Generate cryptographically secure secrets for .env files, and AES-128/192/256 keys in hex, base64 or base64url.

Generate RFC 9562 version 4 and time-ordered version 7 identifiers, one at a time or in bulk.

Encode and decode standard Base64 and Base64URL, for text or binary files, without the data leaving your tab.

Compute SHA-256, SHA-384, SHA-512, SHA-1 and MD5 digests of text or files, locally in your browser.

Convert between Unix seconds, milliseconds, ISO 8601 and readable dates in any timezone — or just ask for the current time.

Format, minify, validate, sort, escape and unescape JSON without rewriting a single number.

Decode a JSON Web Token's header, claims and expiry locally. Decoding only — signatures are never verified.

Percent-encode and decode across four named escape sets, parse a URL into its parts, and read or build query strings.

Compare two texts line by line, or two JSON documents semantically, and export a unified diff that applies cleanly.

Generate Diceware passphrases you can actually remember, or character passwords with honest entropy — never rounded up.

Work out network, broadcast, usable range, masks and host counts for any IPv4 or IPv6 block — exact even at /64.

Explain a cron expression in English and list its next runs in any timezone — including the day-of-month/day-of-week OR rule that catches everyone.

Turn text, a URL or a wifi string into a QR code — as SVG in the browser, or drawn scannably straight into your terminal.

Convert between any bases from 2 to 36, with two's-complement fields and byte layouts — exact past 2^53, where a calculator starts rounding.

HTML character references, Unicode escapes, hex and binary views of text — with an honest account of where each escaping is actually safe.

Integers, floats, booleans, hex bytes, random picks and unbiased shuffles for test data — never for credentials.

Test JavaScript regular expressions against sample text with live matches, capture groups and a replace preview.
