What Results in the Error “Post-Processing of Image Failed”?

Several things happen when you add an image to a post or the media library on your WordPress website. A PHP image editing module does some post-processing once an image file is uploaded to your WordPress hosting server, a page for the attachment is created, and the picture

Unfortunately, there are situations when WordPress may display an error message similar to this one during the image upload process:

Fortunately, this WordPress error notice gives a lot of information. It tells you that the problem happened during the post-processing of pictures in WordPress and suggests that the problem may be with your web server.

The error notice also offers a potential fix. It tells you to send a picture that is smaller than 2500 pixels wide and 2500 pixels tall.

With that stated, let’s look at how to resolve the WordPress problem “Post-Processing of Image Failed.”

1. Confirm that the HTTP error is not a temporary one.

To begin with, ensure that there are no special characters, such as an apostrophe, in the file name. You should rename the picture file if it does.

Then, after a little delay, try uploading your picture file once again. As the notice said, if your server was just too busy, it could have been because of a lot of traffic or a lack of server resources.

On the majority of WordPress hosting servers, issues of this kind are immediately resolved.

After some time has passed and the picture upload is still giving you trouble, you may try uploading an alternative file. Using a new web browser or clearing your browser’s cache are some options you could try.

If the “Post-Processing of Image Failed” message still appears, the issue is not a short-term bug, and you should continue reading for troubleshooting.

2. Increase WordPress’s Memory Limits

The error message implies that there may not be enough resources on your server. Let’s boost the RAM that WordPress has at its disposal.

You will need to increase the server’s Memory limit so that PHP may utilize more of it. The following code should be added to your wp-config.php file to do this.

define( 'WP_MEMORY_LIMIT', '256M' );

This code raises the memory limit to 256MB, which should be enough to fix any memory limit problems.

You may also want to see whether the file exceeds the maximum upload size for your website.

3. By optimizing the photograph, you can reduce its size.

A smaller picture may be uploaded, according to the error notice. It advises keeping your image’s longest edge to no more than 2500 pixels.

Many novice bloggers just upload their photographs without optimizing them for the web when they first launch their blogs. This might not only result in an error notice like this one, but it can also slow down your website due to the big-picture files.

Your overall SEO rankings will suffer if your website is sluggish.

Using an image editing program, you must resize the picture to a lower size, compress the image to make the file size smaller, and save the image in the best file format (such as JPEG, PNG, or GIF).

It’s important to notice that sometimes, even when uploading smaller photos, this error message appears. You will need to go to the next stage of troubleshooting if you see the issue even while uploading optimized photos.

4. Make changes to the WordPress Image Editor Library.

WordPress uses the GD Library and ImageMagick PHP modules to post-process pictures. Depending on which is accessible, WordPress may utilize any one of them.

However, ImageMagick sometimes has memory problems that might result in difficulties while uploading images. You may resolve this by setting the GD Library as your default image editor.

Simply adding this code to your theme’s functions.php file or a site-specific plugin will 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 picture again after adding this code.
