Frequently Asked Questions
What types of conversions are supported?
We support 50+ converters across 8 categories: Security (password & hash generators), Text Tools (case converter, word counter, QR codes), Encoding (Base64, URL, HTML entities), Developer Tools (JSON, CSV, XML, YAML formatters), Color (RGBA, HEX, HSL, RGB), Number Systems (binary, decimal, hex, octal), Time (time zones, 12h/24h), and Unit Conversions (temperature, length, weight, volume).
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?
Most converter tools support real-time conversion as you type, making it easy to convert multiple values quickly. Some tools like the JSON Formatter and CSV to JSON converter can handle batch data in a single operation.
