A free collection of everyday converters, calculators, text utilities, image tools, color tools, and developer helpers.

Landing page captured for the 2026-09-09 issue.

Field notes

The homepage organizes 75 utilities into searchable categories rather than presenting a single-purpose calculator. Its examples range from live-updating word counts and epoch conversion to image processing, WCAG contrast ratios, JWT inspection, Markdown rendering, and CSS box-shadow construction. The page states that the tools run entirely in the browser and that inputs are not uploaded; those are presented as site claims rather than independently verified behavior. Currency conversion is described as using live ECB rates.
