How to resize jpg images
I will teach you how to adjust the jpg image to the desired size in this article. I will tell you two ways to resize jpg images, compress big jpg images to a smaller size, and enlarge small jpg images to a bigger size without losing quality.
The Jpg image is not always the size you want. Sometimes you need a small size, and sometimes you need a large size, depending on how you want to use this jpg image. For the first situation, you will need to compress the jpg image. For the other situation, you need to enlarge the jpg image, keeping the jpg image’s quality simultaneously.
Image Compression
First, I will explain what jpg image compression is so that you can understand why you need to compress jpg images.
Photo compression reduces the size of jpg image files, which can take up less memory in the computer without affecting the quality of the jpg image.
There are several reasons why we need to compress jpg images:
- save space on your computer
- make it easier to send via e-mail or publish to the web because photos will take up less memory
- using the compressed images on the website could improve the website's running speed
There are a lot of jpg image compression tools on the market. Next, I will introduce you to a free online compression tool with good performance - TinyJPG.
TinyJPG
In this part, I will give a detailed introduction to TinyJPG in three aspects: what it is, how to use it, and the quality of the outcome.
What is it
TinyJPG is a free online compression tool. It uses smart lossy compression techniques to reduce the file size of the jpg image. By selectively reducing the number of colors in the jpg image, fewer bytes are required to store data. The effect on the jpg image’s quality is almost invisible. However, the file size is really different.

Quality
As the image shows, the left one is the original jpg image with the file size of 540kb, and the right one is the compressed jpg image size is 218kb. Although the size has been reduced by 59%, the program doesn’t cause any negative effect on the jpg image’s quality.
Image Enlargement
