im the pixels anon and yes please!!!
ok so when you go to emojibank.com and like type in your query in the top (i usually just google translate what im looking for to japanese) you should see this and when you click on your pixel itll pop up in the little box at the bottom (its called a pocket)
next what you will want to do is go here and right click on the pixel you want. then click on inspect
you should see something like this on your screen; the blue highlighted part corresponds to the gif you selected.
now what you want to do is copy this url (you can double click on it, which will allow you to select text), and then go to emojibank.com/(url you copied) , and download the image file that gives you. make sure there isnt a double slash like emojibank.com//(url) and only one slash there.
this will make a lot more sense if you have basic knowledge of html/css/the inspect tool but good luck anyways! i hope this helped and lmk if i need to clear anything else up
