 * To my understanding, your plugin will optimize images in the media library and
   replace them with a smaller file.
 * However, in the following image:

   =537%2C100&ssl=1)
 * After I clicking “Download File”, the downloaded file size is 76kb, neither the
   new file size, nor the original file size.
 * Why?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fwhat-does-your-optimization-actually-does%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hi [@chcw](https://wordpress.org/support/users/chcw/)
 * Thank you for contacting us!
 * When you are converting your images in WebP and check on your Media Library(List
   View) the “New Filesize” corresponds to the size of the WebP version of your 
   image. In order to display the WebP version of the image on your website you 
   will have to enable the display WebP option through Settings > Imagify. If you
   do not enable the display WebP option then the image will be displayed in its
   optimized version.
 * On the downloaded image you mentioned above you have the optimized version of
   the image as the “New Filesize” is the Webp version size.
 * Let me know if you need further assistance. I’ll be happy to help.
 * Best Regards,
 * Ioanna

 * Hi,
 * In my settings, I enable “**Create WebP versions of images**” but disable “**
   Display images in WebP format on the site**“, since we are using Cloudflare which
   can also deliver the image as webp format.
 * So, to my understanding, the new file size(102kb) is for the .webp format? And
   when I download the file, it is in .jpg format(71.6kb), smaller than the .webp
   file? Are the downloaded file(.jpg) the optimized one? Are the jpg and webp both
   saved in the system?

 * Hi [@chcw](https://wordpress.org/support/users/chcw/)
 * Yes, the “New FIlesize” applies to the WebP size if you are creating WebP images.
   Unfortunately, I am not able to see your screenshot as it is really small. However,
   the WebP size should not be bigger than the optimized size. Is it possible to
   share the original version of the image in question to test it from our end?
 * The JPG and the WebP version of your images are saved on your server at wp-content/
   uploads/. If the original format image is located at wp-content/uploads/2020/
   02/image.jpg, then its WebP version will be at wp-content/uploads/2020/02/image.
   jpg.**webp**

 * I don’t know why the uploaded image became so small. You can see this one: [https://www.datanumen.com/temp/images/2023-05-16_6-28-55.jpg](https://www.datanumen.com/temp/images/2023-05-16_6-28-55.jpg)
 * By the way, how to get the original version of the image?

 * Hi [@chcw](https://wordpress.org/support/users/chcw/)
 * Thank you for the screenshot.
 * The original image size should be 177KB and if you have saved the backup version
   of the image before optimizing it you should be able to find it in the following
   location on your server wp-content/uploads/backup/2023/05 or send here directly
   the image URL from your website.

 * Hi, [@wp_media](https://wordpress.org/support/users/wp_media/)
 * OK. Here you are: [https://www.datanumen.com/wp-content/uploads/backup/2023/05/the-archival-processing-tool-user-guide-p90.jpg](https://www.datanumen.com/wp-content/uploads/backup/2023/05/the-archival-processing-tool-user-guide-p90.jpg)

 * Hi [@chcw](https://wordpress.org/support/users/chcw/)
 * Thank you for sharing the original image and indeed I was able to reproduce the
   issue. In this case, at the moment you can install and activate [this helper plugin](https://github.com/wp-media/imagify-helpers/raw/master/webp/imagify-prevent-larger-webp/imagify-prevent-larger-webp.zip)
   which will not create the WebP version of an image if it will be bigger, can 
   you please check this on your end?
 * Feel free to let me know how it goes.

 * OK. That’s fine. Since we only use JPEG version, that does not have a problem.
