Frequently Asked Questions

Why do some hex converters break when converting emojis or foreign languages?

Basic converters rely on legacy JavaScript functions like charCodeAt(), which only read 16-bit values. This causes errors with characters outside the basic multilingual plane, such as modern emojis. This converter uses full UTF-8 byte stream parsing to ensure all international scripts and emojis convert cleanly without errors.

What hex formats does the decoder accept?

The Hex → Text decoder dynamically cleans up input strings. It strips out spaces, commas, lines, and common developer prefixes like 0x or \x automatically before translating, meaning you can paste raw data arrays without manual formatting.

Is any of my input data sent to a cloud server?

No. Your privacy is fully protected. The tool uses local client-side JavaScript to perform all operations inside your web browser. No data is sent to a server, keeping your sensitive code and tokens safe.

How does the custom prefix formatting option work?

When you select the custom option in Text → Hex mode, the tool adds your specified text (like \x) to the front of every hex byte. This allows you to generate ready-to-use strings for programming languages like C, Python, or PHP instantly.

Is there a maximum size limit on the inputs I can paste?

There are no arbitrary software limitations on our platform. The engine easily handles text blocks up to several megabytes, limited only by your device's system memory and browser processing speeds.
