Developer Utilities That Don't Get in Your Way

Developers have enough friction in their day. That's why these tools are designed to be fast, predictable, and private. Convert binary to text, minify CSS and JavaScript, generate SHA hashes, extract emails or URLs, or convert a code screenshot into editable text—all without leaving your browser.

The CSV-JSON converter handles messy data with ease, while the Unix timestamp converter is a lifesaver when you're debugging logs. The robots.txt generator helps you set up crawling rules in seconds, and the lorem ipsum generator gives you realistic placeholder text when you need it.

No accounts, no uploads, no servers. Just utilities that solve a problem and get out of your way.
