How do I transfer minecraft saves from a computer to a laptop?

I have saved a world on minecraft in the browser version on my PC. When i tried to play it in the browser version on my laptop, it doesn't show up. I tried using the %appdata% from the run command, and it won't show up. However, when I saved a world from the desktop version on my laptop, it appeared in the %appdata% folder. How would i get it to do that for the browser version?

 Ansver

if you have hidden files visible, it should be in your C: drive, find the AppData folder, find ".minecraft" and in that folder, there should be a "save" folder or something to that affect, just copy the worlds save file onto a flash drive and place it in the same folder on the other computer
