How to count the number of pixels in an image

If you need to find out how many pixels are in an image in total, then it’s easy to calculate: just multiply the width by the height. Those. if the image has a width of 600 and a height of 600, then multiply 600 * 600 and get 360000 px.

How to find out the size of a picture

There are several different image formats. Once you know the format of the image and its size, you can wisely use it for posting on your own website. For example, did you know that for pictures with few sharp transitions it is better to use the JPG format, and for photographs with increased sharpness – the PNG format?

This article will discuss ways to find out the size of a picture, the main graphic formats that are used on the Internet, and their differences. The most common image formats include JPG, PNG, SVG and GIF.

Due to the characteristics of different formats, each specific picture may be a good option in one situation and a bad option in another. In addition, once you know the size of the image, you can decide whether it is worth uploading it to the site – depending on how much the image weighs, it can have a positive or negative effect on behavioral factors.

Too large images will interfere with fast loading of the site, and thereby increase the bounce rate, worsening the site’s ranking in search results. Low-quality, uninformative and poorly attractive images will also negatively affect the promotion of an Internet resource in search engines.

Using a large number of photos can also worsen the site’s ranking, so you should wisely select the sizes and compress the necessary images, trying not to lose quality.

Knowing the size of pictures is important because their weight affects the loading speed of the site, which in turn affects promotion.

To find out the weight of a photo saved on your computer, just look at its “Properties”. Right-clicking on the image and selecting the appropriate item in the context menu will display a corresponding window with information about the width and height of the photo in pixels. The resolution in DPI will also be shown here.

if you need to know the size and resolution of several images at once, open the “View” tab, then select the “Details” format and check the “Resolutions” box. This will let you know the size of each picture.

To find out the size of a photo posted on the site, use the following instructions:

  1. If you are using the browser Mozilla Firefox
    — right-click on the picture, then select “Image Information” from the context menu. This action will display an information window that will show the original size of the image and its modified version that is used on the site.
  2. If you are using the browser Google Chrome
    — right-click on the image, then select “View element code” from the context menu. In the window that appears after this, the size of the picture will be visible (on the right side in a colored frame). Or hover your mouse over the selection in the right window, then the image size will appear above the selected image.
  3. In modern versions of the browser Opera
    You won’t be able to find out the image size using the built-in tools. But there is a way out! Install the add-on “ Classic Images”
    , with which you can find out the type, size, resolution and address of the picture. The algorithm of actions is the same as in the Firefox browser – right-click, then select “View image properties”.

Nowadays there are four main graphic formats used on the Internet – JPEG, PNG, SVG, GIF. Each of them has its own characteristics and is used for certain situations. Let’s look at each image format in more detail.

The most common image format. Best suited for photographs and pictures without sharp transitions. When compressed, it may lose quality, which is why the user is offered a choice of several options for the final quality (high/medium/low).

The second most popular format. P NG is often used for graphic pictures and illustrations. A distinctive feature of this format is that when the image is compressed and enlarged, it does not lose quality. In addition, it is actively used for pictures with sharp, not smooth transitions.

This format is used for two-dimensional vector graphics and is widely used throughout the world. It is especially popular when developing modern websites. SVG files take up much less space compared to images saved in other formats.

The main disadvantage of this format is that it is quite difficult to create complex objects that cannot be described using geometric shapes.

Takes up a lot of space and can slow down the site on weak computers. However, it is used to create GIF animations. This format can be useful when used in instructions or other content formats in which it is important to demonstrate the step-by-step completion of a task.

It is important to know the size of pictures for internal website optimization. Reducing the size of the images used will increase the site loading speed, which will have a positive effect on SEO. It’s important to try to reduce the size of your images without losing quality, and you also need to know which image format will work best for your situation.

To find out the image size, most often you just need to right-click and select the appropriate context menu item. The Opera browser may require the installation of an additional extension.
