Text & Developer Tools FAQs
Common questions about these utilities.
No. These tools run entirely in your browser with JavaScript. Once the page has loaded, they keep working even without an internet connection.
The Regex Tester, Base64, URL and JSON tools use the browser's JavaScript engine, so results match JavaScript and Node.js. Other languages can differ in details, such as regex syntax or URL-encoding rules.
Format it with the JSON Formatter, decode the access token with the JWT Decoder and convert any timestamps with the Unix Timestamp Converter.
Yes. Both use the browser's cryptographically secure random generator (crypto.getRandomValues and crypto.randomUUID), not Math.random.
