- Optimization of all photos on the site - galleries, blogs, CMS pages, photos in descriptions

PrestaShop & WebP
WebP is an image compression format developed by Google. WebP with a smaller size up to 85% maintains comparable image quality with the JPEG format. This format is promoted by Google and is increasingly used on the Internet. By using the WebP format you will achieve higher results in Google Page Speed, Lighthouse and GTMetrix.
WebP is supported by the following browsers: Google Chrome, Firefox, Opera, Edge, GNOME Web, Midori, Falkon, Pale Moon and Waterfox. If the client browser does not support the WebP format - the jpeg / png image will be loaded.
For the conversion to WebP to work, any of the following methods must be installed on your server:
- webp (PHP exec() must be enabled)
- imagick (uses Imagick PHP extension)
- gmagick (uses Gmagick PHP extension)
- imagemagick (PHP exec() must be enabled)
- graphicsmagick (PHP exec() must be enabled)
- gd (uses Gd PHP extension)
Convert product images to WebP format
Increase store loading speed by converting photos to WebP format. Optimize product photos, categories images, images in product descriptions and on CMS pages. The conversion will also include images displayed by blog, galleries and any other modules. Reduce the loading time of the store on mobile devices and increase the SEO result!
Install and use
Just install the module and enable WebP format conversions. All photos in your store that you upload in JPEG or PNG will be converted on the fly to the WebP format. Photos existing in your shop will be also converted to WebP! This will save a lot of data, will not load the server and will reduce the loading time of the store to a minimum.
PrestaShop & Lazy Load
Lazy Load is based on a technique that downloads images thats are currently in the browser window. All other images are replaced with the "placeholder image". The target images will be loaded as soon as the user browses them by scrolling the page. This will increase the page speed and reduce data transmission for mobile devices with limited internet or poor coverage.
Lazy Load is SEO friendly
Your images will be visible to web robots. The URL link to photos and images are still in the page source code. Our module has been prepared in accordance with good SEO practices according to Google and will positively influence the results of Google Page Speed, Lighthouse and GTMetrix tests of your PrestaShop store.
Install and use
All you have to do is install the module and choose a replacement effect for loading the images. The module will do the rest for you.

Work good but make sure you have installed one of mentioned extensions on your server if you want to use webp format.
OK
Dziękuję za ustawienie serwera. To on był u nas problemem.
Efekt podobny z 67 na 81. Dobry moduł
great module: webp + 12 point, lazy load + 7 points page speed
Moduł robi co ma robić. Wynik page speed desktop 72 do 81, mobile 44 do 55. Polecam.
Wide Print - najszybsza metoda dla czasu ładowania sklepu to "Load lazily without placeholder". Dla zdjęć i obrazków możesz wybrać jedną z następujących metod:
1. Load normally (ładowanie bez lazyload)
2. Load lazily without placeholder (fastest) (lazyload bez obrazka zastępczego)
3. Load lazily and use original image with low resolution as placeholder (looks nice) (lazyload z powolnym ładowaniem)
4. Load lazily and use shop logo with low resolution as placeholder (compromise between options 2 and 3) (lazyload z obrazkiem-zaślepką)
Po ostatniej aktualizacji można ustawić metodę lazyload dla zdjęć produktów i dla pozostałych zdjęć w sklepie niezależnie. Która metoda jest najlepsza dla tych zdjęć?
Moduł działa po prostu dobrze, dokładniej, strona w trakcie ładowania wygląda ładnie. Dzięki!
