How to use the Color Converter

  1. Pick a colour or type any format.
  2. Copy HEX, RGB, HSL or HSV.
  3. Grab a shade from the palette and check contrast.

Easy to use

Drop files, pick options, download. Whole folders at once, no signup, no daily limit.

Best quality

The same engines the professionals use — SVGO, resvg, MozJPEG, libwebp, libavif — compiled to run in your browser.

Private & secure

Files are processed on your device and never uploaded. Close the tab and nothing remains anywhere.

Every colour format, and readable contrast

Type or pick a colour and instantly get it as HEX, RGB, HSL and HSV, each one click to copy. A shades-and-tints palette gives you a whole scale from the one colour, and the WCAG contrast panel tells you — with an AA/AAA grade — whether black or white text will be legible on it.

It accepts #hex, rgb() and hsl() input interchangeably, and every calculation runs in your browser. For building gradients from your colours, see the Gradient Generator; to sample a colour from an image, the Color Picker.

Frequently asked questions

Which formats can I paste?

Any of #rgb, #rrggbb, rgb(…)/rgba(…) or hsl(…)/hsla(…). The tool parses it and shows every other format instantly.

What is the contrast check for?

It computes the WCAG contrast ratio of your colour against black and white text and grades it AA/AAA — the quick way to know if text will be readable on that colour.

Is anything uploaded?

No — all colour maths runs in your browser.

Your files never leave your device

Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.

  • No upload, ever. Turn off Wi-Fi after the page loads and every tool keeps working.
  • No limits. No file-size cap, no queue, no watermark, no account.
  • Runs on your CPU. Batches use several cores in parallel; nothing is throttled.
