Very useful: How to make images weigh less

In this brief tutorial we will explain how you can make the images smaller, either because you want to occupy less space on your hard drive or directly because you need to send them to someone and obviously our goal is to make them as light as possible so as not to have problems during the process. Whatever your reason, we are going to give you a series of tips that we are convinced will help you to have much lighter images.

Choose a suitable format type

As many of you can already imagine, today we can choose from a wide variety of image formats, which are presented with a series of characteristics that define them and make, depending on the use for which the image is intended, some more interesting than others.

In our case, the objective is to send an image losing the minimum quality but achieving that it weighs the minimum possible, and for it we are going to focus on three main formats that are GIF, JPEG and PNG.

Obviously, in order to change the format of the image we are going to need a specialized program. In our case, a short time ago we were analyzing the so-called Light Image Resizer, one of the most interesting alternatives that will allow us to choose between these three formats that we will discuss below as well as many others.

Characteristics of the GIF format

We started with the GIF image format, a widely used alternative that you will surely know thanks to the fact that it also allows you to save animations.

Without a doubt it is a very valid option, but it is important to point out that we are talking about a format that perhaps has become a bit old-fashioned, not because it has a lot of time behind it, but because this standard is limited to a maximum number of colours that are 256 for each image, which can make that, although the image itself does not lose quality practically after compression, this reduction of colours can create an aspect that is not as beautiful as we would like it to be.

In short, if we are dealing with images with few colors, the GIF format may be interesting, but if it is an image that we want to keep the colors in addition to quality, perhaps we are interested in any of the two formats that we will discuss below.

Characteristics of the JPEG format

This is perhaps one of the most commonly used formats when compressing images for emailing, uploading to websites, and so on.

The reason is that it is perhaps the format that is going to allow us a greater compression, that is to say, the JPEG format will be the most indicated for those who want to compress to the maximum an image obtaining that it weighs the minimum possible, but care, since in this case we are going to lose a little bit of quality of image.

It should be noted that this format works phenomenally well in the case of images that have many colors and gradients. An example of this type of image would be when we capture a landscape or take pictures with our friends on the beach, in the mountains, and so on.

If we are going to send a normal image for other people to see as our family, friends, co-workers, etc., this format is going to be very helpful, but if the goal is to get the highest image quality is respected, the most interesting alternative will be the PNG format.

Characteristics of the PNG format

In third place we have the PNG format that we could basically understand as the new GIF format, since it is also compatible with animations and we will barely lose image quality, but in this case we are not going to be limited by the palette of 256 colors maximum. However, we must also bear in mind that with this format we will be able to maintain the maximum quality and colors, but we are not going to achieve the compression or achieve that the image does not weigh as if we would do it with the JPEG format.

So, what do you think about How to make images weigh less?
