How can we use the PNG format?

Portable Network Graphics (PNG) belongs to the raster type of image formats where data is structured in a dot matrix or rectangular grid of pixels. The color of pixels has a specific number of bits that is named color depth. Resizing PNG images or any raster format files is undesirable because it causes image distortion.

PNG format uses the DEFLATE algorithm for compression. It can be opened with the majority of web browsers and most image processing apps such as MS Paint, GIMP, Adobe Photoshop, Microsoft Windows Photos, XnView, etc. Its original purpose is to ease up the transfer of pictures on the World Wide Web. Also, PNG files support transparency and a 24-bit RGB color palette.

Advantages and disadvantages of BMP format

BMP or Bitmap is also an uncompressed raster format. The apparent difference between PNG and BMP formats is that BMP files have a much larger file size. A device-independent bitmap (DIB) format file that is BMP you can view on any device capable of the image displaying, even on TV. However, images might be shown differently depending on the device.

Transferring, sharing, or e-mailing this format is difficult because of its size, and that is why you should compress them beforehand. BMP format is not intended for printing and does not have transparency. However, what it has is alpha channels, standard color depths 8-bit and 24-bit, color profiles, etc. Also, BMP format is adapted for 2D images of the real world, landscapes, portraits, etc. 

To open the BMP file, you can use Adobe Photoshop, MS Paint, Microsoft Photo Editor, IrfanView, XnView, Adobe Photoshop Elements, Corel PaintShop Pro, etc.
