Thanks for the article.

An alternative that I found out after trying out a few things (only for people who use the Smush plugin) is to enable ” Resize my full size images” in Smush and enter a higher value.

THE SOLUTION IS AS FOLLOWS:

1. In WP Go to >> Media >> dropdown list in dashboard heading >> Add New (don’t use the Add New from within the Library)
2. If the Upload New Media is set to the multi-file uploader, then switch to the browser built-in file uploader.
3. Using the single file uploader WORKS and solves the problem

You will be able to see which Uploader you are using as follows:

2. If you see this:

You are using the browser’s built-in file uploader. The WordPress uploader includes multiple file selection and drag and drop capability. [OR] Switch to the multi-file uploader.

Maximum upload file size: 32 MB.

Then your uploads will work

3. If you see this:

You are using the multi-file uploader. Problems? Try the browser uploader instead.

Maximum upload file size: 32 MB.

Then click on the link to use the browser uploader.

Then you are using

UPDATE: I used WP Downgrade to go back to WP Core version 5.2.5 and the issue immediately went away.

I’m convinced that WordPress Core’s new “big image” handling feature, which was implemented beginning with version 5.3, is somehow broken.

I had already tried to fix this by clearing all server caches, and checking error log and debug log (nothing showed at all regarding today’s date). Nothing helped except downgrading.

Again, here’s the page (with discussion) about the new feature:

https://make.wordpress.org/core/2019/10/09/introducing-handling-of-big-images-in-wordpress-5-3/

Summary: I think this new feature broke our multisite (no way to upload big images), and downgrading WordPress Core to 5.2.5 fixed the issue.

WordPress Core Team, please help!

Hi,
I have the same issue on my website. I have two images and both resolutions are higher than 2500.
one image is 3300 and is png image and is uploading fine.
the other one is 7600 and is a jpg image and shows this error.
“Post-processing of the image failed. If this is a photo or a large image, please scale it down to 2500 pixels and upload it again.”
I tried all the methods but nothing works for me.

Any suggestions, please?

    If you need to upload images larger than 2500px, I suggest you to upload the image on your hosting directly. Then collect the link of images to use on your website. You will also find plugins that helps to upload image directly to your hosting, not in wordpress directory. So, you can try the method.

      Actually my customers will upload their own images, and customer don’t know how to scale images. also, they don’t have permission to the admin side.

        Did you try to disable the big image issue using the code on your function.php file?

        add_filter( ‘big_image_size_threshold’, ‘__return_false’ );
