Creating Icons for Windows 10

[alsearsa]

Using PSPX3 on Windows 10.

Attempting to create icons for start page, etc. I want the completed icon tile to be full of my art. What I am getting is a tile full of a background color and a small version of my art in the center. I know this is possible as I am looking at examples for Firefox, Thunderbird, etc, etc. I have tried several conversion apps (local and online) to convert .png to .ico. I have tried creating the .png at both 256 px and 32px. I have used both my art and art grabbed from 'net. I'm missing something.

What I want is something like this

I'm getting something like this

Being 82 likely doesn't help. But I'm stuck with that.

Help appreciated.

There are some fine free Icons editors to speed up work:

Thanks Radim. I will peruse those editors. Still would appreciate info related to creating the art within PSPX3.

I tried a couple of the suggestioned editors (trial versions) with same result. I still get a small icon centered in a larger tile. Size of the creation canvas doesn't matter. I made one 2560 x 2560 just to be extreme. Interestingly, I have actually done this successfully once but have no idea what I did correctly.
