How to Reduce the Size of an Image Using Photoshop Finally, notice that our image size started as 17.2M (megabyte) and increased to 24.7M with the enlargement. In this example, we enlarged our image by increasing the document size from 10" x 6.667" to 12" x 8" Also note that the pixel dimensions changed from 3000 x 2000 to 3600 x 24000. Images will look smoother or more soft with this method.Ĭongratulations! You have now successfully changed the size of your image! By selecting bicubic smaller, we are telling Photoshop to interpolate (or create new pixel information) that will produce the best results when enlarging images.īicubic (best for smooth gradients) - Very precise method that calculates the averages of surrounding pixels.īicubic Smoother (best for enlargements) - Based off of Bicubic sampling and works best when enlarging images that have high image noise. What does this mean? Basically, Photoshop will have to create new pixel information in order to enlarge the image. In this example, we increased the document width from 10" to 12" and the height from 6.667" to 8".īefore hitting OK, we will want to select our resampling method. We want to keep the 300 resolution, so all we need to do is type in new pixel or document dimensions. Lets say we wanted to enlarge this image to a 12" x 8" so that it can easily be printed and framed. Enter new pixel dimensions, document size, or resolution. An Image Size dialog box will appear like the one pictured below.Ĥ. I’d recommend you to use : When enlarging images, it is recommended to clean up dust and scratches or any noise before enlarging because these items may be magnified in your enlarged image.ģ. Quick and easy, how to compress a JPEG without changing dimensions. I have now reduced the file size by 76%, which obviously, if I do that across all the images I use on my site, will have a big impact on the overall load times and performance of the website. And if I open up this image, you can see that without affecting image quality, or the dimensions of the image, these are still the same dimensions. And that was the same thing here with the image with 80%. And now you can see negative 76%, which means that it has reduced the file size by 76%. But now I’m just going to upload with this compress. I’ll let it upload you can see I all ready did one image here. If I just go here to show you, so Upload file, I can just pick any image here that I have on my computer. It’s a quick and easy tool that accomplishes that. It’s really simple and easy,, and it allows you to compress an image, which is compress the image, reduce the file size, without actually changing the dimension. One of the problems is when you go to change an image, usually one of the ways that it’s recommended to optimize is to reduce the pixel width and length, or otherwise change the dimensions of the image which can really screw up the layout of your website. That really helps with performance and load times of your overall website. So this is something that we commonly run into when we’re building websites, is we need to actually optimize our site, and one of the biggest things to do that is to optimize your images on your site.
