About Text & Code tools

A fast, private workbench for anyone who works with text and code. Etoolio lets you encode and decode Base64 or URLs, format and minify JSON, generate hashes, count words and characters, convert case, compare two versions line by line, test regular expressions, and clean up messy Markdown — all in the browser. Nothing you paste is sent anywhere or logged, which matters when you're handling snippets from real projects, configs, or documents. Because everything runs client-side, results appear the instant you type and keep working even offline once the page has loaded. Developers, writers, students, and support teams use these to shave the friction off small recurring tasks, with no extensions to install, no usage limits, and no sign-up.
