Use free developer tools for JSON, XML, CSS, JS, HTML, JWT, cron, hashes, encoders, minifiers, beautifiers, and converters.
Developer Tools for fast browser workflows
Developer tools on ToolsMagicPro focus on quick formatting, validation, encoding, decoding, conversion, inspection, and cleanup tasks. The hub includes JSON, XML, CSS, JavaScript, HTML, JWT, cron, hash, binary, HEX, ASCII, QR, barcode, and unit workflows. These tools are useful during debugging, QA, content publishing, and small automation tasks where a browser utility is faster than opening a full IDE.
Start with the most relevant tool, complete the task, then move through related category links when your workflow needs another converter, checker, generator, or calculator. The index is built for users who want direct tool access without opening unrelated pages first.
For SEO and domain tasks, begin with URL-based checks and move into sitemap, robots, schema, link, or crawler tools. For file work, choose the exact source and target format before uploading. For calculators, review every assumption before treating the result as a planning number.
How to choose
Pick by input type first, then by output format. URL tools inspect public pages, converter tools transform pasted text or files, and calculators estimate results from editable assumptions.
