Slugify

Case Converter

Convert text or an identifier into every common naming style at once — camelCase, snake_case, kebab-case, and more. Recognizes word boundaries in camelCase/PascalCase, acronyms (XMLParser → XML + Parser), and around digits.

Text Diff

Compare two texts line by line — what was added, removed, or changed, with word-level highlighting inside changed lines.

Test regular expressions against real text: highlighted matches with parsed capture groups, or replace matches with new text.

Sort & Dedupe Lines

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

String Escape

Escape text into a string literal (quotes, backslash, control characters) for pasting into code, or unescape it back.

CRLF ↔ LF Converter

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

AES Encrypt/Decrypt

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

Age Calculator

Exact age from a birth date — years/months/days, total time lived, and the next birthday.

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.

Placeholder Image Generator

Generate a placeholder image of a given size for mockups and layout.

Query String ↔ JSON

Parse a URL query string into a JSON object, or build a query string back from JSON.
