Convert Bytes to String online for free

What is Bytes to String?

Bytes to String is a powerful online decoder that converts hexadecimal byte sequences back into readable text. It uses UTF-8 decoding to ensure that all characters, including Emojis, multi-language text (Chinese, Japanese, etc.), and special symbols, are restored correctly.

This tool accompanies our String to Bytes Converter, allowing you to seamlessly switch between text and hex representations. It performs the reverse operation, designed to help developers analyze binary data, debug network traffic, or interpret hex dumps.

How to use

1. Enter Hex Bytes: Paste your byte sequence into the input box. The tool automatically detects common formats.
2. View Result: The decoded text string appears instantly in the output box.
3. Custom Delimiter (Optional):
   • By default, the tool Auto Detects delimiters (spaces, commas, colons, 0x, \x, etc.).
   • You can check Use Custom Delimiter to specify a unique separator if your data uses a non-standard format.

Examples

Why use Bytes to String?

1. Hex Dump Analysis

Translate hex dumps from wireshark, log files, or memory snapshots back into human-readable text to understand the content. Example: Decoding 45 72 72 6f 72 to see it means “Error”.

2. Python Byte Decoding

Convert Python byte strings (e.g., printed as hex) back to normal strings without writing code. Example: Quickly verify what b'\xe4\xbd\xa0' represents.

3. Debugging Encoding

Verify if a byte sequence is valid UTF-8. If the bytes were encoded incorrectly or using a different charset (like Latin-1), the output might look garbled, helping you diagnose encoding mismatches.

4. CTF & Security

Useful for Capture The Flag (CTF) challenges and security research where hidden messages are often encoded in hex.

How it works

The tool cleans your input by removing prefixes like 0x or \x and separators. It then parses the remaining hexadecimal digits into a byte array. Finally, it uses the browser’s standard TextDecoder API (set to UTF-8) to decode the bytes into a string. This safeguards against common manual decoding errors involving multi-byte characters.

FAQ

Does it support different encodings (ASCII, UTF-16)?

Currently, it uses UTF-8, which is backward compatible with ASCII. If your bytes are pure ASCII, they will decode correctly. For UTF-16 or legacy encodings (like Windows-1252), the result may not be accurate if the bytes represent characters outside the ASCII range.

Can I paste format like \x48\x65?

Yes! The tool is smart enough to handle and strip common prefixes like \\x, 0x, % (URL encoded), and various delimiters automatically.

Is my data safe?

Absolutely. All conversion happens locally in your browser using JavaScript. No data is ever sent to our servers.
