Sort lines of text alphabetically, remove duplicates, empty lines, and extra whitespace.

CRLF ↔ LF Converter

Convert line endings between Windows (CRLF), Unix/macOS (LF), and classic Mac (CR), with mixed-ending detection.

Character & Word Counter

Real-time text statistics: characters (with and without spaces), words, lines, sentences, paragraphs, and size in bytes (UTF-8).

Checksum Verifier

Verify the integrity of a file or text — paste the expected hash and the tool will detect the algorithm among 13 supported ones.

Hash Generator

Compute hashes of text or a file with thirteen algorithms at once: MD5, SHA-1, SHA-256, SHA-384, SHA-512, SHA3-256, SHA3-512, RIPEMD-160, BLAKE2b, BLAKE2s, BLAKE3, CRC32, and Adler-32.

Color Converter

Convert colors between HEX, RGB, HSL, HSV/HSB, and CMYK — enter a value into any field and the rest update instantly.

AES Encrypt/Decrypt

Encrypt and decrypt text with AES-GCM or AES-CBC using a password (key derived via PBKDF2).

URL Encode/Decode

Encode and decode URLs — characters that need escaping in links and query parameters.

HTML Entities Encode/Decode

Encode and decode HTML entities — safely display special characters on a page.
