How to Shrink Photo File Size: The Ultimate Guide

Irrefutably, images are part of the blood cells of our digital life. Whether it's social media, online accounts, or our workplace, we interact with photos daily.

Today, a friend or colleague would rather choose to share a photo via WhatsApp or whatever platform they love than print it out. While this comes with a lot of flexibility, it can also be limiting. This is because digital images are made of pixels, which take up space in our computer hard drives or online storage—the more pixels, the more space it'd require storing or uploading. Hence, the need to resize the photo size in some circumstances.

Why you may need to shrink your photo file size

  • Sharing purpose: We've all encountered "the image size is too large" warning when trying to share or upload a photo file. Mail clients, social media platforms, and online accounts have a photo size limit you can send or share. Shrinking the size can solve the hassle.
  • Site performance: If you're a developer or, in some way, you manage or interact with sites, you know how big images can adversely affect the site load time, user experience, and performance in general. Using small photos can save you a ton.
  • Storage saver: This can be considered when you're dealing with many images and may require software capable of compressing many image files at a go to reduce their overall file sizes.

How to shrink a photo file

Before we dive into how to shrink file size of photo, it's vital to understand the theory behind pixels. Pixels are tiny boxes, each with a specific color that builds up the picture. The number and size of pixels in an image determine the snap's quality (resolution) and file size.

Well, there are two approaches when shrinking a photo size — resizing and resampling. Resizing means increasing or decreasing the pixel size, while resampling means changing the number of pixels in an image. Each will result in less file size, but resampling does so without affecting the quality much.
