Encoding tools

Encoding represents the same data in a different form. Unlike encryption, encoding needs no key and provides no security. It exists to move bytes safely through systems that only accept text.

Hex

Hex Encode

Encode text or bytes to hexadecimal.

Hex Decode

Decode hexadecimal back to text.

Hex Dump

Display any input as a hex dump with offsets and ASCII.

Hex Encode File

Encode any file as hex in your browser. Drop a file, get the hex text.

Hex Decode File

Decode hex text back to a file. Download the result.

Binary

Text to Binary Converter

Convert text to binary and binary to text. UTF-8, ASCII, and UTF-16.

Base32

Base32 Encode

Encode text or bytes to Base32.

Base32 Decode

Decode Base32 back to text.

HTML

Classical

ROT13

Encode and decode ROT13, ROT5, ROT18, and ROT47 - the classic letter-rotation ciphers.

Caesar Cipher

Encode and decode the Caesar cipher with any shift from 1 to 25, including ROT-N variants.

About encoding tools

Base64 packs 3 bytes into 4 characters and is used everywhere: email attachments, JSON Web Tokens, data URIs, and API payloads. The URL-safe variant replaces + and / with - and _ so tokens survive being placed in URLs.

Base32 is less compact but case-insensitive and avoids look-alike characters, which is why it appears in TOTP secrets and DNS records. Hex (Base16) doubles the size but is trivially readable and comparable by eye, making it the standard for hash outputs and MAC addresses.

URL and HTML encodings protect content from being misinterpreted by parsers. Percent-encoding keeps reserved characters out of URL paths and query strings. HTML entity encoding prevents user content from being treated as markup. Both are essential for building anything that handles untrusted input.
