Quick tools for real tasks

Format, convert, check, and clean up data in one place

Toolcore is a simple catalog of online tools for developers, technical teams, and everyday desk work. Use it to format JSON, encode text, convert images, make QR codes, check colors, test regex, read timestamps, hash data, count words, and handle other small jobs without setting up a project. Many tools run in your browser, and each card says when a tool uses the server or AI-assisted help. For the full capability map, see About.

Below, use search or category tabs to open a tool. Check the label on a card before pasting sensitive text. For saved shortcuts and automation, see About.

If these tools save you time, you can support ongoing updates—optional, and always appreciated.

Browse tools

Choose a category to narrow the list. The All tab shows a short preview first so the page stays easy to scan.

Common use cases

  • Pick a category when you know the kind of job—JSON, images, color, encoding, time, text, calculators—but not the exact tool name.
  • Use the execution label on each card before pasting anything sensitive. It tells you whether the main work runs in the browser, on the server, or with AI-assisted help.
  • For scripts, assistants, or IDE workflows, open the automation guide after you find the tool you want to hand off.

Common mistakes to avoid

  • Assuming every tool runs only in your browser

    Many tools run in the browser, but not all of them. Read the label on the card and the notes on the tool page before you paste private data.

  • Assuming this first list shows every page

    Some hubs have extra subtools. Use the search box, category tabs, or the tool map when you need something specific.
