<feMerge>

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

See full compatibility

The <feMerge> SVG element allows filter effects to be applied concurrently instead of sequentially. This is achieved by other filters storing their output via the result attribute and then accessing it in a <feMergeNode> child.

Like other filter primitives, it handles color components in the linearRGB color space by default. You can use color-interpolation-filters to use sRGB instead.

Usage context

Categories	Filter primitive element
Permitted content	Any number of the following elements, in any order: `<feMergeNode>`

Attributes

Filter primitive attributes: x, y, width, height, result

DOM Interface

This element implements the SVGFEMergeElement interface.
