BMP vs PNG: what changes
- PNG files are usually much smaller than BMP, so this is a good way to save space or speed up a page.
- Converting to PNG gives you transparency support, though this conversion won’t recover any transparency that BMP already discarded.
- BMP stores pixels with no compression at all, resulting in very large files. Converting to PNG significantly reduces file size.
