What is the image resolution?
As far as I know, the secondary image resolution is made up of a unit called Pixels. Pixels color cells are very, very small in size and in the number of hundreds, tens of thousands of pixels will create an image. Number pixels The more in an image, the clearer the image and vice versa.
But the photos you like do not always meet the resolution needs. Some sites like Facebook will have a minimum resolution requirement for photos. What happens if your photos do not meet the requirements?
How to change image resolution?
Would you try to change the resolution of that photo? However, changing the image resolution manually can cause the image to be blurred, broken, and no longer clear. pixels has been “stretched”.
Because basically we have no deep knowledge about images. So arbitrarily changing the resolution manually will not be suitable and cause bad effects on the image. I will help you to solve this problem.
To solve that, today I will show you how to increase the image resolution and still keep the quality. Of course, we will ask for the help of software developed by experts.
