Text Tools

A toolbox for writers, developers and students. Format and validate JSON, count words and characters, change text case, encode and decode Base64, URL and HTML, convert Markdown, test regular expressions, compare two texts, clean up lists, and convert legacy fonts to Unicode — all instantly in your browser.

Tools for writing and for code

On one side you'll find writing helpers — word counter, case converter, find and replace, sort and deduplicate lines, keyword density. On the other are developer utilities — JSON formatter, Base64 and URL encoders, Markdown and HTML converters, and a live regex tester. Together they cover the small text jobs that come up every day.

Instant, private and unlimited

Every text tool runs entirely in your browser, so whatever you paste — notes, code, data or documents — never leaves your device and is never uploaded to a server. There are no limits and no sign-up: paste your text, get the result immediately, and copy it straight back into your work.
