One of the biggest culprits behind poor performance is undoubtedly image file size, especially on ecommerce platforms, where product visuals are vital. This is where [Squoosh.app](https://squoosh.app/) stands out as a free, strategic tool developed by Google for optimizing images without any perceptible loss of quality. ### What is Squoosh? Squoosh is a web-based image compression application that lets you dramatically reduce file sizes while maintaining visual quality. It runs in your browser, so there’s no need to install anything, and supports several modern formats such as AVIF, WebP, and MozJPEG, which are ideal for delivering highly compressed images. ### Why is image optimization so important? - **Loading performance:** The lighter the website, the faster it loads. This reduces wait times and improves Core Web Vitals, which are essential for SEO. - **Conversions:** Slow pages negatively affect the user experience. Studies show that a one-second delay in loading can reduce conversion rates by up to 7%. - **Technical SEO:** Google values fast websites and penalizes pages that are heavy and provide a poor experience. Image optimization directly contributes to search rankings. - **Bandwidth and storage savings:** Particularly relevant for ecommerce stores with large product catalogs, optimized images reduce CDN and hosting costs. ### How can you use Squoosh.app in practice? 1. **Upload the original image:** Users can drag and drop the image directly into the interface. 2. **Choose an output format:** You can compare formats such as WebP, AVIF, or compressed JPEG side by side. 3. **Adjust the compression level:** See the impact of compression on visual quality in real time. 4. **Download the optimized version:** The final file can be used directly in your CMS or project repository. ### When should you use it? - Before uploading images to a CMS such as WordPress, Magento, or Shopify. - When redesigning websites to improve speed. - As a standard step when uploading catalogs, banners, and digital communications materials. ## Read also Digital ecosystem ### [VitaminaWeb and AnaMid support Projeto Abraço Atípico: technology, sports and social inclusion](https://vitaminaweb.digital/en/blog/vitaminaweb-and-anamid-support-projeto-abraco-atipico-technology-sports-and-social-inclusion) Projeto Abraço Atípico brings together inclusion, sports and support for atypical families, with backing from VitaminaWeb and AnaMid. 21 Sep, 2025 · 6 min Digital ecosystem ### [Creativity, human talent and digital maturity on the agenda at Expointer 2025](https://vitaminaweb.digital/en/blog/creativity-human-talent-and-digital-maturity-on-the-agenda-at-expointer-2025) Rodrigo Neves, CEO of VitaminaWeb and President of AnaMid, took part in the ABMRA Communication Forum 2025, held on September 2 at Expointer (RS)... 03 Sep, 2025 · 3 min Digital ecosystem ### [Website development takes center stage among Brazil’s most contracted digital services](https://vitaminaweb.digital/en/blog/website-development-takes-center-stage-among-brazils-most-contracted-digital-services) Website development is growing and becoming a priority for businesses, according to an AnaMid survey featured by Valor Econômico. 07 Aug, 2025 · 4 min
