Small tools that do one thing properly. Count words and reading time, convert text between nine cases, format and validate JSON, generate hashes, passwords and UUIDs, encode Base64 and URLs, compare two texts, and turn headlines into clean URL slugs.
Every tool runs in your browser and updates as you type — nothing is uploaded, nothing is logged, and no account is required. Paste a production API response or an unpublished draft without it leaving your device.
Generate QR codes for URLs, text, Wi-Fi and more.
Count words, characters, sentences and reading time as you type.
Convert text between UPPER, lower, Title, camelCase, snake_case and more.

No. Every tool here runs in your browser with JavaScript, so API responses, access tokens, contracts and unpublished drafts never leave your device.
No. Every text and developer tool is free to use with no sign-up, no watermarks and no limits worth worrying about.
MD5 has been broken for collision resistance since 2004 and browsers deliberately do not ship it. SHA-256 is the safe default and is what modern checksums use.
