BMP vs PNG
BMP · Bitmap
BMP is an old, uncompressed Windows image format. Because there's no compression the files are huge — converting to PNG or JPG keeps the quality while cutting the size dramatically.
PNG · Portable Network Graphics
PNG is a lossless raster format with full alpha transparency. It keeps text and sharp edges crisp, which makes it ideal for logos, icons, screenshots and UI graphics — at the cost of larger files for photographs.
