- Base64 ConverterEncode text to Base64 or decode Base64 back to readable text, with a plain message when the input will not decode rather than a wrong answer.
- Binary ConverterConvert text to binary, or turn groups of eight 0s and 1s back into text — useful for teaching, puzzles, and seeing what a byte actually holds.
- Case ConverterConvert text to lowercase, UPPERCASE, Title Case or Sentence case without retyping it, leaving the words and punctuation exactly as they were.
- Lorem Ipsum GeneratorGenerate placeholder paragraphs, sentences or words for a layout, up to five hundred at a time, so a design is judged on its shape and not its copy.
- MD5 GeneratorProduce the MD5 hash of any text as a 32-character hex string, for checksums, cache keys, and matching a value another system already recorded.
- Number GeneratorGenerate random whole numbers within a range you set, up to ten thousand at a time, one per line and ready to paste somewhere else.
- Password GeneratorGenerate a random password between 4 and 256 characters from mixed-case letters and digits, made fresh for the request and saved nowhere.
- Text CleanerCollapse every run of spaces, tabs and line breaks into single spaces and trim the ends, turning text pasted from a PDF or an email into one clean line.
- Text ReplacerFind and replace every occurrence of a string in a block of text at once, matched exactly as typed, with no pattern syntax to learn or get wrong.
- Text ReverserReverse a block of text so it reads back to front, character by character — handy for word games, palindrome checks and testing text handling.
- Text to Slug ConverterTurn a title into a clean URL slug: lowercased, with every run of spaces and punctuation collapsed into a single hyphen.
- Uptime CalculatorWork out an uptime percentage from a period and its downtime, and see how much downtime a 99.9% target would actually allow over that same period.
- URL ConverterPercent-encode text so it survives a query string, or decode %20-style escapes back into the characters they stand for.
- URL ParserBreak a URL into its scheme, host, port, path, query and fragment, and list every query parameter separately with its decoded value.
- UTM BuilderBuild a campaign URL with correctly encoded utm_source, utm_medium and utm_campaign values, plus optional term and content, ready to paste into a link.
- UUID GeneratorGenerate random version 4 UUIDs, up to five hundred at a time, one per line — identifiers unique enough that nobody has to hand them out.
- Word CounterCount characters, characters without spaces, words, sentences and paragraphs at once, so a piece can be checked against the length limit it has to meet.
- Word Density CounterMeasure which words and phrases a text repeats most, as a count and a share of the whole, for phrases of one to five words.
- Color ConverterConvert a hex colour to its RGB and HSL equivalents, so one colour can be written in whichever notation a stylesheet or a design tool expects.
- CSS MinifierStrip comments and unnecessary whitespace from CSS to make the file smaller, without changing which rules apply or the order they apply in.
- HTML MinifierRemove comments and collapse the whitespace between HTML tags to cut a page's size, leaving the markup and its visible content intact.
- IDN ConverterConvert an internationalised domain between its Unicode spelling and its Punycode xn-- form, the way a browser and DNS each store the same name.
- JS MinifierStrip comments and redundant whitespace from JavaScript to reduce its size, leaving the code and everything it does unchanged.
- JSON ValidatorCheck whether JSON is valid and, when it is not, get the exact line and column where parsing stopped — plus a pretty-printed copy when it is.
- QR GeneratorTurn a URL or any text into a QR code as a sharp SVG, at the size you choose, with four levels of error correction to pick from.
- User Agent ParserRead a user agent string and get the browser, its version, the operating system, the device type, and whether the client is a bot.
- DNS LookupLook up a domain's DNS records live — addresses, mail, name servers, text and more — and see what resolvers are answering for it right now.
- Domain IP LookupFind the IPv4 and IPv6 addresses a domain currently resolves to, labelled by record type, so you can see where its traffic is really being sent.
- HTTP Headers CheckerFetch a URL's status and every HTTP header it returns, so caching, security and content-type headers can be read as the server actually sends them.
- IP LookupCheck an IP address: which version it is, whether it is routable on the public internet or reserved, and what name it resolves back to.
- Meta Tags CheckerRead a page's title, description, canonical, robots, viewport, H1 and Open Graph tags as served, with the character counts that decide truncation.
- Redirect CheckerFollow a URL's redirects hop by hop, up to ten, showing each status code and destination and where the chain finally lands.
- Reverse IP LookupAsk what host names an IP address points back to through its PTR records — the reverse of an ordinary DNS lookup.
- SSL CheckerInspect a site's TLS certificate: days remaining, whether it covers the name you visited, who issued it, and every other name it is valid for.
- Website Status CheckerCheck whether a URL is up: the status code it returns, the address it finally settled on, and how many milliseconds the server took to answer.
- WHOIS LookupLook up a domain's WHOIS record — registrar, creation and expiry dates, name servers and status — exactly as the registry returns it.
