TOTP Generator/Verifier

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.

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.

HMAC Generator

Compute HMAC (Hash-based Message Authentication Code) of text or a file with a secret key — eight algorithms at once: MD5, SHA-1, SHA-256, SHA-384, SHA-512, SHA3-256, SHA3-512, RIPEMD-160.

Bcrypt Hash + Verify

Hash passwords with bcrypt (random salt, adjustable cost) and verify a password against an existing bcrypt hash.

UUID Generator

Generate UUID versions 1, 3, 4, 5, 6 and 7 — random, time-based, and name-based.

Password Generator

Cryptographically random passwords with configurable length and character set.

Cron Parser

Parse a cron expression (5 or 6 fields, including @-shortcuts) — a plain-language schedule description and next run times in a chosen time zone.

Markdown Preview / HTML ↔ Markdown

Live preview of Markdown as formatted HTML, plus two-way conversion: Markdown → HTML and HTML → Markdown.

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.

JSON ↔ YAML / CSV / XML / TOML

Convert JSON to YAML, CSV, XML, or TOML and back — entirely in the browser, no libraries.

Character & Word Counter

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

URL Encode/Decode

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