What is this “General Utility” toolbox?

This page groups together a set of small, fast utilities that people use all the time: text counters, random generators, simple validators, and time helpers. Instead of opening multiple tabs or apps, you can keep this page pinned and reach for the tool you need in a couple of clicks.

1. Text tools

The text tools are designed for writers, students, developers, and anyone who works with content. They run entirely in your browser – your text is not sent to a server.

  • Text counter – counts characters, characters without spaces, words, and lines in real time.
  • Case converter – quickly switch between UPPERCASE, lowercase, Title Case, and Sentence case.
  • Text clean‑up – trim leading/trailing spaces, collapse multiple spaces, and remove blank lines.

2. Random generators & dice

These tools use JavaScript’s built‑in pseudo‑random generator. They are fine for everyday use, games, and simulations, but not for cryptographic security.

  • Random number generator – choose a range and how many numbers you need, with an option to avoid duplicates.
  • Dice roller – roll standard dice (d4, d6, d8, d10, d12, d20) or any custom number of sides, with a modifier.
  • Password generator – create strong passwords with configurable length and character sets.

3. Validators

Validators on this page check only the format of the input, not whether an email or URL actually exists or is reachable.

  • Email format validator – checks that an address matches common email syntax rules.
  • URL validator – verifies that a URL is well‑formed and uses an allowed scheme (http, https, ftp).
  • Luhn checksum – tests if a numeric string passes the Luhn algorithm, used in many ID and card numbers.

4. Time helpers

Time helpers are ideal for quick work‑log calculations, simple timers, and converting durations between formats.

  • Time difference – duration between two times on the same day, in hours and minutes.
  • Seconds ⇄ H:M:S – convert seconds to hours:minutes:seconds and back.

Tips for using this page efficiently

  • Use the tabs at the top to jump directly to the type of tool you need.
  • Most inputs update instantly; you can experiment freely without losing data.
  • Because everything runs in your browser, you can safely use it offline after the page loads.
