BMP vs. PNG | Why Convert BMP to PNG

  • For the same image or information, PNG files are smaller in size than BMP files. BMP files have large file sizes due of the way they manage individual pixels. PNG images automatically compress, allowing them to be smaller than BMP images while retaining the majority of their properties.
  • PNG files are ideal for storing high-quality images that have been compressed. They can also store more detailed graphics than other types of images. As a result, most people now prefer PNG over older formats like Bitmap (BMP).
  • Another advantage of PNG files over BMPs is that after compression and decompression, a picture can be restored to its original quality. PNG enables for further compression to reduce file size even further.

These are few superiorities of PNG over BMP files. Let’s now look at the possible ways to convert BMP image to PNG.
