About Utility369
Utility369 is a collection of 155+ free online tools for text editing, SEO, CSS, coding and social content, all built to run entirely in your browser. There's nothing to install and nothing to sign up for.
Every tool on this site processes your input directly on your device using JavaScript. We don't upload your text, code or files to a server to make a tool work, so what you paste or type stays on your own machine.
Why we built this
Most "free" tool sites bury simple utilities behind sign-up walls, watermarks, or artificial usage limits. We wanted a place where a word counter, a JSON formatter, or a CSS gradient generator just works, instantly, with no friction, every time you need it.
What you'll find here
- Text, counters, converters, formatters and editing utilities for any text.
- SEO, meta tag generators, sitemap builders, keyword and on-page checkers.
- CSS, gradient, shadow, glassmorphism and SVG generators with live preview.
- Coding, formatters, minifiers, encoders and other developer utilities.
- Social/Viral, shareable content generators and thumbnail grabbers.
A small number of tools are clearly labeled (Fake) or (Fun), these are novelty generators (like fake chat screenshots) meant for entertainment, not real utilities. Everything else does exactly what its name says.
