This tutorial focuses on resizing, specifically, but similar techniques can be used to crop or apply filters to images. For our purposes, we'll use an invisible canvas element as an image manipulation tool. The element is typically used for games and other visual apps to draw things that cannot be represented by standard HTML elements. Resizing images with vanilla JS and by Gregory Schier ( CodePen. Luckily there's an easy way to do it using the element and a few lines of JavaScript. Photos should be resized on the client before uploading, especially now that smartphones are available that can capture 100MP photos. We can do the following steps to resize an image. Large photos cost the user money in bandwidth □.While the results of this are mixed so far, AI is advancing at such a rapid pace, it may not be long before even low-quality images can be blown up to massive resolutions.Allowing users to upload photos directly to a website, without first resizing them, hurts the user experience for two reasons. Some image editing software, Photoshop included, has begun using AI-based image enlargement technologies to help keep images sharp, even when they're being made much larger than their original size. This is an area where AI is being employed. There are some exceptions with ultra-high-resolution pics with ppi counts above 300, but those are far less common than your average 72-ppi images featured on most websites. Without getting too deep into the technical details of ppi (pixels per inch) resolution, suffice it to say that most images will look significantly worse once their size has been doubled, and will probably be downright unusable if you go past that. This is why enlarged images often look "pixelated," because each of the individual pixels in our above example is now about four times as large. Those pixels are generated by turning each one of the original image's individual pixels into multiple pixels. That means the software has to create 4.32 million new pixels to fill out the new image. if you enlarge that image to 3,200 x 1,800, you're creating a new image with 5.76 million pixels. For example, a 1,600 x 900 image has 1.44 million pixels in it. There are only a certain number of pixels in a given image. Unfortunately, the answer to this question is usually no. Can I make my image look better by enlarging it? This means that for an 8 x 10 frame, you'd want an aspect ratio of 8:10 likewise 16 x 9 would be 16:9, and so on. Lastly, if you're planning to print your photo, you'll want to use the aspect ratio of your framing size. Check the support page of the social network you want to share the image on for more info. Instagram's classic square photos use a 1:1 ratio, but it, and other sites, also support ratios likes 4:5 for portraits, 2:1 for landscapes, and so on. If you're sharing the image via social media, the best aspect ratio can vary by site. Meanwhile, most desktops and laptops also use 16:9, but some "ultrawide" monitors stretch out that width to 21:9. For example, most smartphones use a 9:16 aspect ration (900 x 1,600 or 1,800 x 3,200, for example). If it's going to be a wallpaper, you'll want to use the aspect ratio of the display it will live on. Micro-social media: What is it and which tools should you try?
