Do you want to make sure your images are optimized as soon as you upload them to WordPress? Uploading large, uncompressed images can slow down your site and affect performance, especially on mobile devices. By optimizing images during the upload process, you can reduce file sizes without losing quality, which helps your pages load faster and improves the overall user experience.
With the Nexter Extension (Free) and Nexter Extension (Pro), you can resize and optimize the images while uploading.
This is a Freemium feature. If you are using the free Nexter Extension version, you can resize the image to reduce the file size.
With the Nexter Extension Pro, you can resize the image and set the image quality as well.
Best Used For:
- Photography and portfolio sites that regularly upload high-resolution images
- E-commerce stores where product image file sizes affect page load speed
- News and media sites with high-volume daily uploads
How to Optimize an Image with the Nexter Extension Free?
To optimize an image while uploading with the free Nexter Extension, from the WordPress Dashboard, go to Nexter > Extensions > Performance.
Then go to the Image Upload Optimize section, enable the toggle and click on the gear icon (⚙).

It will open the Image Upload Optimize pop-up.
Set the maximum width and height (in pixels) for uploaded images. Use this when you want to automatically limit image dimensions across the entire site without manually resizing files before each upload.
Click the Save button when done.

When you upload an image, it will be resized automatically based on its aspect ratio in JPG format. The resize applies whichever dimension is larger: the maximum width or the maximum height you set.
Note: If you don’t want to resize any image, add “-ne” to the file name—for example: “photo-ne.jpg”, it will not be resized while uploading.
For example, if both the maximum width and height are set to 500px:
- If you upload an image with 1000px X 600px, it will be resized to 500px X 300px to fit the width.
- If you upload an image with 800px X 1200px, it will be resized to 333px X 500px tall to fit the height.
This way, your image will be resized, maintaining the original aspect ratio.
Note: This will not affect the old uploaded images.
How to Optimize an Image with the Nexter Extension Pro?
To optimize an image while uploading with Nexter Extension Pro, open the Image Upload Optimize pop-up.
Set the maximum width and height (in pixels) for uploaded images. Use this when you want to automatically limit image dimensions across the entire site without manually resizing files before each upload.
Set the Image Quality value between 1 and 100. Higher values produce better image quality but result in larger file sizes. Use a value between 70 and 85 for a good balance of quality and file size on most sites.
Click the Save button when done.

When you upload an image, it will be resized automatically based on its aspect ratio. The resize applies whichever dimension is larger: the maximum width or the maximum height you set.
