Number & encoding converter

Text / Binary / Hex Converter

Encode UTF-8 text into byte values or decode byte values back to text.

Direction

Encoded bytes

Enter values to calculate

Text encoding uses UTF-8 rather than assuming every character is one ASCII byte.

UTF-8 bytes

Text is encoded with UTF-8, so non-ASCII characters can require multiple bytes. Calling every byte sequence ASCII would be misleading.

Three byte displays

The same bytes can be shown in binary, hexadecimal, or decimal notation.

Decoding invalid sequences

When byte input is not valid UTF-8, the browser decoder may insert replacement characters instead of inventing a different character.

Frequently asked questions

Does conversion happen in my browser?

Yes. These value conversions run in the browser and do not require an account.

Should I verify a critical conversion?

Yes. For engineering, laboratory, medical, financial, legal, or safety-critical work, verify the unit definition and result against an authoritative standard for your context.
