. The SVG to Power Fx converter turns SVG markup into a ready-to-paste formula for a Power Apps Image or HTML Text control.
