How do I reduce image sizes in Magento?

To reduce image sizes in Magento, you can follow these steps to optimize the images and improve your site's performance. Here are a few methods:

1. Use Image Optimization Tools

Use image optimization tools to reduce the file size of your images without compromising quality. Some popular tools include:

  • TinyPNG: Compress PNG and JPEG images.
  • ImageOptim: For Mac users, it optimizes images by removing unnecessary metadata.
  • An online tool that provides image optimization and compression.

2. Implement Lazy Loading

Lazy loading helps to load images only when they are about to be displayed in the viewport, reducing the initial page load time.

Steps to Implement Lazy Loading:

  1. Install a Lazy Load Extension:

    • Search for a suitable lazy load extension in the Magento Marketplace or use a third-party extension like "Mageplaza Lazy Load."
  2. Configure the Extension:

    • Once installed, go to the Magento admin panel.
    • Navigate to Stores > Configuration > [Your Extension Provider] > Lazy Load.
    • Configure the settings according to your preferences.

3. Resize Images Before Upload

Ensure that your images are appropriately sized before uploading them to your Magento store. Large images can significantly impact page load times.

Steps to Resize Images:

  1. Use an Image Editor:
    • Use image editing software like Photoshop, GIMP, or online tools like Canva to resize images to the desired dimensions.
  2. Maintain Aspect Ratio:
    • Maintain the aspect ratio of images to avoid distortion.

4. Leverage Content Delivery Network (CDN)

Using a CDN can significantly speed up the delivery of images by caching them on servers closer to your users.

Steps to Use a CDN:

  1. Choose a CDN Provider:
    • Providers like Cloudflare, Akamai, or Amazon CloudFront offer CDN services.
  2. Configure the CDN:
    • Follow the provider’s instructions to integrate the CDN with your Magento store.

5. Optimize Image Formats

Choosing the right image format can also impact the file size. For example, use JPEG for photographs, PNG for images with transparency, and SVG for icons.

6. Use Magento’s Built-in Image Optimization

Magento has built-in capabilities to optimize images, which can be configured in the admin panel.

Steps to Optimize Images in Magento:

  1. Go to the Admin Panel:
    • Navigate to Stores > Configuration > Advanced > Developer > Image Processing Settings.
  2. Enable Image Optimization:
    • Set the "Image Processing" options to the desired optimization methods like GD2 or ImageMagick.


  • Use image optimization tools like TinyPNG, ImageOptim, or
  • Implement lazy loading using extensions.
  • Resize images before uploading.
  • Leverage a CDN for faster image delivery.
  • Optimize image formats based on content type.
  • Configure Magento's built-in image optimization settings.

By following these steps, you can effectively reduce image sizes in your Magento store, improving load times and overall performance.
