How to speed up image loading in Drupal8?

Question

Drupal

Tell me, is there an option to speed up the download of photos for Drupal8?
Image processing in /admin/config/media/image-toolkit is set to "GD2 for image processing"
Can speed be greatly affected by having an Image Style I created? There is a setting for the original image dimensions, i.e. without resizing.
The fact is that large photos (about 6 MB) are being uploaded through the form. It takes a few minutes from a mobile phone, about 30 seconds from a computer. One would think on the mobile Internet, but in applications, photos are loaded relatively quickly.

Answer 1

Answer 2
