This is my Pokemon Generation I graphics compressor. It works the same way as Sawakita's. Upload a Game Boy 2bpp binary file, and it compresses it and lets you download it. Width/height are in tiles. If you specify an offset (in decimal, or prefix with 0x for hexadecimal), you can download it as an IPS patch (note that it doesn't care what offset you choose, so if the image you select compresses to larger than the one already there, it will overwrite the next one and break things).
