What is the compression of PNG?
An acronym for Portable Network Graphics, PNG is a lossless file format designed as a more open alternative to Graphics Interchange Format (GIF). Unlike JPEG, which relies on DCT compression, PNG uses LZW compression, which is the same as GIF and TIFF formats.
How do I reduce the size of a PNG file?
Reduce PNG file size by limiting colors One of the most basic ways to cut down on a PNG’s file size is to limit the number of colors that the image has. PNGs can be saved as Grayscale, Truecolor, Indexed-color, Grayscale with alpha, and Truecolor with alpha.
What is a PNG file not suitable for?
The disadvantages of the PNG format include: Bigger file size — compresses digital images at a larger file size. Not ideal for professional-quality print graphics — doesn’t support non-RGB color spaces such as CMYK (cyan, magenta, yellow and black).
Why is my PNG file so large?
PNG files are lossless compressed bitmapped images. While they are compressed, they can still attain large file sizes depending on the type of image data saved—they are best suited for images with large areas of solid colours and defined boundaries (such as logos).

What is the PNG compression algorithm?
PNG was created to both improve upon and replace the GIF format with an image file format that does not require a patent license to use. It uses the DEFLATE compression algorithm, that uses a combination of the LZ77 algorithm and Huffman coding.
Is a PNG file smaller than a JPG file?
PNG is a lossless compressed format, which makes it good for both photographs and text documents. A PNG will generally be larger than a JPEG, and sometimes smaller than a TIFF. Interestingly, it was originally developed to replace the GIF, but the formats are drastically different, and both have a place in today’s computer environments. Jul 16 2019
