Is the color converter free?

Yes. Converting colors on In1 is completely free with no account and no limits.

Which formats can I convert between?

HEX, RGB and HSL, in any direction. Enter any one and you instantly get the other two.

Is my input uploaded anywhere?

No. All conversion happens locally in your browser, so nothing you type leaves your device.

What input formats are accepted?

HEX (#rgb or #rrggbb), rgb(r, g, b) and hsl(h, s%, l%). You can also pick a color with the picker.

What's the difference between RGB and HSL?

RGB lists red, green and blue channels (0–255), matching how screens work. HSL uses hue, saturation and lightness, which is more intuitive for making a color lighter, darker or more muted.

Does it support transparency (alpha)?

This tool focuses on solid colors in HEX, RGB and HSL. For most design and CSS work those three cover what you need.

Convert colors between HEX, RGB and HSL

Type a color in any common format — HEX, RGB or HSL — or pick one visually, and instantly get all three values with a live preview. Copy whichever format you need. Everything runs in your browser.

How to use Color Converter

1
Enter a color
Type a HEX, RGB or HSL value, or use the color picker to choose one visually.
2
See all formats
The HEX, RGB and HSL equivalents appear instantly, with a live preview swatch.
3
Check the preview
Confirm the color looks right in the swatch before you use it.
4
Copy what you need
Copy any of the three formats with one click and paste it into your code or design.

One color, every format you need

Colors on the web are written in several different notations, and the one you have is rarely the one a particular tool wants. A designer hands you a HEX code, but your CSS variable is defined in HSL. A screenshot gives you RGB values, but the design system uses hex. Converting by hand means looking up conversion math or juggling another app. In1's color converter removes that friction: enter a color in HEX, RGB or HSL and it instantly shows you all three equivalents at once, each ready to copy with a single click. There is no calculation to do and no formula to remember. You can also pick a color visually with the built-in color picker and read off its values, or paste a value and see exactly what it looks like. Whether you are translating a brand color into the format your code expects or just checking what a hex string actually is, every representation is right there in front of you.

See the color, not just the numbers

Color codes are abstract — '#3a7bd5' tells you very little until you actually see it. That is why the converter shows a live swatch of your color alongside the values, updating the moment you change the input. Seeing the real color matters: it lets you confirm you pasted the right code, compare a value against a design, or simply sanity-check that the color is what you expected before you drop it into a stylesheet or a document. The preview also makes the picker genuinely useful — nudge the color visually until it looks right, then copy the exact HEX, RGB or HSL value it produces. This tight loop between the numbers and the visual is what turns a dry conversion utility into something you actually enjoy using, because you are always working with the color itself, not just a string of characters that could be anything.

Understand HEX, RGB and HSL

Each format describes the same color in a different way, and each is good at something. HEX (like #3a7bd5) is the compact six-digit code most common in design tools and CSS; it is really just RGB written in hexadecimal. RGB (like rgb(58, 123, 213)) lists the red, green and blue channels from 0 to 255, which maps directly to how screens emit light and is easy to tweak channel by channel. HSL (like hsl(214, 64%, 53%)) describes the color as hue, saturation and lightness, which is far more intuitive for humans: you can make a color lighter, more muted or shift its hue just by changing one number, without guessing at red-green-blue combinations. Being able to move between all three means you can work in whichever model fits the task — HEX to paste into a design file, RGB to fine-tune a channel, or HSL to create a lighter or darker variant of the same hue.

Private and instant — nothing is uploaded

Color conversion is pure math, so there is no reason for it to involve a server — and In1 does it all locally in your browser. Nothing you type is uploaded, stored or logged, and there is no account to create. The conversions happen the instant you type, with no network round trip, so the values and the preview update in real time as you adjust the input or drag the picker. This local-only approach also means the tool works offline and stays fast no matter how many colors you convert. For most people privacy is not the main concern with a color, but the same architecture that keeps your data on your device is what makes the experience immediate and reliable: there is never a spinner, a queue or a failed request between you and the answer. You paste or pick a color and the results are simply there.

Who uses a color converter?

The audience is wide. Front-end developers convert HEX codes from a design into the RGB or HSL values their CSS, Tailwind config or theme variables expect, and back again. Designers translate colors between the formats their various tools prefer, or grab the exact code for a color they picked by eye. Digital artists and illustrators read off values to reproduce a color precisely across apps. Marketers and brand managers confirm that a brand color is being used consistently by checking its codes. Students learning web development use it to understand how the three color models relate to one another. Even hobbyists building a website, theming an app or tweaking a chart reach for it to nail down a color. In every case the goal is the same: take a color in whatever format you have, see it, and get the exact value you need in the format you want — instantly, privately and for free. It also pairs well with picking palettes by hand: drop in a base color, switch to HSL, and nudge the lightness up or down to build a consistent set of tints and shades from a single starting point.
