Troubleshooting Animated GIFs in WordPress: Fixes and Optimization Tips

animated gif not working in wordpress

Adding a GIF to a WordPress post or page is a great way to enhance your content with engaging, animated visuals. WordPress offers several methods for inserting GIFs, including using the built-in Image block in the Gutenberg editor or embedding GIFs from external hosting services. However, users often encounter issues such as GIFs not animating, displaying only as static images, or failing to upload due to file size limits.

This guide covers the most effective ways to add GIFs on WordPress, explains why GIFs sometimes fail to play or animate, and provides troubleshooting steps to resolve common problems. We’ll also discuss best practices for optimizing GIFs for performance, how plugins and WordPress settings can affect GIF behavior, and how solutions like Cloudinary can help you manage and deliver animated GIFs efficiently on your site.

Understanding Why GIFs Fail to Play in WordPress

The problem can be rooted primarily in how WordPress processes images during upload. WordPress typically creates several sizes of any uploaded image to ensure that the best size is used depending on where it’s being displayed.

This is great for static images, but it can unintentionally strip away the animation for animated GIFs. If WordPress compresses the GIF to different sizes, only the full-size file retains the animation. As a result, if a theme or post uses a thumbnail or a medium-sized version of the image, the animation will not appear.

Another common issue comes from file alterations during the upload process. If you edit a GIF in WordPress—cropping it, for instance—it might be saved as a single frame rather than a looped animation. This is because most built-in editing tools in WordPress are not designed to handle the properties of animated files.

How to Add a GIF on WordPress Using the Image Block

To add a GIF to a WordPress post or page using the Gutenberg editor, follow these steps:

  1. Navigate to the Post or Page: Open your WordPress dashboard and go to the post or page where you want to insert the GIF.
  2. Add an Image Block: Click the “+” icon to add a new block and search for “Image.” Select the Image block.
  3. Upload or Select Your GIF:
    1. Upload: Click “Upload” and select the GIF file from your computer.
    2. Media Library: Click “Media Library” to choose an existing GIF already uploaded to your site.
  4. Insert and Adjust: After selecting the GIF, insert it into your content. In the block settings, ensure the image size is set to “Full Size” to maintain the animation.This method ensures your GIF is embedded correctly and remains animated in your published content.

Embedding GIFs from a Hosting Service

Alternatively, you can embed GIFs hosted on external platforms (like Giphy or Imgur) by copying the embed code or direct image URL and inserting it into a Custom HTML block or directly into the editor. This can help bypass WordPress file size limits and preserve animation.

Why Your GIFs Aren’t Animating in WordPress

The issue often lies in how the GIF is served on your site. First, ensure that the GIF you uploaded is indeed animated. This is a basic step, but it’s crucial. Before uploading, open the file on your computer or an online viewer to verify that it plays as expected.

Next, check the file size and dimensions. WordPress has limitations on the media upload size, which, if exceeded, could lead to the server resizing or rejecting the file. This resizing can strip the animation from a GIF. Always ensure your files comply with the upload limits, and consider compressing large GIFs before uploading them to avoid automatic resizing.

If you’re sure the GIF is fine, the next step is to examine how WordPress handles the file. When you select the GIF in your media library and insert it into a post, choose the ‘Full Size’ option. This selection ensures that WordPress uses the original file, not a resized version. Choosing a resized image, as mentioned, will likely display a static frame instead of the animation.

Image optimization plugins are fantastic for speeding up your site by compressing images, but they can interfere with GIFs. These plugins might optimize the GIF by reducing its size, which can remove the animation. If you suspect this might be the case, try temporarily turning off image optimization plugins and re-upload your GIF to see if it resolves the issue.

How to Fix an Animated GIF Not Working in WordPress

Ensure GIFs are Set to Full Image Size in the Editor

The first and perhaps most crucial step is to ensure that your GIF is set to display at full size within the WordPress editor. To maintain the animation, always choose the full-size option. This prevents WordPress from using a resized—and likely static—version of your GIF, ensuring the animation remains intact. It’s a simple but effective fix that often gets overlooked in the rush to publish content.

Re-upload the GIF via the WordPress Media Library

If your GIF still isn’t animating, consider re-uploading it. Sometimes, initial uploads can encounter glitches or errors that affect the file. Remove the existing file from your WordPress Media Library, ensuring you delete all instances of it from the library and any posts. Then, upload the GIF again, selecting it directly from your computer rather than dragging and dropping, which can sometimes alter file integrity. Once uploaded, insert it into your post as a full-size image and check if the animation works. This process can often reset any issues and get your GIF moving.

