The toolkit behind every website
Building and running a site is a hundred small tasks — tidying a blob of JSON, shrinking a stylesheet, encoding a URL, generating the SEO files that get you found on Google. None of them are hard, but hunting for a clean tool each time is friction. This hub keeps the essentials in one place, running privately in your browser (with one clearly-marked exception).
Formatting & minifying
The JSON formatter re-indents messy data into readable structure and validates it, pointing to errors when the JSON is broken. The minifier does the opposite for CSS and JS — stripping comments and whitespace so files download faster, which directly helps page speed.
Encoding & decoding
URL encoding makes text safe to put in a web address; Base64 reformats data (like images or tokens) into plain text that travels cleanly through systems.
SEO generators — get found on Google
These are the same building blocks behind good search visibility:
- Meta tags — the title and description search engines show in results. Well-written ones lift click-through rates.
- robots.txt — tells crawlers which parts of your site they may or may not visit.
- XML sitemap — a list of your important URLs so search engines can discover and index every page, not just the ones they stumble on.
Paste a list of URLs into the sitemap generator and it produces valid XML you can drop straight into your site and submit to Google Search Console.
Handy extras
A QR code generator for links and text, an IP lookup to see your public address (this one queries an external service by design), and a UUID generator for unique identifiers developers need constantly.
Frequently asked questions
What does the JSON formatter do?
Re-indents messy or minified JSON into clean, readable structure and validates it, flagging where any errors are.
Is Base64 secure?
No. Encoding like Base64 and URL encoding is reversible and offers no secrecy — it's for compatibility, not security. Don't use it to hide sensitive data.
How do these help SEO?
Meta tags set your title/description, robots.txt guides crawlers, and an XML sitemap lists your URLs so search engines can index them.
Is my data private?
Yes, except the IP lookup, which by design asks an external service for your public IP. Everything else runs in your browser.
What is a UUID?
A 128-bit universally unique identifier used to label records, files or sessions with virtually no chance of collision.
Tools are provided for general development use and run in your browser (except IP lookup). Always test generated files on your own site before relying on them.
