Using PNG over JPEG in this situation will result in a bigger file size (often 5-10 times more than JPEG).Williams background in scientific computing and education from Shippensburg and MIT provided the foundation for MarketingCloudFX and other key research and development projects at WebFX.
24 Bit Png Software Programs UsingThen, it was announced that software programs using GIF would require a license (this was because of the Unisys patent for the LZW compression method used in GIF).This change sped up the development for its successor: the PNG format.PNG, which stands for Portable Network Graphics, gained popularity and, nowadays, its probably the most used image format when it comes to web design, alongside JPEG. For example, the TIFF image format is not designed for web use; its used for printing. Examples of image formats for the web are JPEG, PNG, GIF, and SVG. This means that you will not get the exact same image as the original if you try to decompress it. The data loss, in most instances, is done in such a way that you dont lose too much quality; at least not enough that people will notice. ![]() An example of lossless compression is when you are zipping up a document using the ZIP format. When you unzip your document, it will be the same as the original. What this essentially means is that, by saving your original images using JPEG, you might witness some quality loss (the same goes for PNG in certain situations, as youll see later on). If you skipped Design 101, raster images, unlike vector image formats such as SVG, cannot be rescaled without losing quality. However, raster images are better than vector images for complex images such as photographs. The CMYK color model, which is typically for print purposes, is not available when saving images in PNG format. In short: the PNG image format is not optimal for graphics that will be printed. The numbers are shorthand for saying 8-bit PNG or 24-bit PNG. Not to get too much into technicalities because as a web designer, you probably dont care 8-bit PNGs mean that the image is 8 bits per pixel, while 24-bit PNGs mean 24 bits per pixel. This difference is not 100 true because Adobe products Save for Web command allows PNG-8 with alpha transparency. Im not alone on this, Jeff Atwood, founder of StackOverflow and the Coding Horror blog, will agree. Note that for the sample image below, you would not use PNG-24 because it has simple colors and will also weigh more than GIF. However, the PNG over GIF notion still stands: If you save a photographic image (such as a photo of your mom and dad), PNG-24 will have a better result than GIF. ![]() This is because it uses a lossy compression algorithm specifically designed for photographic, rich-color images.
