![]() ![]() Image as a background in CSS: using this, images can be added within a div without adding additional HTML attributes to the page. This way is the most popular one and also provides aįallback in case the image cannot be displayed. Image as an attribute: a simple way of adding an image to a web page. Images can be uploaded via many various ways through the use of HTML and CSS. Generally, the more the file size is reduced, the lower the image quality. GIFs also support transparent backgrounds, just like PNGs do. JPEGs, on the other hand, handle complex colors very well. PNG images are the best option for graphic design due to supporting transparent backgrounds. The most common file formats for raster-type images are:Īll of the mentioned formats have their quirks and features. They are mostly used for photography and printing. File sizes of raster images are largely dependent on their exported resolutionĪnd are, in most cases, large themselves. Limits the size of the image that can scale up without seeing individual pixels. Conversely, having fewer pixels yields a lower-resolution image. The more pixels there are within a raster image, the bigger the image's file size. Said to have a higher resolution, resulting in better image quality. When a raster image has more pixels, it is Them has a fixed number of pixels that determines the quality of the image. These images are created by digital cameras or scanners that output digital files onto the computer. Pixels appear as small dots or squares whenĮnlarging or zooming into raster-type images. Primary use of such images is creating photographs that will inevitably become pixelated as you scale them. On the other hand, these images are made out of a collection of pixels (the smallest unit of visual measurement) - making them resolution-dependent. The most popular file formats for vector images are EPS (Encapsulated PostScript), SVG, and AI (Adobe Illustrator Artwork). Vector images are mostly used for fonts, logos, some digital Finally, their file sizes are small since they consist of points and lines. Another point to take they're also device independent – their quality does not depend on the number of Lines are sharp without losing quality or detail. What is unique about SVGs is that they're not pixel-based and are resolution-independent – making them infinitely scalable. Those consist of anchored points that are connected by lines and curves. Vector images belong to vector graphics, also known as Knowing that, stretching and expanding a vector image will retain a smooth pixel-free appearance. They are more like digital art rendered by the computer using a mathematicalįormula. ![]() The key to their appearance is points and lines, which make them appear smoother. The two primary formats are raster and vector images, but there are also some new incoming formats. Choosing the right format ultimately yields a much greater user experience without Static images, or simply those that don't move, come in various formats. The term "images" variesĪlong the board, and it includes many different types of visual representations, such as: ![]() It's a common misconception that people use the term "images" to note exclusively photographic material, but that's not the case. It can reference images from HTML, CSS, JavaScript, or any Parcel has built-in support for resizing, converting, and optimizing images. ImageMinimizerWebpackPlugin, which community members maintain. The automatic image optimization is done with the help of various bundlers, such as webpack and parcel. Various online image compressors that deliver high-quality compressed files. But remember that you must balance the image size and resolution.Īs for image optimization, it is possible in two ways - manual and automatic. In case you can't compress your images, you can resize them. Finally, it would help if you considered compressing images to prevent overload and improve the experience of using the ![]() The compression method makes images smaller by reducing the This method reduces application requests and the page's download size. With the caching method, images are stored in the browser's cache or proxy server so that theyĬan be accessed easily. So to improve the performance and optimization of images, web developers mostly use these three methods: caching,Ĭompressing, and resizing. To effectively having more content within themselves. Higher-resolution images take up more storage due Page down causes stutters and, in turn, negatively affects the end-user experience. For that reason alone, optimization is the top priority. The more you have, the harder they are to handle. ![]()
