Free Online Utility Tools

Some problems do not fit neatly into a category: you need a strong password right now, a JSON blob formatted for readability, a Unix timestamp turned into a readable date, or a quick check of whether two colors pass WCAG contrast rules. MiToolHub’s utilities section collects these everyday helpers in one place, each on its own focused page.

The set includes a secure password generator with adjustable length and character sets, a JSON formatter and validator, a timestamp converter with live date previews, a WCAG color-contrast checker with a color-blind preview, and a cron expression builder that shows the next scheduled runs.

As with every tool on the site, these utilities run entirely in your browser. Passwords are generated locally and never transmitted, your data stays private, and there is nothing to install - just open a page, get the answer, and move on.
