Encoding & Decoding
Encode and decode Base64, URL, HTML entities, hex, binary, ROT13, Morse code, and more. Convert between CSV and JSON formats, generate MD5 hashes, create URL slugs, and inspect UTF-8 byte representations. All encoding tools run client-side for maximum privacy with sensitive data.
Base64 Encoder / Decoder
{}Encode text to Base64 or decode Base64 strings back to plain text instantly. Free online Base64 conversion tool with full Unicode support.
URL Encoder / Decoder
{}Encode special characters for URLs or decode percent-encoded URL strings back to readable text. Free online URL encoding tool.
HTML Entity Encoder / Decoder
{}Encode special characters as HTML entities or decode HTML entities back to characters. Prevent XSS and display special symbols safely.
Hex to Text / Text to Hex Converter
{}Convert text to hexadecimal representation or decode hex values back to readable text. Supports multiple separator formats.
Binary to Text / Text to Binary Converter
{}Convert text to binary (0s and 1s) or decode binary strings back to readable text. 8-bit binary representation with optional separators.
ROT13 Encoder / Decoder
{}Apply ROT13 cipher to text — shift each letter by 13 positions. Applying ROT13 twice returns the original text.
MD5 Hash Generator
{}Generate MD5 hash digests from any text input. Produces a 128-bit hexadecimal fingerprint for checksums and data verification.
Morse Code Translator
{}Convert text to Morse code (dots and dashes) or decode Morse code back to text. Supports letters, numbers, and common punctuation.
URL Slug Generator
{}Convert text to clean URL slugs — lowercase, hyphen-separated, with special characters removed. Perfect for creating SEO-friendly URLs.
CSV to JSON Converter
{}Convert CSV data to JSON format instantly. Parses headers as keys, handles quoted fields and commas within values.
JSON to CSV Converter
{}Convert JSON arrays of objects to CSV format. Extracts keys as headers and values as rows with proper escaping.
UTF-8 Byte Inspector
{}Inspect the UTF-8 byte representation and Unicode code points of each character in your text. Useful for debugging encoding issues.
