What could be causing the image in Webflow to not display properly in IE11?

TL;DR
  • Use JPEG, PNG, or GIF instead of unsupported formats like WebP.  
  • Avoid modern CSS like object-fit and grid; use div backgrounds and older layouts instead.  
  • Ensure fallback <img> tags are present in <picture> elements.  
  • Disable animations or interactions not supported in IE11.  
  • Clear IE11 cache or use InPrivate mode to test cleanly.

Images not displaying properly in IE11 is typically caused by unsupported image formats, modern CSS features, or Webflow-specific limitations that Internet Explorer 11 doesn’t recognize.

​

1. Check Image Format Compatibility

​

  • IE11 does not support WebP. If your image is in WebP format, it won’t render in IE11.
  • Use JPEG, PNG, or GIF for full compatibility with Internet Explorer.

​

2. Ensure Correct Display Settings

​

  • Check that the image is not set to display: none when viewed in IE11. Legacy browsers might misread some flex/grid alignment rules.
  • In Webflow, verify image container styles are compatible with older layout systems—avoid display: grid unless fallback styles exist.

​

3. Verify CSS Properties and Vendor Prefixes

​

  • Some modern CSS (like object-fit, advanced filter, or mix-blend-mode) may not render correctly or at all in IE11.
  • If you used object-fit: cover, it will break in IE11. Instead, use background images on a div for compatibility.

​

4. Confirm Webflow Browser Support Limitations

​

  • Webflow’s Designer and some animation features don't fully support IE11. Interactions or animations can conflict with basic rendering.
  • Try disabling animations and checking if the image displays.

​

5. Fallback Content and Image Delivery

​

  • If you are using the <picture> element with <source type="image/webp">, IE11 will not fall back unless an <img> is also included as a final element.
  • Always include a fallback image inside <img>, and ensure Webflow renders it properly.

​

6. Test in a Clean Environment

​

  • Sometimes IE11 caches broken elements. Clear cache or test in InPrivate mode.
  • Try using developer tools in IE11 to inspect if the image tag is even being rendered and if the src attribute is being respected.

​

Summary

​

To fix image display issues in IE11, use standard image formats (JPEG/PNG), avoid modern CSS properties, confirm interaction compatibility, and ensure fallback images are properly structured. IE11’s limited support requires simplifying styles and avoiding modern HTML/CSS features that aren't backward-compatible.
