One of the main differences between raster and vector files is their resolution. The resolution of a raster file is referred to in DPI (dots per inch) or PPI (pixels per inch). If you zoom in or expand the size of a raster image, you start to see the individual pixels. Raster files display a wider array of colors, permit greater color editing ...

The raster file format, along with vector, is one of the main two file types used for digital images. One of the strengths of raster files is the ability to capture detailed graphics and high-quality photographs taken from digital cameras. Explore the key features of raster images, their most common uses, and how they differ from vector images.

It can be veryconfusing. Understanding some of the details about how photographs are stored on disk, how they are displayed, and how they are printed can allow you to make a dramatic difference in the size of documents, webpages, emails, and more. It isn’t terribly complicated to understand, but the details can be a little confusing if you don’t kn...
A pixel (short for “picture element”) is a dot. Seriously, that’s all it is. One dot. We can do things with that dot, like give it a color, and I’ll get to that in a moment, but at its most fundamental level, a pixel is nothing more than a single dot. That was easy.
Computer display devices, like the screen on which you’re reading this, is nothing but a rectangle of pixels. The rectangle is so many pixels wide (horizontally) and so many pixels high (vertically). For example, one screen I use is a rectangle that is 1,920 pixels wide and 1,200 pixels high, or simply “1920 × 1200”. That’s referred to as the resol...
With pixels and resolution under our belt, we can start talking about size. Image size can be a confusing concept because there are two different kinds of size we’re talking about: 1. The physical size of the image displayed on screen or printed on paper. We measure that in inches or pixels. 2. The size of the file— like “.jpg” or “.png” files — in...
We can’t really talk about the size of an image in bytes without first discussing how color is represented in an image.
The magic acronym when displaying pictures is DPI, or Dots Per Inch. Remember, pixels are dots, so when we talk about DPI, we’re really talking about how tightly packed the pixels are when they’re displayed (or “rendered”) on an output device.2 For example, many LCD displays present around 75 pixels (or dots) per inch. It varies widely, depending o...
The images above were taken as a full-color photo taken on my 12-megapixel camera. If displayed at 100% resolution (meaning each pixel in the image is displayed on a single pixel on the monitor), that 4,288 by 2,848 pixel photo would require a 75 DPI monitor nearly five feet wide by a little over three feet high to display completely. If printed at...
Make your pictures smaller. Think about how your image is going to be used, and resize the image for that target use. Make it as big as necessary for that use, but no bigger. Is it simply going to be viewed on a screen, or will it get printed? Understand the typical DPI that would be used for each so you can pick an appropriate size in pixels. Want...
As I said at the beginning, all of this can be confusing, and your head might be spinning by now. I get it. My advice to you is to pick an image and play with it. Specifically: 1. Make a copy of your original image as it came from your camera or wherever else. This is important, because no matter what you do next, you’ll always have the image back ...
Dec 8, 2023 · Raster images are made up of pixels. They are an optimal format for photographs, larger file sizes, and are more accessible and shareable. Vector images are formed by curves and paths dictated by mathematical formulas. They have smaller file sizes and are an ideal format for things like logos, geometric shapes, and type.
Oct 2, 2024 · Snagit is a screen capture and image editing software that supports a wide variety of image file formats. See a complete list of supported file formats. Snagit is capable of converting one file format to another, such as converting a PNG to JPEG with minimal quality loss. You can also add annotations, adjust image size, and enhance the visuals ...
Oct 10, 2024 · These are the types of images that are produced when scanning or photographing an object. Raster images are compiled using pixels, or tiny dots, containing unique color and tonal information that come together to create the image. Since raster images are pixel based, they are resolution dependent. The number of pixels that make up an image as ...

Oct 25, 2019 · Vector and raster images differ in their resolution, the amount of detail they contain, and where they are used. It’s important to understand the fine differences between them and when to work with each—no matter if you’re a new designer, a seasoned pro or a marketer looking to hire a designer. Both raster and vector images have their own ...
