Jump straight to the group you need, from everyday text cleanup to developer utilities.
Case family (including Title Case at the shipped /tools/capitalize path), slugify, word and character counts, sort, reverse, line numbers, find/replace, regex, diff, lorem, typing speed, and random pickers. Cleanup stays in the tab.
Format, minify, validate, compare, generate sample JSON, and turn a payload into TypeScript interfaces. These pages share a persist key where noted so you can Convert to a sibling without re-pasting. Invalid JSON is reported, not silently “fixed.”
Base64 and hex, HTML entities, URL encode/decode, color conversion, Markdown preview and HTML export, QR codes, barcodes, and image-as-data-URI. Encoding is not encryption — the pages say so when it matters.
Generate a random password, score a candidate locally, hash or verify bcrypt, and mint UUID v4/v7 or ULID. Strength is a heuristic, not a breach database. Do not test production passwords on a shared machine.
JWT inspect and sign, SQL/XML/HTML/CSS/JS formatters, YAML and CSV conversion, cron builder and explainer, regex tester, hashes, HMAC, timestamps, URL parser, and number bases. Built for pasted snippets, not for connecting to your production database.
Compress JPEG/PNG/WebP, resize with optional aspect lock, convert format, crop with a rectangle, or embed a small file as Base64. Pixels are read in the browser; there is no folder batch upload.
Percent and discount math, units, currency (public mid-market rates), age and working days, GPA, BMI, loan and compound interest, tip and margin, scientific keypad. Formulas and limits are on each article page.
Time zone conversion with IANA names, Unix timestamp parse, stopwatch and laps, countdown, and Pomodoro. Timers are for this tab, not a server crontab — use Cron Builder for five-field schedules.
Visual color picker plus HEX/RGB/HSL conversion, linear gradient, box-shadow, and border CSS you can copy. Pair with CSS Formatter when you want indent. Not a full design-system export.
