WP Imsizer (short for Image Resizer) is a plugin for <a href="https://wordpress.org/" rel="ugc">WordPress</a> which will save you and your clients or fellow blog contributors from having to manually resize all of your images to a more visitor friendly size. You can even restrict the total file size of uploaded images and even disable the <a href="https://make.wordpress.org/core/2019/10/11/updates-to-image-processing-in-wordpress-5-3/" rel="nofollow ugc">WordPress image 2560px threshold limit</a> which was introduced in version 5.3.
When someone uploads an image that is larger than your set dimensions, WP Imsizer will automatically scale it down to your desired pre-configured size and replace the original image.
Now can automatically set filtered image upload Alt, Title, Caption, and Descriptions from filename. Filters out hyphes, underscores, commas and extra spaces. Also, automatically capitalizes each word and will disable the default WordPress insertion of Titles from filenames.
The <a href="https://wordpress.org/plugins/wp-imsizer/" rel="ugc">WP Imsizer Plugin</a> is ideal for WordPress web sites and blogs that do not require super high resolution images. This will save space on your server, speed up your page speed performance, and reduce bandwidth utilization for both you and your visitors. As a result of being able to quickly display your media on your web site, this will most likely <a href="https://moz.com/learn/seo/page-speed" rel="nofollow ugc">improve your search engine ranking</a>.

WP Imsizer

A handy plugin for any WordPress web master wanting to help their clients with reasonably sized image uploads. This keeps their web site images to a reasonable dimension (one that we can set) for optimal page speed performance. It will also disable WordPress' 2560px image dimension threshold limit. An annoying feature since it keeps the original but renames the main use image with -scaled. No way to remove the original (besides manually) which is usually in the MegaByte file size range. Overall great little plugin. But don't take my word for it, I'm biased. ;)

Regaining Control of our Images

Auto resize/convert image uploads to set height/width or file type. Auto set image alt, title tags, limit file size and disable 2560px limit.
