Tools
| Tool | Description | Behaviour |
|---|---|---|
| base64 | Encode text (as UTF-8) to Base64, or decode Base64 back to text, and return the result. Decoding accepts standard and URL-safe alphabets and ignores whitespace; invalid Base64 returns an error. Bytes that are not valid UTF-8 are shown as replacement characters. Input up to 100 KB. | Read-only |
| convert_timestamp | Convert a Unix timestamp or a date to Unix seconds, Unix milliseconds, ISO 8601 (UTC), an HTTP-style UTC string and a readable date in the chosen time zone. Numbers with 13 or more digits are read as milliseconds, shorter ones as seconds. Dates without a time zone are read as UTC. Errors are returned for unreadable dates and unknown time zones. | Read-only |
| convert_units | Convert a number between two units of the same category and return a line such as "5 mi = 8.04672 km" (up to 10 significant digits). Units are matched by symbol or name, case-insensitive. Errors are returned for unknown units, units from another category, non-numeric values and temperatures below absolute zero. Months are 1/12 of a 365-day year. Units by category (symbols): length: m, km, mi, ft, in, cm, mm, yd, nmi; weight: kg, g, lb, oz, t, mg, st; temperature: °C, °F, K; volume: L, mL, gal, fl oz, cup, tbsp, m³; speed: km/h, mph, m/s, kn, ft/s; area: m², km², mi², ft², ac, ha; data: B, KB, MB, GB, TB, bit, KiB, MiB, GiB, TiB; time: s, min, h, d, wk, mo, yr, ms. | Read-only |
| count_words | Count words, characters (with and without spaces), sentences and paragraphs, and estimate reading time at 238 words per minute. Words are runs of letters or digits in any language; hyphenated words and contractions count once. Paragraphs are separated by blank lines. Input up to 100 KB. | Read-only |
| format_json | Validate JSON and return it pretty-printed or minified, optionally with object keys sorted A-Z (recursively; array order is kept). Returns the formatted JSON as text. Invalid JSON returns an error naming the problem and its position. Input up to 100 KB. | Read-only |
| generate_password | Generate random passwords with Node's cryptographically secure generator. Each enabled character set appears at least once and the result is shuffled. Returns one password per line; every call gives new results. An error is returned if all character sets are turned off. Passwords are not stored or logged. | Read-only |
| generate_qr_code | Make a static QR code for a link or any text, up to 800 UTF-8 bytes. Returns a 512 px PNG image plus the SVG markup. The data is stored in the code itself, so it never expires and needs no account. Light-on-dark colors are allowed, but some older scanners need dark on light. Errors are returned for empty text, content over 800 bytes, or colors that are not six-digit hex. | Read-only |
| generate_uuid | Generate random version 4 UUIDs (RFC 9562) in lowercase 8-4-4-4-12 form, one per line. Every call gives new values. | Read-only |
| hash_text | Hash text (encoded as UTF-8) and return a line such as 'sha256: ba78...' with the lowercase hex digest. The same input always gives the same hash. MD5 and SHA-1 are only for checksums, not security; do not use plain hashes to store passwords. Input up to 100 KB. | Read-only |
| test_regex | Run a JavaScript (ECMAScript) regular expression against text. Returns the match count and, for each match, the matched text, its 0-based index, numbered capture groups and named groups. Returns 'No matches.' when nothing matches. All matches are listed (the g flag is added automatically), up to 200. Invalid patterns or flags return an error explaining why; patterns that run longer than 0.5 seconds are stopped with an error. Text up to 100 KB. | Read-only |
