For example, on high resolution (2x) displays, high resolution graphics ensure sharpness. Responsive web design means that not only can our layouts change based on device characteristics, but content can change as well.
With responsive web design not only can our layouts change based on device characteristics, but images as well. But they also often account for most of the downloaded bytes. Place text in markup instead of embedded in imagesĪ picture is worth 1000 words, and images play an integral part of every page.Use media queries to provide high res images or art direction.Use image-set to provide high res images.Use media queries for conditional image loading or art direction.Art direction in responsive images with picture.Enhance imgs with srcset for high DPI devices.Tada! Now you're ready to rock and roll and resize your images like a pro.
I reduced the file size by exporting it as a JPEG and manually dialing down the quality to 37KB (but it still looks good for web!) In the below example, I began with a PNG image that was 346KB. Here's what I typically do on my Mac, using Preview.Ĭhoose JPEG as your file type, and set the quality manually to reduce the size even more. The easiest way is to use the "Save for Web" option if you're in Photoshop or an editor that has that option. Next, make sure you save the image correctly. If your image is 3000 pixels wide, you should bump it down to a more manageable size. If your file is super huge, like 10MB, you probably need to do step #1 and check on those dimensions. PNG files or JPG files can get pretty hefty, but you can reduce the file size a couple of ways. My file size is too big and will take a long time to load.Įxample: My image is 900KB, how can I make it smaller so it loads more quickly? "But wait, that's not what I mean!" you say. Pixlr, MS Paint, or Photoshop have very similar cropping tools. So, start with a bigger image, dimensionally, to crop and resize. Note: If you start with a smaller image, you'll need more than this simple tutorial. It will look like this as you crop:Īnd that's how you crop and resize to a required dimension. Next, with the selection tool, select and crop the height to 309. For this example, I set the width at 504 pixels, but you'll notice that makes the height 336 pixels. Open your file, Select Tools > Adjust Size. Sometimes, your image has to be cropped or adjusted before you can resize, so that your final dimensions are correct.Įxample: This image is 770 x 514 and to resize it to an exact dimension like 504 x 309 I'm going to have to crop. I can't just change the dimensions!Īh, here's the rub.
Select Adjustments > Resize.Įnter dimensions and constrain proportions. This will give you the option to change the image to the right dimensions.īrowse and open your file. Open the file, click Tools > Adjust Size. My image is the wrong dimension for the space.Įxample: This page needs an image that is 504 pixels wide by 309 pixels high. This can actually have a few different meanings. First, here are some photo editing tools to help you do the job, if you need them.īut what does it mean when someone says "I need to resize this photo." Yes, "How can I resize this photo for my website?" is our #1 head-scratcher of an issue, and it's high time we provided a tutorial to make resizing easier for everyone. Wait, maybe you've already figured it out because you read the title of this post. You will never guess what our support team says is the #1 question they get from our clients.
