      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.

      Convert product photos to WebP format

      Our module will optimize all graphics in your store. This will have a positive effect on the loading speed, server performance, results in performance tests and user experience while surfing your store.

      We used (2021) latest available technologies to optimize photos for the internet browsers. Our module will save a huge amount of data, will not overload your server and will shorten the load time on mobile devices and computers.

      The module converts to WebP all photos in your store:

      • Product photos, photos on product lists and product descriptions
      • Pictures on CMS pages, home page, contact page, etc.
      • Photos displayed by external modules such as blogs, albums and galleries, banners and sliders.

      Module will start generating graphics in the WebP format in the background when they are first loaded by your customers' browsers. Thanks to this, the module does not overload server with long-term operations in the process of generating WebP and during their future use.

      1. All new photos you upload in JPEG or PNG will be converted to WebP on the fly.
      2. All photos already in your store will be converted to WebP on they first load.

      The module detects newly added products, changes in products photos and deletion of photos and takes care of order in the graphics files on the server. 

      PrestaShop & Lazy Load

      To shorten the time to full interactivity of the webstore, you can turn on the Lazy Load function. This ensures that all key photos and images will be loaded first, and then images outside of the visible screen. The images will not be loaded until the user starts scrolling the page. Thanks to this, you will increase the speed to full interactivity and reduce data transmission for mobile devices with an internet limit or a slow connection.

      Thanks to Lazy Load, the server will not load items that customer will not want to see, and this will directly affect the store's performance and the speed of its loading.

      • While loading, the image storage objects keep their original size
      • The module does not generate page jumps while it is loading

Our module has been prepared in accordance with good SEO practices according to Google guidelines, thanks to which it actually speeds up the operation of the store and relieves the server.

      1. Tak, moduł działa z Multistore. Teraz jest to w standardzie, jednak z nowym rokiem obsługa Multistore będzie dodatkowo płatna.
      2. Tak, będzie działał z LiteSpeed, jeśli jest obsługa .htaccess
      3. Tak, patrz pkt. 1.
      4. Moduł dotychczas był zgodny z wszystkimi szablonami, a jeśli pojawiłby się problemy - pomożemy na HelpDesk. Staramy się, aby moduł był maksymalnie uniwersalny :-)

      Dzień dobry,

      dwóch moich klientów jest zainteresowanych uruchomieniem WebP w sklepach proszę o informację w zakresie modułu:
      PrestaShop WebP & Lazy Load - optymalizacja obrazków i zdjęć

      1, Czy moduł jest zgodny z multisore?

      2. Czy będzie działał z serwerem LiteSpeed?

      3. Czy w przypadku jednego sklepu z kilkoma domenami obowiązuje ta sama cena (multistore)

      4. Czy istnieje możliwość przetestowania na sklepie (wersja demo) lub ewentualnie zwrotu do 14 dni (chodzi o zgodność z serwerem/szablonem/modułami)?

      Bardzo proszę o odpowiedź.

      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)

      2019-08-09 Wide Print

      Po ostatniej aktualizacji można ustawić metodę lazyload dla zdjęć produktów i dla pozostałych zdjęć w sklepie niezależnie. Która metoda jest najlepsza dla tych zdjęć?

      2019-07-19 Anna Snopek

      Moduł działa po prostu dobrze, dokładniej, strona w trakcie ładowania wygląda ładnie. Dzięki!
