Yes, your security and privacy are our top priorities. All processing and calculations for our developer tools are performed client-side, directly in your browser. No data, code, or configuration is ever sent to our servers.
Our browser-based tools are designed for speed and convenience. They are perfect for quick, one-off tasks like formatting a JSON snippet, decoding a Base64 string, or generating a UUID without needing to switch contexts or open a full-fledged application.
A UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify information in computer systems. Developers use them for creating unique database keys, transaction IDs, and more, where ensuring uniqueness is critical.
Our tool is optimized for performance and can handle most common JSON file sizes efficiently. However, for extremely large files (e.g., over 10MB), using a dedicated local code editor might provide a better experience.
The Regex Tester utilizes the standard JavaScript regular expression engine that is built into your browser. This syntax is widely used and highly compatible with many other programming languages and environments.
