Base64 encode / decode
Encode text to Base64 and back, the right way round for emoji and accents. URL-safe variant, padding optional, both boxes live. (nothing gets uploaded.)
Little browser tools that each do one thing and then get out of your way. No sign-up, no upload, no nonsense. (One of them makes box clothes. Long story.)
Encode text to Base64 and back, the right way round for emoji and accents. URL-safe variant, padding optional, both boxes live. (nothing gets uploaded.)
Hash a password with bcrypt, or check one against a hash, at a cost factor you choose. Pure browser, so the secret you paste stays with you.
Measure a telescoping board game box, get back DXF cutting templates for the four paper wraps. Ready for the cutter, in millimetres.
Punch in a colour as HEX, RGB, or HSL and watch the other two keep up. Live swatch, alpha, and a contrast check against black and white.
Type something and see its MD5, SHA-1, SHA-256, and SHA-512 at once, updating as you go. Copy any row. (md5 is for checksums, not secrets.)
Prettify, minify, and convert between JSON and YAML, with parse errors that actually tell you where it went wrong.
Paste a JSON Web Token and read its header and payload, with the dates spelled out and an expired-or-not badge. Optional HS256 check, all local.
Placeholder text by the paragraph, sentence, or word. Comes in classic Latin or a crayon-flavoured nonsense mode of our own.
Turn a link or some text into a QR code and grab it as PNG, JPG, or SVG. Download it or copy it to the clipboard. Stays in your browser.
Test a regular expression against some text, with live highlights, capture groups, and a replace preview. Bad patterns get a polite error, not a crash.
Paste some text and get the counts: characters, words, bytes, sentences, reading time, readability, and what it is quietly made of. (emoji ratio included.)
Paste two blocks of text and see what changed, line by line. Ignore whitespace or case if you like, with a tally of what moved.
Convert between Unix epoch and human dates, in local time and UTC. Guesses seconds from milliseconds, and ticks along live.
Percent-encode and decode URL bits, with both encodeURIComponent and encodeURI on offer (people reach for the wrong one). Breaks a query string down too.
Generate UUIDs, one or a hundred, v4 or time-ordered v7. Uppercase, hyphenless, or wrapped, then copy the lot.
More tools as the need (or the boredom) strikes.
