How to Shrink File Size of JPG or JPEG

You might find it necessary to use or send a smaller image size in various situations, such as when sending an email attachment, uploading an image to a website, or saving phone space. However, the key question is how can you decrease the file size of a JPEG/JPG without compromising its quality. In this article, we will guide you on precisely how to shrink the file size of JPG/JPEG without losing much quality.

When you compress any image, you’ll lose detail and clarity. However, the results are often so amazing that it takes a trained eye to notice the differences.

Reduce JPG File Size Online

One of the greatest advantages of online tools has always been their accessibility from any device, whether a phone, tablet, or computer. Now, to reduce the size of the JPEG file, we will use this amazing tool called ImageResizer. To use it, you need to upload the image by clicking on the Select Image button.

Upload the image

Next, enter the image dimensions and select the image format. If you prefer to skip these steps and directly reduce the JPG file size to, let’s say, 100 KB, enter the desired size in the Target File Size box (Keep in mind that this may significantly impact your image quality because it doesn’t change the image resolution accordingly).

After that, hit the Export button, and it will begin processing the picture. To download the image, click the tiny download button under the New Size column.
