Images have to be resized for several reasons: to submit in an application, to post on social media, to reduce file size, etc. 

But installing new software for such work that you do once in a couple of months is not ideal at all. There are several online platforms that allow users to edit, crop, resize, nd ltyer their images efficiently. This saves both your time and your storage. 

In this blog, we will explain how you can resize your images online, tools that are best for this work, and some tips to maintain good image quality after resizing.

What Do We Mean When We Say “Resize an Image”?

When we talk about resizing an image, what it includes is changing the width, height, or twice of them of the image. 

This means that we take a large-sized image and resize it to a smaller size to fit a particular place or site. An image’s dimensions are usually its width and height. That is measured in pixels. 

File size consists of the amount of storage space the image uses. This is something like 500 KB or 2 MB. The two are related, but they are different. When you decrease an image’s dimensions, the file size also reduces.

Why Do You Need to Change Image Size?

Changing an image’s size is very useful for different purposes. Changing an image size can make your file smaller and easier to upload. 

In many cases, websites and online platforms have specific image size requirements. You have to need to change the image size when uploading them to forms or any online application. 

Smaller images consume less storage space and upload more easily. In addition, for websites, resizing images can make the process quicker.

  • Avoid resizing the same image many times.

Common Problems When Resizing Images Online

Here are some common problems that appear when resizing images online. 

Blurred Image

Sometimes an image becomes blurred when you resize it. This happens because of insufficient pixels in the original image. Use ideal sizes when working with images.

Stretched Image

Images can look stretched out when their width and height ratios are too different. It is important that when you are resizing an image, you should maintain the original aspect ratio.

File Size Remains Too Large

Reducing the dimensions is not enough to decrease the file size sometimes. Smaller dimensions and lower image quality are also good for decreasing the file size. A good format can also help reduce file size.

Image May Get Cropped

Some image resizers crop parts of the image to keep it fitted in the selected dimensions. Check the default crop settings before resizing to ensure important parts of the image remain visible. 

Image Format Changes

Some applications change the format of the image while exporting. You should check the output format before downloading the resized image.
