About Color Tools

Color Tools is a free, privacy-first online tool. An all-in-one color toolkit: color picker, palette generator, HEX/RGB/HSL/CMYK converter, and WCAG contrast checker. Free, fast, and works great on mobile.

Why we built it

Most popular tools in this category force you to upload your files to a remote server, then cap how many you can process, slow you down behind paywalls, or bury the tool under intrusive ads. We took a different approach: every operation happens locally in your browser. That means no upload waits, no file-size limits, no daily quotas, and your data never leaves your device.

How we keep it free

This site is supported by a small number of non-intrusive ads. That's it — no subscriptions, no "premium" gating of core features, no surprise charges.
