6 Best Practices for Magento 2 Image Compression

1. Choose the Right Image Format

• Selecting the appropriate image format helps balance quality and file size.

  1. JPEG is best for product images. It supports lossy compression and smaller file sizes

  4. GIF is suitable for animated images but heavy on bandwidth

• Use WebP for product images to achieve high quality with a smaller file size.

• Set appropriate dimensions based on where images are displayed:

  1. Product pages: 800x800px or 1000x1000px for zoom functionality

  2. Category thumbnails: 300x300px
