AES Encryption Explained: How It Works and Why It Matters
Jun 23, 2026
Text encoding defines how characters are represented as bytes in computer systems. Different encodings use different byte sequences to represent the same text. Understanding encodings is essential for working with international text, APIs, databases, and file formats.
This tool supports three major encodings:
Encoding transforms data into a different format for interoperability (like UTF-8 bytes or hex), while encryption secures data so it cannot be read without a key. Encoding is reversible without a key and is not designed for security.
Different encodings represent the same characters using different byte sequences. For example, the character "é" is one byte (0xE9) in Latin1 but two bytes (0xC3 0xA9) in UTF-8. This tool lets you compare how the same text looks in different encodings.
You can view encoded bytes in four formats: Hex (48 65 6C), Percent (%48%65%6C, URL-style), Decimal (72 101 108), and Binary (01001000 01100101 01101100). All formats are space-separated for readability.
Yes. All processing happens entirely in your browser using JavaScript's built-in TextEncoder and TextDecoder APIs. Your data is never uploaded to any server, stored, or logged.
