Text tools

Text tools are the ones you reach for mid-task: a word count for a brief, a JSON blob that needs to be readable, two drafts that need comparing. Each of these free online text tools works on the content in the box in front of you, updating as you type, with nothing sent anywhere.

• Word counter and character counter — live word, character, sentence and paragraph counts with reading-time estimates for essays, meta descriptions and social posts.
• JSON formatter and validator — beautify, validate and minify JSON with the exact position of any syntax error, even on multi-megabyte API responses.
• Text diff checker — compare two versions of a document, contract or config file and see every addition, deletion and edit highlighted.
• Case converter and slug generator — switch between Title Case, sentence case, camelCase and snake_case, and turn any headline into an SEO-friendly URL.
• CSS and JavaScript minifiers — compress stylesheets and scripts before deployment to cut render-blocking bytes and improve Core Web Vitals.

All free, all unlimited, and all processed in your browser — so unpublished drafts and internal code never leave your machine.
