What Is the File Size of a Photo

Each picture is made up of a large number of dots called pixels. Each pixel has its color, a combination of three primary colors (red, blue, and green). 1 pixel in an image has about 3 bytes. High-quality, detailed images can have millions of pixels. As a result, one such picture can take up millions of bytes on a computer, smartphone, or any other device.

When a camera takes a picture at 10 megapixels, it is assumed that there are 10 million pixels present. Simple calculations allow us to conclude that one such snapshot, when stored, will occupy at least 30 megabytes in the device’s memory.

Pictures with many pixels are clear, crisp, and detailed, but they take up a lot of memory on a device.

Also, difficulties may arise if you need to send such a picture by email. The download process may take a significant amount of time. If you reduce an image’s KB size, this will help to avoid these problems. What’s more, with the correct settings, the quality of the image will hardly diminish.

Why Reduce Image Sizes for Sites on the Internet?

Another reason to use an image size reducer tool is if you need to upload your image to a website. Images are an essential element of any site. Before reading an article, the user often skims the page and develops a first impression. The image is usually the element that initially attracts their attention.

Graphic elements on the page are liked by human visitors and search engine robots, which evaluate the page for ranking purposes. Google's latest SERP update added a more fruitful snippet. Now it's much easier to get to the top of search results using images.

The right graphic elements on the site will help improve the visibility and recognition of the web resource.

The human users who visit your site evaluate pictures according to the following criteria:

  • loading speed of all elements
  • image quality
  • connection with the topic of the article
  • informational value.

It is important to remember that each web page component takes up a certain amount of space on the server. The larger the elements, the slower the site will load. In some cases, perhaps when using mobile data, the page will not load at all due to a long wait time.

The act of reducing an image’s KB size optimizes the photo and makes it possible to significantly reduce the overall size of the site. Since images are one of the weightiest elements, optimizing them can free up to 80% of server space.

What Does Photo Optimization Mean?

The image size reducer is one of the processing options that allows you to reduce the size of the image by removing information, for example:

  • metadata
  • where the photo was taken
  • device name, etc.

This information is not essential to the average user, but it does affect the weight of the image.

The Watermarkly tool also uses state-of-the-art photo rating algorithms. They analyze the image and determine which graphic elements can be removed without compromising the visual experience.

How to Correctly Reduce Image Size

It all depends on your goals. As mentioned above, pictures are compressed to speed up sending emails, free up space on a device’s memory, and ensure a site's optimal operation.

For example, experts advise not to upload photos that weigh more than 500 KB to the site. The rule of thumb is to reduce an image’s KB size to about 100 KB. This way, the pages will load well even with a slow Internet connection.

Do not use images of 1 MB or more. They will degrade the performance of your site and deter visitors.

Reduce Image Size With and Without Quality Loss: What's the Difference

When using the image size reducer tool, two options are possible - with and without losing quality. What is the difference between these two options, and which is better to choose when processing your images?

With the loss of quality

The main goal of this processing option is to get an image of the minimum size. When implementing this approach, the considerations of the quality of the image are not taken into account at all.

Without losing quality

A compromise option in which the size is reduced, but the quality hardly suffers. If you look at two pictures - the original and the processed copy – it is highly unlikely that you will be able to notice much difference. The image is often not processed, and the size is reduced by deleting various data.

The critical point in choosing the best processing technique for you is your priorities regarding the quality or quantity of the stored information.
