Post-Processing of Image Failed Error in WordPress- How to Fix

Fix-Post-Processing-of-Image-Failed-Error-in-WordPress

Are you facing the post-processing of image failed errors in WordPress?

This problem commonly happens when you use the built-in media uploader to upload an image file to WordPress.

This post will demonstrate how to simply resolve the ‘Post-Processing of Image Failed’ upload problem in WordPress.

What’s the Reason for Having Post-processing of image failed error?

There are several things that happen on your WordPress website when a user adds an image to a post or the media library. The image file is uploaded to your WordPress hosting server, an attachment page is generated for the image, and some post-processing is performed via a PHP image editing module.

Unfortunately, you may get the following WordPress error notice during the image upload process:

Post-processing of the image likely failed because the server is busy or does not have enough resources. Uploading a smaller image may help. The suggested maximum size is 2500 pixels.

Fortunately, this WordPress error notification is fairly detailed. It informs you that the issue occurred during post-processing the image in WordPress and recommends that your web server may be down.

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 stated, let’s look at how to resolve the post-processing of image failed problem in WordPress.

By Checking Whether the HTTP Error is Temporary or Not

To begin, ensure that there are no special characters in the file name, such as an apostrophe. If this is the case, you must change the image file name.

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.

However, on most WordPress hosting servers, issues like this are immediately resolved.

If you’re still having image upload problems after a while, try uploading a new file. You might also start by clearing the cache in your browser or using multiple web browsers.

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.

By Optimizing the Image – Make it Smaller in Size

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.

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.

By Increasing WordPress Memory Limit

Your server may not have adequate resources, according to the error message. Therefore, you need to increase your memory limit. Let’s make more RAM accessible to WordPress.

You’ll need to boost PHP’s RAM limit on your server. To do so, add the below code to your wp-config.php file on WordPress.

define('WP MEMORY LIMIT', '256M');

This code raises the WordPress memory limit to 256MB, which should be sufficient to address any memory limit concerns.

By Changing WordPress’ Image Editor Library

WordPress uses two PHP modules to post-process images: ImageMagick and GD Library. Depending on which one is accessible, WordPress may utilize any of them.
ImageMagick, however, might have memory difficulties, which can result in mistakes during image uploads on WordPress. You may remedy this by making the GD Library your default image editor.
As a result, 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' );
Once you add the above code, try uploading the images again.
