Are you sick of spending hours resizing and repositioning product images?

If so, this guide to streamlined batch image resizing is a must-read!

In this post, we'll go over the basics and check out how online tools can make your life easier. We'll also share some nifty tips for avoiding blurred photos, resolving errors, and resizing like a pro!

Understanding the Basics of Batch Image Resizing

Resizing images involves changing the dimensions, either with or without resampling—more on the differences between the two in a minute!

Regardless of the method, many tools allow you to upload and resize one file at a time. However, very few support batch resizing images.

The tools that can handle multiple images are incredibly convenient, especially if you need to edit eCommerce product photos.

After all, tackling this sort of task would be extremely time-consuming. Instead, batch processing tools like use AI algorithms to simplify the process, allowing you to resize entire collections of images in just a few clicks.

The Impact of Resizing on Resolution

Now, you're probably aware that resolution refers to the number of pixels in an image, but how does resizing affect it? Well, not all resizing processes are created equal.

Resizing by resampling involves adding or removing pixels. Meanwhile, resizing without resampling means changing the dimensions without altering the data/pixels.

One common misconception is that upscaling/upsampling will improve image quality. Unfortunately, it can do just the opposite. That's because the AI-powered tool basically has to guess what the added pixels should look like based on limited data. 

That doesn't mean you can't get decent results with resizing tools, though. The key is starting with a high-quality source image!

Using Online Tools for Batch Resizing Images

Some people use downloadable software, like Adobe Photoshop, for resizing. To process large collections, they need to use Automated Actions or image batch resize scripts on the Image Processor dialog box.

That said, this isn't the only option.

There are online tools that handle batch image resizing—no Photoshop skills are needed. These tools can be more convenient for many users.'s Content-Aware Scale and Resize tool, for example, is an excellent choice for streamlined bulk processing. It relies on an AI algorithm that can automatically align your product photos or flat lays to meet the marketplace standards.

The Smart Resizer might also scale images to match the desired output sizes regardless of the original image composition or orientation.

Plus, the tool does more than just resizing and aligning. It'll help you remove backgrounds as well!

Step-by-Step Guide to Batch Resizing

Follow these simple steps to resize images in bulk using's online tool:

1. Create an Account

2. Open the Bulk Image Resizer

Next, look for the Content-Aware Scaling + Background Remover workflow in

It might be better to name the project right away. It'll only take a moment and will make finding the projects much easier later!

3. Adjust the Resize and Scale Settings

The tool will walk you through the different settings, including the background removal options. But for now, we'll focus on configuring the resize features.

Here's what you'll need to tweak around:

  • Margins: Using percentages, add enough vertical and horizontal space to make sure that the image is centered away from the edges. Keep an eye on the preview to see how the margin values look on the image.
  • Preserve side contact: Enable this feature if you don't want the tool to reposition objects touching any of the edges.
  • Output size: Here, you can choose multiple custom image sizes, and they'll be added to your workflow for future use. Note that if the original and output aspect ratios differ, the tool will automatically pad the images to maintain the relative size.

4. Upload the Batch and Wait for the Automated Retouching

Finally, you can upload your image files (JPG or PNG) via drag-and-drop or file selection.

All you need to do next is to click "Start Crop" to begin resizing the batch based on your set parameters. The platform's AI will automatically handle aligning, scaling, and optimizing each image.

When that's done, select all images and download the resized batch of images to your computer. 

Tips for an Effective Batch Image Resizing Process

Now that you know the basics of batch-resizing images, you're ready for some pro tips!

1. Start With High-Resolution Images

We've covered how resizing affects the quality level, but you're not entirely helpless here.

To avoid blurry outputs, you need to pick high-resolution source images. So, double-check that you're uploading the original files, not the thumbnail versions!

2. Work Around Margin Preview Errors

Suppose the margin preview doesn't update automatically. In this case, the fix might be as simple as closing and reopening the project.

If you still have trouble with the preview, try refreshing your browser, as this often fixes display glitches.

Don't hesitate to contact our support team if you can't get the preview to work properly.

3. Know Your Site's Guidelines

Did you know that Amazon requires the product to take up 85% of the image? However, not all sites run on the same guidelines.

Don't underestimate the importance of incorporating background removal into your workflow—it's a massive time-saver.

Believe it or not, you could save 8–10 minutes per image!
