Free Online Tools for Developers, Security & Productivity

Developer Utilities

FindBeam's developer tools include a CSS minifier, JavaScript minifier, HTML minifier, JSON formatter and validator, and Base64 encoder. Each tool compresses, formats, or transforms your code entirely in the browser — no files are uploaded to any server. Ideal for front-end developers, DevOps engineers, and anyone optimising web performance.

Security & Hashing

The security tools include a cryptographically strong password generator, SHA-256 and SHA-512 hash generators, and an MD5 hash generator and verifier for checksums and legacy compatibility. Passwords are generated using the browser's crypto.getRandomValues() API — they are never transmitted, logged, or stored.

Text & Writing Tools

Text tools cover word and character counting, case conversion (camelCase, PascalCase, snake_case, kebab-case and more), and a lorem ipsum generator for design mockups. Useful for writers, students, content creators, and developers needing placeholder text or quick text analysis.

Health, Network & More

The platform also includes a BMI calculator, IP address lookup, internet speed test, and a YouTube thumbnail downloader. New tools are added regularly across finance, health, image, and productivity categories — all free, all browser-based, with no account required.

How does the CSS minifier work? +

FindBeam's CSS minifier runs entirely in your browser. Paste your CSS code into the tool, click Minify, and it instantly removes whitespace, comments, and redundant declarations to produce a compressed stylesheet.

You can generate passwords of any length with custom character sets — uppercase, lowercase, numbers, and symbols — entirely offline.
