Assuming u have already done with the initial commit, so you know how to add your developed Plugin to wordpress.org repository. Now to add Icon to your wordpress.org Plugins, here is the steps:
Step 1:
Design your very own Plugin Icon image. Remember when design,
Plugin icons are 128 pixels square. HiDPI (retina) icons are supported at 256 pixels square.
Step 2:
Save your Icon Image with file allowed image type, name and size.
Example: icon-128x128.png, icon-256x256.png or icon.svg
Step 3:
Now look at your wordpress.org Plugin svn directories, there are 4 directories by default. One of them is called assets. Put your saved Icon Image/s on the assets folder.
Step 4:
Add this file/s to wordpress.org Plugin repository using your svn client.
Step 5:
Commit the changes to wordpress.org Plugin repository using your svn client.
That’s it. Your changes should be displayed any moments now, if everything is ok.
Allowed image type, name and size:
For wordpress.org Plugins Icon Image, 3 file types are allowed,
svg
png
jpg
If you want to use svg, you will need only 1 file, as svg can be scaled to any size. name your svg icon.svg
if u want to use png or jpg you will need two separate icon files,(for apple retina display) icon-128x128.png(or jpg) and icon-256x256.png(or jpg)
The size of the Icon image to WordPress Plugins should 128x128px and 256x256px, if you are using png or jpg. if you use svg, it could be any size as long as the image is square, my recommendation for svg size is 400x400px.
