Question 1: Can PNG images be compressed?
Answer: Yes, PNG images can be compressed. PNG image files are lossless compressed bitmapped images. Even though the PNG images are compressed, the file size can be very large. So, you can shrink PNG file size with an image compressor.
Question 2: What's a typical file size for PNG before and after compression?
Answer: The file size of PNG is various depending on the type of image data saved. Generally speaking, an image file saved in PNG is larger than saved in JPG. When it comes to the compressed file size, it is determined by the output format and compression level. Briefly, compressing PNG to JPG and higher compression level can produce smaller file size, but the image quality may be damaged.
Question 3: What is PNG file format used for?
Answer: A PNG file contains a bitmap of indexed colors and uses lossless compression. It is similar to a GIF file, but without copyright limitations. In short, PNG files are commonly used to store graphics for web images.
Question 4: What are the advantages of PNG?
Answer: To learn the advantages of PNG, we compare it with other popular image formats. Firstly, PNG was originally created as an improved replacement for GIF. PNG cannot store dynamic visual content, but it is much smaller than GIF. Compared JPG, PNG is larger, but it can store transparency layers. If you want to compress PNG while preserving transparency, you should keep the image format. Compressing PNG to JPG will lose the transparency layer. Plus, JPG has a big compressing ration, which reduce the quality of the image. JPG is the better output format for photographs, while PNG is a better option for images storing text, line art and other graphics.
