Top 10 Best Applications to Compress Your Photos in 2021

Users often find themselves in a position where they have several images they want to keep, but the space requirement for those is in Gb’s. So, you have no option other than deleting them to make some space on your HDD.

However, there are options to optimize these images to make them low in size. So, you can use them with ease over the internet, and it will cost you around one-third of the disk space.

How to select the best services and applications for image compression

The internet has many image-compression tools, and there is an enormous number of tools available. But, only some of these applications are good.

The image compression means that some information in the original image is discarded during the compression process. Its effects will be visible if you zoom the image. So, it is best to choose an application that has these characteristics.

Choose the application which reduces the size to one-third of the image

The recommended size for a website by Google is less than 1Mb. So, all images, gifs, markup, and code should be below 1Mb. You have to choose an application that reduces your image size to at least one-third of its original size.

High-speed compression of images in less time

It is most likely that you have to compress versions of the same image and test them out on your website before finalizing them. So, time efficiency is a must thing.

Keep an eye on the other features an application provides

The users seldom use only the image compression feature. The features like exporting, resizing, and adding multiple images are the best ones in an application.
