LCH to HEX

A free LCH to HEX converter: type lightness, chroma and hue, such as 65 40 30, and get the hex code #DE847C. Handy when you have tuned a color in LCH, or found an lch() value in a stylesheet, and need a hex code for a design tool, an email template or older software. Colors outside sRGB get the nearest hex code and a note.

How to convert LCH to HEX

  1. 1Type L, C and H into "Color", for example 65 40 30
  2. 2Or paste lch() straight from your CSS
  3. 3Copy the hex code from the big line
  4. A six digit hex code that matches your LCH color

How it works

  • Hue in any CSS unit.Degrees are the default, and deg, rad, grad and turn are read as well
  • Too vivid is handled.When chroma is beyond sRGB, the tool lowers it and keeps lightness and hue
  • Nothing is sent anywhere.The numbers are worked out in your browser

What you can do

  • Turn LCH into a hex code, from three bare numbers or a full lch() value
  • Write chroma as a percentage the CSS way, where 100% stands for 150
  • See the RGB, HSL and CMYK of the same color, each with a copy button
  • Check how close the nearest CSS color name and Tailwind color are, shown as ΔE (CIEDE2000)

Good to know

  • LCH can reach far beyond sRGB. lch(60% 120 250), for example, becomes #00A2C6, the nearest color HEX can hold, and a note tells you the color was moved
  • The tool reads CIE LCH with the D50 white, as CSS lch() does. An OKLCH value typed here as bare numbers gives a very different color, so write oklch() around it
  • L runs from 0 to 100. A negative chroma is read as 0, which is a gray

Questions

How do I convert LCH to hex?

Type the three LCH numbers or paste lch() into the field. The hex code shows up in the big line right away. lch(65% 40 30), for example, gives #DE847C.

What do I type for the hue?

An angle from 0 to 360: around 40 is red, 90 yellow, 140 green and 290 blue. A unit such as 0.5turn works too.

Why does my LCH color look duller as hex?

Your chroma is higher than sRGB allows for that lightness and hue. HEX can only show colors inside sRGB, so the tool takes the nearest one with less chroma and says so in a note.

Does the converter send my color anywhere?

No. It runs in your browser, and no request is made with your color.

How it works

From “ugh, this file” to done, in three steps.

  1. Drop it, or pick a task

    No file? Search for what you need. Files are processed on your device, not uploaded for processing.

  2. Pick what you want

    Smaller, another format, signed, merged. One click, no settings to study first.

  3. Make it a recipe

    Need three steps in a row every week? Chain them once and run the same recipe next time.

For companies

One approved toolbox for the whole team.

In offices, on building sites and in agencies, teams handle sensitive files all day. ToolRecipe gives everyone the same tools and the same recipes, and the files are processed on each person's own computer.

  • Files are processed on the employee's device
  • Company recipes everyone runs the same way
  • One place instead of ten converter sites

How it works

Small tools that run in your browser.

What runs where

Your browser keeps the tools you use: the same kind of tools you would otherwise use on a website. Your files stay on your device and are not uploaded.

A tool your browser has kept also works without internet. Under Offline, at the bottom of this page, you can save everything at once, and the site keeps working without a connection.

Some tools have AI built in, for example to remove a background or enlarge a photo. Your browser downloads their AI models once, from ToolRecipe itself, and then runs them on your device. No tool sends your files to an online AI service or to us.

On a computer, these tools use the graphics chip when it passes a short check, because that is usually faster. On a phone they run on the processor, with settings that fit in a phone’s memory.

Using a tool

Give the tool your file, choose what you want, save the result.

  • Start on the home page

    Drop a file in the box on the home page, or try a sample photo. Pick what you want to do and press “Open tool”. The tool opens with your file in it.

  • Put a file in

    Drop it anywhere on the page, pick it with “Choose a file” or paste it. No file yet? Search for the job, like “heic to jpg”.

  • Choose the settings

    Each tool shows only the settings it needs. Often one click is enough.

  • Save the result

    Saved files go to your downloads. A copy also waits in Results.