Reduce GIF File Size for Improved Performance

Large GIF files can be problematic in WordPress, not only because they can exceed upload limits but also because they can slow down page load times, impacting user experience and SEO. Use an external tool to compress your GIFs before uploading them. Tools like Cloudinary offer sophisticated image and video management solutions, including automated GIF compression that reduces file size without significantly impacting the visual quality or animation. Smaller, optimized files are less likely to be automatically processed by WordPress in a way that could remove animations.

Disable Image Optimization Plugins

While image optimization plugins are great for speeding up your WordPress site, they can strip animations from GIFs. If you’ve tried the above steps and your GIFs still aren’t animating, temporarily turn off any active image optimization plugins. After deactivating them, re-upload your GIF and check if the animation persists. If this resolves the issue, you might need to adjust the settings of your optimization plugins to exclude GIF files from being processed or switch to a plugin that explicitly supports animated GIFs.

In my experience, here are tips that can help you better troubleshoot and optimize animated GIFs in WordPress:

  1. Use MP4 video format as an alternative for large GIFs
    Animated GIFs are resource-heavy and can slow down your site significantly. Instead of using large GIFs, convert them into MP4 video format. MP4 files are more efficient in terms of file size and bandwidth. Cloudinary offers automatic conversion tools that can transform a GIF into a lightweight MP4, providing smoother animations while drastically reducing file size.
  2. Implement lazy loading for animated GIFs
    Animated GIFs can impact page load times, especially if there are multiple on a single page. Use a lazy loading plugin like WP Rocket or Lazy Load by WP Rocket to load GIFs only when they enter the viewport. This will improve initial page load times and prevent users from experiencing lag or sluggishness as they scroll through your content.
  3. Set clear width and height attributes for GIFs
    Ensure your animated GIFs have defined width and height attributes in the HTML or CSS. Undefined dimensions can cause layout shifts, impacting your site’s visual stability and negatively affecting the Core Web Vitals score for Cumulative Layout Shift (CLS). Explicitly defining these attributes will help maintain a stable layout as the page loads.
  4. Use GIFs sparingly to avoid overwhelming users
    Overusing animated GIFs can distract users and slow down your page, especially on mobile devices. Keep their usage to a minimum and prioritize meaningful or visually impactful animations. Consider using them in specific areas like tutorials, instructional posts, or to highlight essential content, rather than as background elements.
  5. Leverage the Cloudinary auto-upload feature for media management
    Use the Cloudinary WordPress plugin to automate your GIF uploads directly to Cloudinary. Cloudinary’s auto-upload feature handles compression, format conversion, and delivery via a Content Delivery Network (CDN). This ensures your GIFs load quickly and are served from the nearest location to the user, reducing latency and improving performance.
  6. Pre-optimize GIFs before uploading to WordPress
    Before uploading any GIF to WordPress, run it through an external optimization tool like Ezgif, GIF Optimizer, or Cloudinary’s online transformation tool. This pre-optimization step ensures the GIF is already lean, reducing the likelihood of WordPress making further, unintended modifications that might remove the animation.
  7. Enable Cloudinary’s responsive image delivery for varying screen sizes
    GIFs often need to be resized for different devices and screen resolutions. Cloudinary’s responsive image delivery automatically adjusts the GIF size, format, and quality based on the user’s device. This ensures that smaller versions of the GIF are served on mobile devices, reducing data usage and improving load times.
  8. Exclude GIFs from auto-compression in image optimization plugins
    Image optimization plugins like Smush, ShortPixel, or Imagify can inadvertently compress and strip animations from your GIFs. Configure these plugins to exclude GIFs from compression, or set up a rule to skip any files with the .gif extension. Alternatively, switch to a plugin that explicitly supports GIF compression while preserving animations, like Optimole.
  9. Use a GIF-to-SVG converter for simple animated graphics
    If your animated GIFs are relatively simple (e.g., vector-based logos or icons), consider converting them to SVG animations. SVG files are much smaller, support interactivity, and can be scaled without loss of quality. Using SVGs instead of GIFs can provide a smoother, faster experience, especially for high-DPI displays.
  10. Monitor GIF performance and engagement using analytics
    Use tools like Cloudinary’s analytics or Google Tag Manager to track how users interact with your animated GIFs. Knowing which GIFs perform well and which slow down the page can guide future content decisions. Consider removing or replacing underperforming GIFs with optimized alternatives to enhance user experience and site performance.

Implementing these expert tips will ensure that your animated GIFs are not only visually appealing but also optimized for performance, delivering a smoother and more engaging experience to your WordPress site visitors.
