The sepia() CSS function converts the input image to sepia, giving it a warmer, more yellow/brown appearance. It is used as a value for the filter and backdrop-filter properties.

Try it

filter: sepia(0);

filter: sepia(0.2);

filter: sepia(60%);

filter: sepia(1);

<section id="default-example">
  <img
    class="transition-all"
    id="example-element"
    src="/shared-assets/images/examples/firefox-logo.svg"
    width="200" />
</section>

Syntax

css

/* No sepia conversion */
sepia(0)

/* Complete sepia conversion */
sepia()
sepia(1)
sepia(100%)

/* 60% sepia conversion */
sepia(.6)
sepia(60%)

Parameters

<number> or <percentage> Optional: Specifies the amount of the conversion. A value of 100% applies a complete sepia conversion, while a value of 0% leaves the input unchanged. Values between 0% and 100% are linear multipliers on the effect. Values above 100% are allowed, but the effect is clamped to 100%. Negative values are not allowed. The initial value for interpolation is 0. The default value is 1.

Return value

A <filter-function> value.

Formal syntax

<sepia()> = 
  sepia( [ <number> | <percentage> ]? )

Examples

Using the SVG filter

This example shows three images for comparison: an image with a sepia() filter function applied, an image with the equivalent SVG filter applied, and the original image.

SVG

The SVG <feColorMatrix> filter element can also be used to convert content to sepia. We set the values for the color matrix, then we can reference the SVG effect by the ID of the <filter>:

html

<svg height="0" role="none">
  <filter id="sepia70" color-interpolation-filters="sRGB">
    <feColorMatrix
      type="matrix"
      values="0.5751 0.5383 0.1323 0 0
              0.2443 0.7802 0.1176 0 0
              0.1904 0.3738 0.3917 0 0
              0 0 0 1 0" />
  </filter>
</svg>

The following declarations produce the same effect:

css

filter: sepia(0.7);
filter: sepia(70%);
filter: url("#sepia70"); /* with embedded SVG */
filter: url("fileName.svg#sepia70"); /* external SVG */

CSS

We include CSS that will convert elements to sepia based on their css-filter or svg-filter class:

css

.css-filter {
  filter: sepia(0.7);
}

.svg-filter {
  filter: url("#sepia70");
}
