Do you find it frustrating that when you change the width of your map, it gets all messed up? Too lazy to use Tiled? Well this tool is for you! Just download your messed up map, upload it to the site (make sure you remember the width of your map before you changed it), and voila! Your map has the extra width without being distorted! You can also use this tool to cut off tiles from the side if you changed your map to be narrower than it was before, or add empty rows above the map if you want to expand on the top.
Before:
