Frequently Asked Questions
What types of conversions are supported?
Available tools cover password and hash generation, text case and word counting, Lorem Ipsum, QR codes, ASCII, Base64 and URL encoding, hexadecimal text, CSV and JSON, UUIDs, regular expressions, PX and REM, escaped newlines, Unix timestamps, RGBA and HEX, number systems, Roman numerals, and EST-to-CST conversion.
Are conversions done locally or on a server?
All conversions happen entirely in your browser using JavaScript — no data is ever sent to a server. This means your data stays private and conversions work even without an internet connection after the page loads.
Can I convert multiple values at once?
Many tools update results as you type. Data tools such as CSV to JSON and JSON to CSV also accept pasted multi-row content for conversion in one operation.
What developer tools are available?
Developer tools include UUID generation, regular-expression testing, CSV to JSON, JSON to CSV, PX to REM, REM to PX, escaped-newline conversion, and Unix timestamp conversion.
