Bulk Color Converter

Paste any list of HEX, RGB, HSL, HSV, or CMYK values and convert the whole batch to a new format in one click.

Paste your color values — one per line or comma-separated — choose a target format, and click Convert to transform the entire list at once.

Input Colors

One color per line. Supports HEX, rgb(), hsl(), cmyk(), and CSS names.

Batch convert entire color lists with one click

The bulk color converter takes a list of color values in any common format — HEX, RGB, HSL, HSV, or CMYK — and converts the whole batch to a single target format in one pass. Instead of pasting colors into a single-color tool one at a time, you drop in your full palette, design token export, or stylesheet snippet and get a clean, copy-ready list back.

Input parsing is forgiving: it accepts one color per line, comma-separated values, mixed casing, and HEX codes with or without the leading #. That makes it ideal for cleaning up messy palettes pulled from Figma, a CSS file, or a spreadsheet before you hand them off to another stage of your workflow.

When a bulk color converter saves real time

  • Design system migrations. Convert dozens of legacy HEX values to HSL or OKLCH in one shot when modernizing a stylesheet.
  • Print handoff. Turn a screen palette of HEX/RGB values into CMYK for your print vendor without recalculating each swatch.
  • Design tokens. Normalize a mixed list of color formats into one canonical representation before exporting variables.
  • Palette cleanup. Standardize colors scraped from multiple sources into a single, consistent format.

Supported color formats

The batch color converter recognizes the major CSS Color formats used in web and print:

  1. #RRGGBB and shorthand #RGB HEX
  2. rgb(r, g, b) with 0–255 channels
  3. hsl(h, s%, l%) with hue in degrees
  4. hsv(h, s%, v%) for picker-style values
  5. cmyk(c%, m%, y%, k%) for print workflows

Tips for clean batch conversions

For best results, paste one color per line and avoid extra punctuation around the values. If you only need to convert a single value, the standalone Color Converter gives a richer per-color breakdown. To go from a screen palette to print, the RGB to CMYK Converter includes gamut warnings, and after conversion you can ship the results into a design token exporter to generate CSS variables, SCSS, or a Tailwind theme config. If you want to audit how your converted palette pairs together, drop it into the palette contrast grid to spot accessibility issues before shipping.

All conversions run in your browser, so your color lists never leave your machine — useful for unreleased brand palettes and client work.
