Is this color converter completely free?

Yes. No account, no payment, no subscription. The tool is free and always will be.

Do I need to upload anything to convert colors?

No. Color conversion is pure mathematics — no file, no image, nothing is uploaded. Everything runs in JavaScript in your browser. No data ever leaves your device.

What color formats does it support?

HEX (#rrggbb and shorthand #rgb), RGB (rgb() function or raw values), HSL (hsl() function), and OKLCH (oklch() function). All four formats are converted simultaneously with a live preview.

Can I use it on mobile?

Yes. The tool is fully responsive and works on any device with a modern browser — phone, tablet, or desktop.

What makes a good free color converter?

Many color converters online require an account, show intrusive ads, or run server-side (meaning your values are sent to a third-party). Flowfiles' color converter runs entirely in your browser: type a color, get the result instantly with zero network requests. It supports all four formats a modern CSS developer needs — HEX, RGB, HSL, and OKLCH — with a live color swatch and one-click copy for each format.

Yes, completely. No payment, no subscription, no freemium limit. The tool is free to use without any restriction.
