The more the pixels in the image, the heavier will be the file size. Considering the market trends, all the camera manufacturers are trying to market their products on the basis of higher megapixel count. Having more pixels is always a good and safe option, as we can always compress or resize the image as per our requirement.

One of the easiest and fastest ways to resize or compress an image is using Adobe Lightroom software. In this post we are going to discuss some of the common situations when you might need to resize or compress images, and how to use Lightroom 5 for the same.

Situations when you need to resize or compress images

While uploading photos on social media:

Do you know, if you upload a 4000x3000px photo on Facebook it is automatically resized to 2048px (width) and the height is proportionately adjusted. Similarly when you upload the same photo on Instagram, you image is resized to 1080px (width) and the height is adjusted according.

While submitting photos for photography competitions:

In majority of photography competitions you are asked to submit photos with file size of under ‘x’ MB, but you realize that the original file is way heavier than required. By compressing the file size, you can make a copy of the original photo and submit it for the competition.
