What it can do
13 tools, in the server's own words.
find_toolread-onlyFind a free online tool on CodeKitHub (there are hundreds: converters, calculators, generators, text, code and image tools).
convert_unitsread-onlyConvert between units of length, mass, volume, area, speed, time, data size and temperature, e.g.
calculate_ageread-onlyExact age from a birth date: years, months, days, total days and days until the next birthday.
date_differenceread-onlyDays, weeks and calendar years/months/days between two dates.
calculate_percentageread-onlyPercentage maths.
compound_interestread-onlyCompound interest with optional monthly contributions: final balance, total contributed and interest earned.
text_statsread-onlyCount characters, words, sentences, paragraphs and lines, and estimate reading time.
convert_caseread-onlyChange text case: upper, lower, title, sentence, camel, pascal, snake, kebab or constant.
encode_decoderead-onlyEncode or decode text: Base64, URL, HTML entities, hex.
hash_textread-onlySHA hash of a text (SHA-1, SHA-256, SHA-384, SHA-512).
json_toolsread-onlyFormat, minify or validate JSON.
timestamp_convertread-onlyConvert a Unix timestamp (seconds or milliseconds) or an ISO date to both forms; "now" gives the current time.
