Common Mistakes to Avoid When Resizing Images Online and How to Fix Them

In today’s digital age, having the ability to resize images online is an essential skill for anyone working with visual content. Whether you are a blogger, a social media manager, or a business owner, chances are you’ll need to resize images at some point. However, there are common mistakes that people often make when resizing images online. In this article, we will discuss these mistakes and provide solutions on how to fix them.

Using the Wrong Image Format

One of the most common mistakes people make when resizing images online is using the wrong image format. Different image formats have different properties and purposes. Using the wrong format can result in poor image quality or unnecessarily large file sizes.

For example, if you are resizing an image for web use, it’s best to use a format like JPEG or PNG. JPEG files are ideal for photographs as they compress well without significant loss of quality. On the other hand, PNG files are great for graphics and illustrations as they support transparency.

To fix this mistake, always consider the purpose of your resized image before choosing a format. If you’re unsure which format is best for your needs, try experimenting with different formats and compare their file sizes and visual quality.

Ignoring Aspect Ratio

Another mistake people often make when resizing images online is ignoring aspect ratio. The aspect ratio refers to the proportional relationship between an image’s width and height. Resizing an image without considering its original aspect ratio can result in distorted or stretched visuals.

To avoid this mistake, it’s crucial to maintain the original aspect ratio when resizing images. Most online tools provide options to either manually input specific dimensions or automatically maintain aspect ratio while adjusting one dimension.


If you need to resize an image while maintaining its original aspect ratio, simply enter either the desired width or height value and let the tool automatically adjust the other dimension accordingly.

Overcompressing Images

While it’s important to optimize image file sizes for web use, overcompressing images is a mistake that can lead to loss of quality. When an image is excessively compressed, it can appear pixelated or blurry, which can negatively impact the overall user experience.

To avoid overcompression, pay attention to the compression settings when resizing images online. Find a balance between reducing file size and maintaining visual quality. Most online tools have options to adjust compression levels or provide a preview of how the image will look at different compression settings.


Remember to strike a balance between file size and image quality. It’s better to have slightly larger file sizes if it means preserving the integrity and clarity of your visuals.

Not Saving a Copy of the Original Image

One crucial mistake that many people make when resizing images online is not saving a copy of the original image. Resizing an image permanently alters its dimensions and potentially its quality. If you don’t keep a backup of the original image, you may not be able to revert back if needed.

To fix this mistake, always make it a habit to save a copy of your original image before resizing it. This way, you can easily revert back or make further adjustments if necessary without compromising the integrity of your visuals.


In conclusion, when resizing images online, it’s important to avoid common mistakes such as using the wrong format, ignoring aspect ratio, overcompressing images, and not saving a copy of the original image. By being mindful of these mistakes and following the provided solutions on how to fix them, you can ensure that your resized images are visually appealing and optimized for their intended purpose.
