Text & Data tools
Counting, formatting and generating.
Tools for people who work with words and structured data: writers checking an essay against a word limit, developers debugging a JSON payload or decoding a JWT, anyone comparing two versions of a document to find what actually changed.
Because everything runs in your browser, these are safe for content you would not paste into an unknown website: production API responses, unpublished drafts, access tokens. The page never transmits your text. Disconnect from the internet after it loads and every tool keeps working.
Count words, characters, sentences and paragraphs instantly, with reading time, keyword frequency and social media character limits.
Pretty-print, validate and minify JSON in your browser. Pinpoints syntax errors by line and column. Nothing is uploaded.
Generate lorem ipsum placeholder text by paragraphs, sentences or words, with optional HTML paragraph tags. Instant, free, copy with one click.
Encode text to Base64 or decode Base64 back to text, with full Unicode and URL-safe support. Runs in your browser — nothing is sent anywhere.
Percent-encode text for URLs and query strings, or decode encoded URLs back to readable text. Handles UTF-8 and the component vs full-URL distinction.
Compute MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes of any text or file checksum, instantly in your browser. Nothing is uploaded.
Decode a JSON Web Token to see its header, payload and expiry time, without sending it anywhere. Highlights expired tokens and standard claims.
Compare two blocks of text or code and see added and removed lines highlighted side by side. Private, in-browser, with optional whitespace ignoring.
