Provides easy admin access to define maximum width and height of uploaded images. Uploads exceeding these dimensions will be resized accordingly. Only the defined maximum size will be stored on the server. This way you will be able to save space and bandwidth on your webserver, while serving the pages faster to your visitors due to the reduced image size.
Watermark your precious images with the Professional extension, keeping track of them in the internet. New uploads can automatically be marked or you can add/remove watermarks via the Media Library. Unmarked copies of images are kept inaccessible to the public in case you want to restore it.
- Original aspect ration of uploaded images will be kept, preventing automatic cropping.
- Optionally specify a suffix to be added to names of resized images, eg upload of too large image “test.jpg” will be stored as “test_resized.jpg”.
- Set quality for resized images, allowing to save further space and bandwidth.
Further functionality is available as Professional extension:
- Select image sizes to watermark, eg to exclude thumbnails.
- Mass-add/-remove watermarks for already uploaded image attachments.
- Chose location of the watermark on the image and maximum width/height to cover.
- Supports GD Library and ImageMagick (Imagick)

Video tutorial: Explaining all plugin settings in the admin area
How does this plugin help compared to WPs default scaling of uploads?
By default WordPress limits the upload of images to max 2560px width/height, without providing any admin options to adjust this setting. This plugin allows you to disable this default and replace it with a setting accessible via the admin options.
This plugin additionally allows a customized suffix for resized images, compared to the unchangeable default “-scaled” suffix.
Also the plugin can prevent creation of additional intermediate sizes of all uploaded images, which due to their dimensions of 1536px and 2048px would be taking up much additional space on your webserver.
What is the ideal image to use as a watermark?
You should use a PNG image as watermark with transparent background. Try it out locally over various backgrounds/ images – light ones as well as darker ones.
The size depends largely on the size of your images to be marked. You can save a larger copy of the watermark PNG and limit the maximum space to cover via the plugin options. Make sure your watermark is still readable/ visible also when scaled down.
Why can only JPG / JPEG images be watermarked?
Simple answer: Most images used in the internet are in the JPG format. Watermarking JPG images should meet most users needs.
Technical answer: Other image formats can contain information and have special characteristics making their handling very tricky and error-prone. For example: PNG files can contain transparency levels, additionally they can be animated. Similar for GIF images.
Honest answer: To limit complexity of the plugin 😉
