One of the simplest ways to resize an image in the HTML is using the height and width attributes on the img tag. These values specify the height and width of the image element. The values are set in px i. CSS pixels. The exact algorithm used by the browser for scaling can vary and depends on the underlying hardware and OS.

When you specify both height and width , the image might lose its aspect ratio. You can preserve the aspect ratio by specifying only width and setting height to auto using CSS property. This will render a px wide image. The height is adjusted accordingly to preserve the aspect ratio of the original image.

You can also specify the height attribute and set width as auto , but most layouts are generally width constrained and not height. You can specify the width in percentage instead of an absolute number to make it responsive.

It might result in a blurred image as the image can be scaled up to be larger than its original size. So far, we have discussed how to resize an image by specifying height or width or both of them. When you specify both height and width , the image is forced to fit the requested dimension. It could change the original aspect ratio. At times, you want to preserve the aspect ratio while the image covers the whole area even if some part of the image is cropped.

To achieve this, you can use:. You can control the resizing and cropping of the image using the following CSS attributes-. You can override this by setting the height and width using the background-size CSS property. You can scale the image upward or downward as you wish.

The longest of either the height or width will fit in the given dimensions, regardless of the size of the containing box. Before this CSS property was introduced, we had to resort to using a background image. Along with inherit , initial , and unset , there are 5 more possible values for object-fit:.

You can use object-position to control the starting position of the image in case a cropped part of the image is being rendered. The original aspect ratio of the image is same, but the image is resized so that it is fully visible. We have added 1px border around the image to showcase this. The original aspect ratio is preserved but to cover the whole area image is clipped from the left and right side.

Image is forced to fit into a px wide container with height px, the original aspect ratio is not preserved. Since the full-sized image is loaded anyway before resizing happens in the browser, it takes more time to finish downloading and finally rendering. This means that if you have a large, 1. With ImageKit. For example -. The exact scaling algorithm used by the browser can vary, and its performance depends upon underlying hardware and OS. When a relatively bigger image is resized to fit a smaller container, the final image could be noticeably blurry.

There is a tradeoff between speed and quality. The final choice depends upon the browser. Firefox 3. But this could vary. You can use the image-rendering CSS property, which defines how the browser should render an image if it is scaled up or down from its original dimensions.

Since the full-sized image is being loaded anyway, it results in wastage of bandwidth, which could have been saved. Data transfer is not cheap.

In addition to increasing your bandwidth bills, it also costs your users real money. If you are using an image CDN, you can further reduce your bandwidth consumption by serving images in next-gen formats e. Resizing large images to fit a smaller container is expensive and can be painful on low-end devices where both memory and processing power is limited.

This slows down the whole web page and degrades the user experience. When implementing web pages, images need to fit the layout perfectly. Here is what you need to remember to be able to implement responsive designs:.

Try ImageKit. There are a couple of downsides of client-side image resizing, mainly poor image quality and slower image rendering. To overcome this, you should serve already resized images from the server. Responsive image which adjusts based on available width You can specify the width in percentage instead of an absolute number to make it responsive. To achieve this, you can use: Background image object-fit css property Resizing background image background-image is a very powerful CSS property that allows you to insert images on elements other than img.

You can control the resizing and cropping of the image using the following CSS attributes- background-size – Size of the image background-position – Starting position of a background image background-size By default, the background image is rendered at its original full size.

The first value sets the width, and the second value sets the height. If only one value is given, the second is set to auto. For example, px px or 50px. It also has 2 special values contain and cover : background-size:contains contains – It preserves the original aspect ratio of the image, but the image is resized so that it is fully visible.

Along with inherit , initial , and unset , there are 5 more possible values for object-fit: contain : It preserves the original aspect ratio of the image, but the image is resized so that it is fully visible.

The image will fill its given area, even if it means losing its aspect ratio. Slow image rendering Since the full-sized image is loaded anyway before resizing happens in the browser, it takes more time to finish downloading and finally rendering. You can see this download time on the network panel, as shown in the screenshot below. Poor image quality The exact scaling algorithm used by the browser can vary, and its performance depends upon underlying hardware and OS.

Bandwidth wastage Since the full-sized image is being loaded anyway, it results in wastage of bandwidth, which could have been saved. The user friendly dashboard will also show you how much bandwidth you have saved so far See the actual savings in the ImageKit dashboard 4. Increased memory and processing requirements on client devices Resizing large images to fit a smaller container is expensive and can be painful on low-end devices where both memory and processing power is limited.

Summary When implementing web pages, images need to fit the layout perfectly. Here is what you need to remember to be able to implement responsive designs: Avoid client-side browser resizing at all if you can. This means serve correctly sized images from the server. It results in less bandwidth usage, faster image loading, and higher image quality.

There are many open-source image processing libraries if you want to implement it yourself. Or better, you can use a free image CDN which will provide all these features and much more with a few lines of code. Never upscale a raster image i.

You should use the SVG format for icons and graphics if required in multiple dimensions in the design. While resizing, if you want to preserve the aspect ratio of original images – Only specify one of width and height and set the other to auto. If you want the image to fit the entire container while preserving the aspect ratio, even if some part is cropped or the image is upscaled – Use the object-fit CSS property or set a background image using the background-image CSS property.

Control the starting position of the image using object-position while using object-fit. In background images, use background-position.
