Handy utilities for day-to-day tasks — generate strong passwords, create QR codes, calculate percentages, count words and characters, estimate your BMI, and count down to any date or deadline. All tools run instantly in your browser without any sign-up or installation.

Nine tools for the small jobs that come up between the big ones. The PDF toolkit merges, splits, watermarks, rotates, and re-orders pages without ever uploading the file. The color-contrast checker grades against WCAG 2.1 AA and AAA with a live preview pane. The readability analyzer runs Flesch, Flesch-Kincaid, Gunning Fog, SMOG, Coleman-Liau and ARI side by side. The password generator pulls bytes from the same Web Crypto source browsers use for TLS — never Math.random(). Each tool is small, focused, and complete; pick what you need and move on.
