Even though the image cannot be compressed completely, the size and resolution still need to be balanced. The file size increases with increasing resolution. Using high-resolution photos online slows down page load times. Similarly, if a visitor uses a mobile device to access your website, bandwidth is probably more limited, and larger graphics will take longer to load.
The ideal approach is to strike a balance between file size and quality. The image should be scaled down to the smallest size possible while maintaining the desired visual effect. Additionally, if you need to show large, high-resolution photos, load the entire image only if requested by the user.
What is image resizing?
You can resize the image to make it bigger or smaller without removing any content. Resizing an image changes its dimensions, which often has an impact on file size and image quality. Reducing the size of huge pictures to make it easier to share via email or online is the most popular justification for shrinking photos.
Simply throwing away pixels is how an image is reduced in size. Alternatively, increasing the size of the image adds more pixels, which can degrade the quality. Highly magnified images may be pixelated or blurry. This is due to the resolution, or level of fine detail in an image, when the size of the photo is larger than the original. When in digital format, resolution in photography is sometimes given as pixels per inch (ppi).

Adjusting photos for blogs and website
Blogs and websites usually have a recommended size for their photos to maintain the crispness and ensure that they are displayed in line with the content. If you do not pay attention to the size of the image, then you get to see the difference in the speed of your website and the user experience also gets disturbed.
When you upload a large image to be displayed at a much smaller size, such as a 2500*1500 pixel image displayed at a 250*150 pixel size, the entire image still needs to be loaded, leading to longer loading times. There could be a significant increase. Therefore, scale the image to the desired aspect ratio.
Why is image resizing important?
Large images can greatly slow down your website, and it is completely unnecessary to have an image larger than what your site supports. Site speed is important because most users will not wait more than three seconds for a website to load.
