Convert image to 128x1284/15/2024 ![]() ![]() For example, a 1-bit image can only show black or white pixels as 1 bit can only store two values, a 1 or a 0 (2 1 = 2 values or colors). The number of colors in a certain bit depth follows the binary system and is equal to 2 raised to the bit depth value. We can determine the number of bits per pixel with what we call "bit depth." What bit depth indicates is the number of colors that we can show in the image file. And the more pixels an image has, the more data it stores and the larger its file size. Each pixel in a raster image typically takes up about 1 to 8 bits for black-and-white images and 8 to 64 bits for colored images. ![]() To determine the file size of a raster image file, we have to multiply these variables together. Two parameters define a raster image's file size, and these are the number of pixels in the image and the bit depth of each pixel. However, you can even approximate a compressed image file size using this calculator if you know the image file's resulting bit depth. It's also worth noting that this image file size calculator only determines the file sizes of uncompressed images. Vector image attributes can vary an incredible amount, just like how you can express a mathematical graph with a variety of different mathematical equations. However, this image file size calculator can only determine the file sizes of raster images. These "graphs" also refresh every time we scale or zoom a vector image, making us always see smooth lines and curves with consistent colors and details. Displaying a vector image is like graphing these equations on a cartesian plane every time we open the image file. You can think of it as a list of mathematical equations that we can graph on a cartesian plane. Unlike raster images that store data for each pixel in an image, vector images store data as a compilation of these equations representing each of the said attributes. On the other hand, vector images consist of attributes like curves, paths, shapes, line or stroke thicknesses, colors, etc., that are stored in formulas or equations. (You might wanna take a look at our ppi calculator.) A raster image with a high pixel count, or resolution, lets us zoom in on the picture up a significant amount before we start to see the individual pixels that comprise it. One interesting feature of PNG files is the ability to create transparency in the image, particularly a transparent background.Pictures with more pixels tend to show more details and more quality, especially when trying to zoom in on that image. PNG files are a bit larger than other file types, so exercise caution when adding them to a web page. If you are having trouble opening PNG files, use our PNG to JPG, PNG to WebP, or PNG to BMP converters.Īlternative programs such as GIMP or Adobe Photoshop are useful for opening and editing PNG files. ![]() PNG files are also easily viewable on all web browsers. Generally, PNG files will open in your operating system’s default image viewer. The benefits of using PNG are Plus, PNG is an open format that uses lossless compression. PNG also supports animations with better transparency (try our GIF to APNG). ![]() PNG images can have RGB or RGBA colors and support transparency, which makes them perfect for use in icons, or graphic designs. Portable Network Graphics (PNG) is a raster-based file type that compresses images for portability. ![]()
