Guide & best practices
Hex Converter and Checksum for bytes and checksums
Convert hex to text/bytes and back, account for endianness and verify integrity via checksums.
Typical use cases
Useful for low-level debugging, protocol analysis, firmware/binary data and file integrity checks.
How Balou converts hex
Enter hex or text and choose direction and encoding; Balou converts locally and optionally computes a checksum.
Checksum best practices
Mind the right encoding (UTF-8), consider endianness for multi-byte values and compare checksums against the source.
Frequently asked questions
How do I convert hex ↔ text?
Paste hex (e.g. 48656C6C6F) to get the text (Hello) or vice versa, based on the selected encoding.
What is a CRC32 checksum?
A fast, non-cryptographic checksum to detect random transmission or storage errors.
What does endianness mean?
The byte order of multi-byte values: big-endian stores the most significant byte first, little-endian last.
Is my data sent anywhere?
No, conversion and computation run locally in the browser.