  • Results

    The Results tab on the right edge keeps your latest results in this browser until you remove them. “Clear all” empties it.

Chaining tools

What one tool makes can go straight into the next, without saving it and opening it again.

  • “Use it in”

    Tap a result in Results and pick a tool under “Use it in”. The result is handed on to that tool.

  • Drag it

    You can also drag a result onto an open tool. On a phone, touch and hold it first.

  • From a chain to a recipe

    To run the same tools again later, make a recipe of them in the recipe builder.

The recipe builder

Drop a file in the box on the home page and add the steps one at a time. Nothing runs until you press “Run recipe” or “Open tool”.

  • Pick what to do

    The box shows a tile for each kind of job your file allows, such as “Make it smaller”. A tile opens its ready-made choices and every tool of that kind. “Back” returns to the tiles.

  • Add steps

    Each choice becomes a numbered step in the row at the top. “Add another step” shows suggested next steps, then the tiles for what the last step makes. The cross on a step removes it, and “Undo” brings it back.

  • Name it

    The recipe is called “My recipe” until you name it. Press the pen next to the name to change it.

  • Run it

    With one step, press “Open tool” and the tool opens with your file. With two or more steps, press “Run recipe”. The recipe opens on its own screen, and the steps run one after the other.

  • Steps that need you

    Most steps run by themselves. A step marked “Your turn” waits for you, for example when you need to sign a PDF. When you are done, press “Continue to next step”, or “See the result” on the last step.

  • Save or start over

    “Save the current steps as a recipe” keeps the steps under My recipes. You do not have to run them first. On the recipe screen, “Save this recipe” under the steps does the same. “Start over” clears the box for another file.

Recipes

A recipe is a few tools in a row: what one step makes goes into the next.

  • Ready-made recipes

    “All recipes” in the menu lists recipes for common jobs. Drop your file on one and it runs step by step.

  • Make your own

    Build one in the box on the home page. On My recipes, “New recipe” opens the same builder at the top of the page, with a search box for the tool you need next.

  • My recipes

    Your saved recipes are under “My recipes” in the menu, in this browser. Open one to rename it or change its steps. Changes are saved at once. “Start with a file” runs it on a new file. “Delete” asks you to confirm, then deletes it.

  • Share a recipe

    “Copy share link” makes a link to the steps, never to your files. Nothing starts for the person who opens it until they choose a file of their own.

Ways of working

Tools and recipes run in your browser, on your device.

  • Start from a file

    Drop it in the box on the home page and pick what you want to do. Choose one step to open its tool, or add more to make a recipe.

  • Start from a tool

    Search for the job or open a tool from the menu. When the result is ready, tap it in Results and pick the next tool under “Use it in”.

  • Keep the steps

    A saved recipe keeps its name, its tools in order and the setting of each step. It never keeps your files or their names.

  • Come back later

    Open My recipes in the same browser, on the same device, and run a recipe on a new file. A recipe stays there until you delete it or clear your browser data.

Finding tools again

Every tool and every recipe has its own address.

  • Bookmark it

    On a tool’s page, press Ctrl+D (⌘D on a Mac) to keep it in your browser’s bookmarks.

  • On your home screen

    A tool can sit on your phone’s home screen like an app. See Install, below, for how.

  • Your own recipes

    Recipes you saved are under “My recipes” in the menu.

  • The stars

    The stars under a new result ask how well the tool worked. Your answer helps us improve it. Stars do not save the tool for you.

How you can check that files stay here

Tools read your files and make the result in this browser, on your device. Your files are not uploaded to be processed.

A security policy lets this page contact one address only: our own server, for counts. It passes page views and a fixed list of actions on to an analytics service in the EU, which counts them for us. Neither gets your files or their names. Anything else is blocked, and the badge at the top turns red and counts it.

If a tool fails, the page counts that too: only the kind of error and where in our code it happened, never the error's text, your files or what you typed.

If you send us your email address to ask about ToolRecipe for companies, we store it with that request at our analytics service in the EU and receive it by mail, to answer you. Write to info@toolrecipe.com to have it deleted.
