Whether you’re a beginner or a seasoned WordPress user, our step-by-step guide will help you tackle this issue with ease. So, let’s dive in and ensure that your images are processed flawlessly on your WordPress site.

Check the Image File Size

To fix the post-processing of image failed error in WordPress, you should check the image file size. This error often occurs when you try to upload an image that exceeds the maximum file size limit set by WordPress or your hosting provider.

To check the image file size, you can right-click on the image file on your computer and select ‘Properties’ (on Windows) or ‘Get Info’ (on Mac). Look for the file size information, which is usually displayed in kilobytes (KB) or megabytes (MB).

If the file size exceeds the limit, you can try reducing the image size using an image editing tool or compressing the image using a plugin.

Increase PHP Memory Limit

Are you experiencing the ‘post-processing of image failed’ error in WordPress? This error can occur when you try to upload or process images on your website.

One possible solution is to increase the PHP memory limit in WordPress. The PHP memory limit determines how much memory can be allocated to PHP scripts on your server, and increasing it can help resolve the error.

To increase the PHP memory limit, you can edit the wp-config.php file in your WordPress installation. Locate the line that says ‘define(‘WP_MEMORY_LIMIT’, ’64M’);’ and change the value to a higher number, such as ‘128M’ or ‘256M’. Save the changes and try uploading or processing the images again.

If the error persists, you may need to contact your web host to further increase the PHP memory limit.

Disable Plugins and Themes

Try disabling any plugins or themes that could be causing conflicts with image processing in WordPress.

Sometimes, certain plugins or themes may interfere with the image processing functionality of your WordPress website, resulting in the ‘Post-Processing of Image Failed’ error.

To identify the problematic plugin or theme, you can deactivate all your plugins and switch to a default WordPress theme (such as Twenty Twenty-One). Then, try uploading or processing an image again to see if the error persists.

If the error disappears, you can reactivate your plugins and themes one by one, testing the image processing after each activation, until you find the specific one causing the conflict.

Regenerate Thumbnails

You can easily resolve the ‘Post-Processing of Image Failed’ error in WordPress by regularly regenerating thumbnails using a reliable plugin.

This error occurs when WordPress fails to process the image thumbnails during the upload process. It can be caused by various factors such as incorrect file permissions, memory limits, or conflicts with other plugins or themes.

Regenerating thumbnails involves recreating all the different image sizes that WordPress uses, ensuring that they’re generated correctly. To do this, you can use a plugin like ‘Regenerate Thumbnails’ which is specifically designed for this purpose.

Simply install and activate the plugin, then go to ‘Tools’ in your WordPress dashboard and click on ‘Regenerate Thumbnails’. This will regenerate all your image thumbnails, fixing any post-processing errors that may have occurred.

Verify File Permissions

To resolve the ‘Post-Processing of Image Failed’ error in WordPress, check and ensure that the file permissions are properly set for your images. Incorrect file permissions can prevent WordPress from processing images and lead to the error message.

To verify the file permissions, you need to access your WordPress site’s files through an FTP client or a file manager in your hosting control panel. Navigate to the wp-content folder and right-click on the uploads folder.

Select the ‘File Permissions’ or ‘Change Permissions’ option. Make sure the permissions are set to 755 or 750 for folders and 644 or 640 for files.

Once you have adjusted the file permissions, refresh your WordPress site and try uploading or processing the images again. This should resolve the ‘Post-Processing of Image Failed’ error caused by incorrect file permissions.

Clear WordPress Cache

To clear the WordPress cache, navigate to the settings menu and locate the option for cache management. In WordPress, caching is a technique used to store static copies of your website’s content, including images, to improve loading times.

However, sometimes this cached data can cause issues, like the post-processing of image failed error. Clearing the cache can often resolve this problem.

Once you’ve found the cache management option, click on it and look for the option to clear or purge the cache. This will remove any stored data and force WordPress to generate new versions of your images.

After clearing the cache, try uploading the image again to see if the error persists. Clearing the WordPress cache is a simple yet effective way to troubleshoot the post-processing of image failed error and ensure smooth image processing on your website.

Update WordPress and Plugins

After clearing the cache, it’s important to update WordPress and plugins to ensure the smooth processing of images on your website. Outdated versions of WordPress and plugins can often lead to errors in post-processing images.

To update WordPress, go to your WordPress dashboard and click on the Updates option. If there’s a new version available, you’ll see a notification. Click on the Update Now button to install the latest version.

Similarly, to update plugins, go to the Plugins section in your dashboard and check for any available updates. Update each plugin individually by clicking on the Update button next to the plugin name.

Keeping your WordPress installation and plugins up to date is crucial for preventing post-processing errors and ensuring the optimal performance of your website.

Contact Hosting Provider

If you experience ongoing issues with post-processing image failures in WordPress, contacting your hosting provider is recommended. The error could be related to server configuration or limitations that are affecting the image processing functionality. Your hosting provider will have the expertise to investigate and resolve any server-related issues that may be causing the error.

They can also provide guidance on optimizing your WordPress installation to prevent future post-processing image failures. When contacting your hosting provider, be sure to provide them with specific details about the error, such as the error message displayed and any steps you’ve already taken to troubleshoot the issue. They’ll then be able to assist you in resolving the post-processing image failed error in WordPress.


In conclusion, by following the steps outlined in this article, you can easily resolve the ‘Post-Processing of Image Failed’ error on your WordPress website.

From checking image file sizes to regenerating thumbnails and verifying file permissions, each solution is designed to help you identify and fix the root cause of the issue.
