My computer and phone are full of images!

Let’s explain in this brief tutorial how you can make the images weigh less, either because you want to occupy less space on the hard drive or because you have the need to send them to someone and obviously our goal is to do them as light as possible to upload them faster. Whatever your reason, we are going to give you a series of tips that we are convinced will help you to have much less heavy images.

The first thing I do after I take a pic with my smartphone is upload to Dropbox , this way they are saved in the cloud. After that I simply drag them to my pc from the dropbox folder.


As many of you already can 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 to which the image will be intended , Are some more interesting than others.

In our case, the goal is to send an image losing the minimum quality but getting as low as possible, and for this we will focus on three main formats that are GIF, JPEG and PNG.

Obviously, in order to change the format of the image we will need a specialized program. In our case, recently 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 are going to discuss next, as well as many others.


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

It is certainly a very valid option, but it should be noted that we are talking about a format that may have been somewhat outdated, not because of the fact that it has a lot of time behind it, but this standard is limited to a maximum number of Colors that are 256 for each image, which can make that, although the image itself does not get to lose quality practically after the compression, this reduction of colors if it can arrive to create an appearance not as pretty as we would like.

In short, if you are dealing with images with few colors, the GIF format may be interesting, but if it is an image that we want to preserve colors in addition to quality, we may be interested in either of the two formats we are going to Speak below.


This is perhaps one of the most used formats when compressing images to send by email, upload to web pages, and so on.

The reason is because it is perhaps the format that will allow us a greater compression, that is to say, the JPEG format will be the most suitable for those who want to compress an image as much as possible, so that it weighs the least possible, but be careful, since In this case yes we are going to lose some image quality.

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.

Having an external backup is “common sense” everything that is important for you should be double saved somewhere.

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



Thirdly we have the PNG format that we could basically understand as the new GIF format, as it is also compatible with the animations and we will barely lose image quality, but in this case we will not be limited by the palette of 256 colors at most . Of course, we also have to take into account that with this format we will be able to keep the quality and colors to the maximum, but we will not get the compression or get the image to weigh as if we would with the JPEG format.

An important detail of the PNG format is that it is especially suitable for those images that do not have excessive gradients and do not appear too many angular shapes. An example of this type of image would be for example when we photograph a textbook, when we realize screenshots, et cetera.

In summary, if we want the minimum weight we will use the JPEG format, if we want the maximum quality and colors to the detriment of a greater compression, the ideal will be the format PNG, and if we look for a mean that allows us a greater compression but with the limitation Of 256 colors, the alternative of the GIF format is what we are looking for.


Once we have made a decision regarding the image format we want to use, the next thing we will be to reduce its size.

Nowadays, both the digital cameras and the ones that carry the mobile phones, allow us to have quite high resolutions, which means that we can for example print a large image without fear of losing quality, but as in our case we are not going To make in principle impressions or, if it does, with a smaller dimension we would have enough, what we will do is choose a size that allows to see the image with a sufficient dimension but obtaining in this way that weighs much less.

Basically, an image will weigh more as you get bigger, regardless of the file format we have chosen.

Just as we used the program Light Image Resizer to change the image format, we will also be useful to change the size of the image, and all in the same process, thus achieving, in just a few seconds , Any image is perfectly prepared to be sent by e-mail or stored taking up as little space as possible. In addition, we can also modify several images at once, so ideal for large jobs.

Of course, we should not exceed the time to compress the image, because with this process there is also the risk of losing some quality, but it is clear that in most cases we will send images that do not need as many Characteristics and quality, so it is usual to choose a format of the type JPEG and a dimension of for example 640 × 480 px, so that we can get an image that weighs several megabytes to pass just a few kilobytes.
