Understanding Resize Modes

Cover Mode

Fills the entire frame, cropping excess parts

✓ Best for:

  • • Background images
  • • Landscape photos
  • • When subject is centered

✗ Avoid for:

  • • Images with important edge content
  • • Text or logos near edges
Contain Mode

Fits entire image, adding white space if needed

✓ Best for:

  • • Product photos
  • • Infographics
  • • When nothing can be cropped

✗ Avoid for:

  • • Backgrounds (looks unfinished)
  • • When white space is undesirable

Best Practices

  1. 1.
    Start with high resolution

    Use images at least 1920px wide for best quality after resizing

  2. 2.
    Consider safe zones

    Keep important content in the center 80% of the image to avoid cropping issues

  3. 3.
    Test on mobile

    Most social media is viewed on phones - verify your images look good on small screens

  4. 4.
    Optimize file size

    Use WebP or JPEG at 80-85% quality for faster uploads and loading

  5. 5.
    Maintain aspect ratios

    Don't force images into incompatible aspect ratios - choose the closest preset

  6. 6.
    Batch process

    Create multiple sizes at once for different platforms to save time
