Is my text uploaded anywhere?

No. Conversion runs entirely in your browser using JavaScript. Your text is never uploaded, logged, or transmitted — there is no account and no server call.

How is non-ASCII text handled?

Text is first encoded to UTF-8 bytes, then each byte is written as two lowercase hex digits. So characters like ₹ or emoji become their multi-byte UTF-8 representation, and decoding reverses it exactly — no data is lost.

What hex input can I decode?

Spaced (48 65 6c), continuous (48656c), and 0x-prefixed input are all accepted; whitespace and 0x prefixes are ignored. The digit count must be even (two per byte) and only 0–9 / a–f are allowed, otherwise a clear error is shown.

Is hex the same as encryption?

No. Hexadecimal is a representation of bytes, not encryption — anyone can convert it straight back to text. It provides no confidentiality.

Hex Converter

Convert text to hexadecimal and hex back to text, in your browser. Text is encoded as its UTF-8 bytes in lowercase hex, and decoding accepts spaced, continuous, or 0x-prefixed input. Nothing is ever uploaded.

How this works & your privacy

🔒 Nothing you paste, type, or drop is uploaded, stored, or logged. All processing happens in your browser and the data never leaves your device — close the tab and it is gone.

Encoding converts text to UTF-8 bytes and writes each byte as two lowercase hexadecimal digits (space-separated for readability). Decoding accepts spaced, continuous, or 0x-prefixed hex, validates the digits, and reconstructs the UTF-8 bytes back to text. Pure and byte-accurate.

Limitations

Hexadecimal is a representation, not encryption — it provides no confidentiality.
Decoding requires an even number of hex digits (two per byte) and only 0–9 / a–f; anything else is reported as an error rather than producing garbage.
