What is the Image File Size?

Before learning about photo compression, let’s figure out the basics. It is important to know this to understand the key point of the process. File size, or otherwise weight, is measured in megabytes or kilobytes. It’s very important to understand that there are 1024 kilobytes in 1 megabyte.

File sizes depend on various factors:

  • The size of the photo is determined in pixels. If the picture has a size of 7360x4912 pixels, then its weight will be 5.2 megabytes. By reducing the image to 150 pixels, its weight will decrease to 75.7 kilobytes.
  • Image format: JPG, TIFF, RAW.
  • Several graphic details: you need to remember that the heavier the picture, the greater its weight.

Why Should you Compress Photos for the Website?

The main purpose of an image compression is to delete or group certain parts of the file to reduce its size.

A photo size compression procedure may be required in different situations. The most common is the publication of images and graphics on a website. The need to reduce the weight of the photo arises for the reason that too heavy images slow down the page loading process. If the site loads slowly, users don’t like it, and they go to competitors. Most often, the need for file compression occurs in such cases.

Smaller files take up less space on the server, so the site loads quickly and does not make the user wait.

Other reasons for photo compression:

  • Free up space in the internal storage of a mobile phone, tablet, or computer.
  • Reduce the weight of the image to send by email, and upload to certain sites (for example, to social networks).

If you do not compress photos, the user may encounter such problems:

  1. The site pages will take longer than three seconds to load, which will lead to a drop in conversions. Even if a person has high-speed Internet, he will not be able to upload photos with a lot of weight. If the user opens the site on his smartphone and from the mobile Internet, the page will load very slowly. As a result, the person leaves the resource, and you will lose a potential client.

  2. Internet traffic will be gone quickly, which people will not like. It will take more Internet traffic to upload heavy photos. If a person has a tariff with a limited amount of Internet, then he will spend precious bytes to download your site. No one will like it either.

  3. You will not be able to upload photos to a third-party resource that has restrictions on the weight of images. For example, if you need to post an image on a social network or another platform where there are pre-set limits on the weight of images.

Properties of Compress Photo JPEG, PNG, GIF

Image compression is aimed at reducing the weight of the image with or without loss of quality. There are different image compression algorithms for the two methods. However, the general essence remains the same. To reduce the weight, certain service data is removed from the file. For example, colors that are repeated or other elements.

Worth mentioning that the optimization of image size in most cases does not affect the visual component of the picture. Especially if we talk about how the picture will look on the monitor screen. The changes will be more noticeable when printing images. However, you don’t need to compress images to print them.

Lossy compression applies to JPEG and GIF formats:

  • When compressing JPEG photos, certain fragments of the image are eliminated. If you choose a high compression ratio, it will be visually noticeable. However, if you choose the compression with the best quality, then this will have a minimal effect on the quality of the photo.

  • The system determines independently which parts will be removed during compression. As a rule, aspects of the human visual system are taken into account, which always gives preference to visual information. Therefore, secondary elements always fade into the background. For this reason, the system removes them to reduce weight. That is, color, brightness, contrast – these details are practically not affected.

JPEG compression is suitable for photos in which the detail size is larger than the pixel size. Just, in this case, the image quality will not change when compressed.

GIF compresses files by reducing the number of colors. If there are 256+ of them in the picture, then the format will make the picture less attractive. However, our application will do its best to preserve the visually high quality of the image.

Lossless compression means that when the image is saved after compression, the quality will remain the same. This principle of photo compression concerns the PNG format. When compressing images in this format, their small size and all the details are preserved. When a person opens a picture, all its parameters will be saved.

If you choose the compression quality correctly, you can reduce the weight of images by 90% or more. And this will make it much easier to upload them to the site or send them by email.
