In this case, the size of the photo is relatively large, because it is rich in detail and varied. A lower quality would probably have worsened the photo too much. To finally evaluate the picture, I go to save. Unfortunately you can not see a preview of the picture before saving. Around 420KB are already much more acceptable than 2, or 9MB. Because this is still too big for my terms, I go down a lot with the quality control. Now I can see that the file size would be only 2MB. To change that, I go to File > Export.įirst, I change the format to JPEG. My picture is 9MB in PNG format, which is way too big for a website. This is usually the standard program with which images are opened. In order to reduce the size of an image under MacOS, the image must be opened with "Preview". Thus, relatively little quality is optically lost, while at the same time the file size drops significantly. For this photo I have set the quality to 60%. At the same time you can see the size of the file and a preview of the photo. Here you can lower the quality of the photo. Click on save to open the quality configuration: Here you have to change the file type from PNG to JPEG. Then, I go to File > Save As.Ī window including the file browser is opening.

Scaling under Windowsįor scaling on Windows I use the program Paint.NET. On this page you can insert your URL and test how fast your page loads. To get an idea of how big your site is at the moment and how much of it pictures are taking, there are tools like the Pingdom Website Speed Test. Although 20KB are little, but the quality of the photo suffers too much. Left 20KB, right 180KB (both JPEG format).
Often, large images are still necessary, especially when it depends on small details.
The smaller the file is, the harder it is to recognize something in the picture. There is always a trade-off between image quality and file size. In the end, this also affects the size of the file. Next, with image editing programs, the quality of the image can be adjusted. The format with the extension "PNG" is usually larger than a compressed format like "JPEG". Image files can be modified in various ways to affect the size of the file. 2MB are about the acceptable frame in which you should move, because: If a page loads for too long, users may also stop the loading. However, websites can be larger or smaller, depending on how many images they contain. This is still fast to load on the way and does not consume too much data. For my part, I try to make posts no bigger than 2MB in total. So how big should pictures be? That depends. In this case, the mostly limited data volume is used up very quickly, if you often visit pages that contain non-optimized images. This can be particularly problematic when surfing with the smartphone while having poor Internet connection. If the page contains several large image files, you can easily get to 20-50MB that want to be loaded. If you embed images into a website, your device will need to load all data, including images, when the page is opened. Each image file has a size in kilobytes (KB), megabytes (MB), or maybe even gigabytes (GB). In order to visualize posts, it makes sense to include pictures and screenshots that fit the topic of the post. Why should images be as small as possible? This post contains the ones I always use. Of course there are also alternative programs and tools that can be used to change and analyze image files.

This guide will explain why it makes sense to scale images on websites and how to do it on Windows and MacOS.Įspecially with number13 I scale images very often so that the posts do not get too big.
