CSS filter: make color image with transparency white

Question

I have a colored png image with transparency. I would like to use css filter to make the whole image white but leave the transparency as it is. Is that possible in CSS?

Answer 1

You can use

filter: brightness(0) invert(1);

html {
  background: red;
}
p {
  float: left;
  max-width: 50%;
  text-align: center;
}
img {
  display: block;
  max-width: 100%;
}
.filter {
  -webkit-filter: brightness(0) invert(1);
  filter: brightness(0) invert(1);
}

  Filter:
  

First, brightness(0) makes all image black, except transparent parts, which remain transparent.

Then, invert(1) makes the black parts white.
