Most of the blog themes come with content area width of 600-700px or maybe less or more depending on the theme, so make sure you know the content area width to create a perfect image.
The above section tells you the proper image dimensions but what would you do when you download a stock image that is too large in dimensions?
If you have downloaded a stock image and it’s too large in dimensions, then it is better to resize it and then upload it. Don’t upload the image in its original size and resize it using the height and width parameter in your post editor.
If you upload the original image and then resizing it from the post, then you are doing no good. When the page is loaded in the browser, the images will load to its original dimensions and size and then it will be resized. This will only increase the loading time of your page.
There are online tools like PicResize and PicMonkey that you can use to resize your images before uploading them to your article.
When you use stock images of high quality, you will be adding a lot of pressure on your server to simply load the images. The higher the quality of the image, the more will be its size.
If the image you want to upload is in triple digits in KB or it is in MB, then that’s because the quality of the image is too high.
It is possible for the dimensions of the image to be around 500 x 500px and still be large in size. At such moments, you can’t simply resize the picture; you need to compress them for lighter weight.
There are tools like TinyPNG that helps you in compressing the images to reduce the size. Even after compressing the images, it won’t affect the image quality much. The image will still look good and it won’t be distorted or pixelated.
