   Jul 22, 2024 · This image file size calculator will help you estimate the file size of an uncompressed raster image file, provided that you know the image's resolution and its bit depth. In this calculator, you'll learn what an image file is, what bit depth means, and the difference between a raster image and a vector image.

   Feb 8, 2012 · As part of a web app, once images have been downloaded and rendered on a web page, I need to determine an image's file size (kb) and resolution within the browser context (so I could, for example, display that info on the page. This needs to be done client-side, obviously.

   Jan 31, 2023 · Raster images can be thought of as a set of pixel-by-pixel instructions for rendering a two-dimensional grid. Common raster image formats include GIF (.gif), JPEG (.jpg), PNG (.png), and WebP (.webp). The way each image format compresses and encodes these instructions differs, resulting in a huge variance between file sizes: a photographic ...

   Nov 29, 2023 · When you scale down a large image it has more information to work with and so it can appear better when scaled down. If, for example, you use JPEG compression to make a very small image it will tend to be quite blocky and have speckles. Reducing the size of the image will reduce the block size, and average out the speckels.

   Banner/Feature images: These should have a resolution of 150 DPI or higher, but they should also be compressed to reduce file size. Logos: Logos should be created as vector graphics and should have a resolution of 300 DPI or higher, so that they can be used in printed materials as well as on the web.

   Replacing raster images with vector. There are 2 primary image types to consider: Raster and Vector. Raster images, like photographs, are represented as a grid made up of numerous individual pixels that make up an image. The more pixels the image has, the higher resolution/quality/file size it is. Common raster formats on the web are JPEG, PNG ...

   How do you determine a raster image file size?

   • 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. To determine the file size of a raster image file, we have to multiply these variables together.

   What is a raster image?

   • Raster graphics, also known as bitmaps, store image data as fixed pixels. These pixels, which each represent a single color, are fitted onto a grid (or a “raster” proper, which is where the name comes from). Take a step back, and all those colored pixels form a clear image, just like a mosaic.

   What are the different types of raster images?

   • Common raster formats on the web are JPEG, PNG, and GIF. Vector images, like logos, are composed by having the renderer follow algorithms that define lines, curves, shapes, and colours to generate the image. Because there are no pixels to work with, vector images are much smaller in file size compared to their raster counterparts.

   Why are vector images smaller than raster images?

   • Because there are no pixels to work with, vector images are much smaller in file size compared to their raster counterparts. They can also be scaled to whatever size is needed without sacrificing quality due to their algorithmic nature. The common vector format on the web is SVG. Vector graphics can scale to any size without losing quality.

   How many bits are in a raster image?

   • 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. And the more pixels an image has, the more data it stores and the larger its file size. We can determine the number of bits per pixel with what we call "bit depth."

   What is a standard raster image resolution?

   • Standard resolution for a laptop or desktop screen is 72 DPI or 92 DPI. In web design, a raster image is a digital image made up of a grid of pixels (or picture elements), with each pixel assigned a specific colour or shade. These images are resolution dependent so scaling up or down can impact the quality of the images.
