Is your WordPress displaying the ‘Post-Processing of Image Failed’ error?

As you probably know, when you try to upload an image in WordPress, you get the upload image failed to load. In my case, this happened overnight, and while I know something must have changed or been updated, I couldn’t tell you what it was. The problem was that the image I was trying to upload definitely fit the size requirements listed in error. It was just 1000px wide. So there was something else going on. This problem commonly happens when you use the built-in media uploader to upload an image file to WordPress.

Why ‘Post-Processing of Image Occur Error?

When you add an image to a post or the media library on your WordPress website, several things happen. The image file is uploaded to your WordPress hosting server, an attachment page is generated for the picture, and some post-processing is performed via a PHP image editing module.

When uploading a picture to your WordPress site, you may encounter a notice like this one: The error notice also provides a workaround. It suggests that you submit a smaller image with the longest dimension of no more than 2500 pixels. With that out of the way, let’s look at how to solve the ‘Post-Processing of Image Failed‘ problem in WordPress.

How to Fix the Post-Processing of the Image Failed Error

Below we represent four methods to solve this issue. Here are step-by-step instructions on how to fix the error using cPanel, the interface that comes with your hosting package.

1. Confirm that the HTTP error is not temporary

  • To begin, ensure that there are no special characters in the file name, such as an apostrophe. If this is the case, you should rename the picture file.

  • After that, wait a few minutes before attempting to upload your image file again. If your server was merely busy, as the notification implies, it might have been due to exceptional traffic or a lack of server resources.

  • On most WordPress hosting servers, issues like this are immediately resolved.

  • If you’re still having picture upload problems after a while, try uploading a different file. You might also try clearing the cache in your browser or using a different web browser.

  • If the ‘Post-Processing of Image Failed’ error persists after doing these procedures, the problem is not a momentary malfunction, and you should continue debugging.

2. Extend the WordPress Memory Limit

  • The error message implies that your server may be lacking in resources. Let’s boost the amount of RAM accessible to WordPress.

  • You will need to raise PHP’s RAM limit on your server. You can do this by adding the following code to your wp-config.php file.

  • define(‘WP MEMORY LIMIT, ‘256M’); This code raises the WordPress memory limit to 256MB, which should be sufficient to resolve any memory limit concerns.

  • You should also check to see whether the file is greater than the upload limit on your website. See our tutorial on how to raise the maximum file upload size in WordPress for more information.

If your WordPress hosting provider does not enable you to increase the RAM limit, you may need to migrate to a managed WordPress hosting service such as SiteGround or WP Engine.

3. Reduce the size of the image by optimizing it.

  • According to the problem notice, submitting a smaller picture may assist. It advises that your image’s longest edge has no more than 2500 pixels.

  • Many novice bloggers just upload photographs without optimizing them for the web when they first start a blog. Not only might this result in an error notice like this one, but huge picture files will also slow down your website.

  • A sluggish website will lower your overall SEO ranks.

  • To optimize the image, use image-editing software to save it in the appropriate file format (such as JPEG, PNG, or GIF), scale the image dimensions to a lower size, and compress the image to reduce the file size even further.

  • See our article on how to optimize photos for online performance without sacrificing quality for step-by-step instructions. This section discusses picture optimization, as well as the best tools and strategies for image optimization.

  • It’s worth noting that this error message might appear even when uploading smaller photos. If the issue persists even after uploading optimized photos, proceed to the next stage of troubleshooting.

4. Modify the Image Editor Library of WordPress

  • WordPress uses two PHP modules to post-process images: ImageMagick and GD Library. Depending on which is accessible, WordPress may utilize any of them.

  • ImageMagick, on the other hand, might have memory difficulties, which can result in mistakes during picture uploads. You may remedy this by making the GD Library your default image editor.

  • Simply add this code to your theme’s functions.php file or a site-specific plugin to do this.
function wpb_image_editor_default_to_gd( $editors ) {
    $gd_editor = 'WP_Image_Editor_GD';
    $editors = array_diff( $editors, array( $gd_editor ) );
    array_unshift( $editors, $gd_editor );
    return $editors;
}
add_filter( 'wp_image_editors', 'wpb_image_editor_default_to_gd' );

You should try uploading the image again after adding this code.
