Why browser-based tools matter
Developers often paste API responses, tokens and configuration into online formatters without thinking about where that data goes. Every tool on this page works locally in your browser, using standard web APIs such as the Web Crypto API for passwords. Nothing you type is sent to our server.
For website owners, pair these with our SEO tools: generate schema markup, then tidy it with the JSON formatter, or create a favicon and check your meta tags.
