How to Use the Color Converter Online

Color Converter: before and after TEXT A YOUR INPUT COLORCONVERTER DONE A RESULT

Paste a colour in any common form, say #dc2020, rgb(220, 32, 32) or the name tomato, and Color Converter writes it out as HEX, RGB, RGBA, HSL and CMYK. It also shows the contrast ratio of that colour against black and against white text, graded AAA, AA or fails. Designers and front-end developers use it to move a brand colour between CSS, a design file and print.

Converts between HEX, RGB, HSL and CMYK, and checks contrast while it is at it. The conversions are exact arithmetic rather than lookup approximations, so a value round-trips unchanged. CMYK is the exception and always will be: it describes ink on paper rather than light on a screen, so the figure here is a standard conversion rather than what your printer will actually lay down.

Tips and Good to Know

  1. CMYK here is a standard formula, not your printer's profile. Ink on paper will differ, so check a printed proof before ordering.

  2. It grades contrast only against black and white. For two colours of your own choosing, a dedicated contrast checker is the right tool.

  3. It does not output HSV, LAB or OKLCH.

Frequently Asked Questions

Answers to common questions about this tool.

Do I need to install anything to use the Color Converter?

No. Color Converter runs entirely in your browser — there is nothing to download, no extension and no desktop program. It works the same on Windows, macOS, Linux, Android and iPhone.

Is it safe to use the Color Converter online?

Safer than the usual alternative, yes. Most online tools upload your file to a server you know nothing about, where it sits until someone deletes it. Here the file never leaves your device — the processing happens in the page itself, so there is no server copy to leak, retain or sell.

Is my text sent anywhere when I use Color Converter?

No. The text you paste is handled in your browser and never leaves the page. That makes it safe for drafts, customer lists and anything else you would rather keep to yourself.

Is there a limit on how much text I can paste?

The site sets none. Long documents are handled by your own device, so a whole book may be slow on an older phone. Articles, essays and long lists are no trouble.

Can I use Color Converter without making an account?

Yes. There is no login, no email to hand over and no daily limit. Open the page, paste or type, and copy or download the result when it is ready.

Why does my word count differ from Microsoft Word?

Programs treat hyphenated words, numbers and symbols a little differently. The gap is usually a few words in a long piece. If a teacher or portal sets a limit, stay a little under it to be safe.

Do the QR codes made here expire?

No. The information is stored directly in the pattern, with no redirect through our servers, so the code keeps working for as long as the link or text inside it stays valid.
