 * Hi,
 * I use your gallery for presentation of high resolution, high quality astrophotography
   images:
 * **Total size: 229.01 MB**: Heavy images negatively affect your website loading
   time and user experience. Optimize images to get better performance.
 * What will happen, when I click on “Optimize Now”. I don’t want all images to 
   be downsampled, only compressed without visible quality loss!

 * Hi [@radinkel](https://wordpress.org/support/users/radinkel/), Nik from 10Web
   here — thanks for your question!
 * When you click “Optimise Now”, the images are compressed in a way that keeps 
   quality loss to a minimum — there’s no downsampling, and the goal is to keep 
   them looking the same.
 * However, since the process is **irreversible**, we **strongly recommend** backing
   up your site or the original images beforehand, just to be safe.
 * Let me know how it goes!
