# How to Optimize Image while Uploading in WordPress?

## Key Takeaways

- Nexter Extension (Free) allows users to resize images during upload to reduce file size without losing quality.
- Nexter Extension (Pro) enables users to set image quality values between 1 to 100 while resizing images on upload.
- Images uploaded with Nexter Extension are resized automatically based on the maximum width or height set by the user, maintaining the original aspect ratio.

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)](https://wordpress.org/plugins/nexter-extension/) and [Nexter Extension (Pro)](https://nexterwp.com/nexter-extension//), you can easily 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 version, you can resize the image and set the image quality as well.

## 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. 

You can set the maximum width and height (in pixels) of the image.

Once done, click on the **Save** button.

Now, when you upload an image, it will be resized automatically based on its aspect ratio in JPG file format. The resizing uses whichever is larger — the maximum width or height you’ve 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 the Nexter Extension Pro plugin, open the Image Upload Optimize pop-up.

You can set the maximum width and height (in pixels) of the image.

Then you can set the image quality. You can set the value between 1 to 100. Higher values give better image quality but increase file size.

Once done, click on the **Save** button.

Now, when you upload an image, it will be resized automatically based on its aspect ratio. The resizing uses whichever is larger — the maximum width or height you’ve set.

## Frequently Asked Questions

**Q: What should I do if my images aren't resizing when using the Nexter Extension?**
A: If your images aren't resizing, ensure that you've enabled the Image Upload Optimize toggle in the Nexter Extension settings. Go to Nexter > Extensions > Performance, and check the Image Upload Optimize section. If the toggle is on and the issue persists, verify that you're uploading images without the '-ne' suffix in the filename, as this prevents resizing.

**Q: What image quality settings should I use with the Nexter Extension Pro?**
A: With the Nexter Extension Pro, you can set image quality between 1 to 100. A higher value results in better image quality but increases file size. For web use, a quality setting around 70-80 often balances quality and performance well, ensuring images look good without significantly slowing down page load times.

**Q: What happens if I upload an image with dimensions larger than my set maximum?**
A: If you upload an image larger than the maximum dimensions you've set in the Nexter Extension, it will automatically resize while maintaining the original aspect ratio. For instance, if your maximum width is set to 500px, an image of 1000px width will be resized to fit within that limit, ensuring optimal performance.

**Q: Are there any limitations when using the free version of the Nexter Extension for image optimization?**
A: The free version of the Nexter Extension allows you to resize images but does not provide the option to adjust image quality. If you need to set quality levels for better control over file size and image clarity, consider upgrading to the Pro version, which offers this feature.

**Q: How do I prevent specific images from being resized during upload?**
A: To prevent an image from being resized when using the Nexter Extension, simply add '-ne' to the filename before uploading. For example, renaming 'photo.jpg' to 'photo-ne.jpg' will ensure that the image retains its original dimensions and is not resized during the upload process.
