Which image attribute is most critical for reducing page load times without sacrificing visual appeal on Temu?

File size is the most critical image attribute. Reducing file size directly minimizes the amount of data that needs to be transferred to the user's browser, leading to faster page load times. While resolution and dimensions also play a role, file size has the most immediate and significant impact. Using efficient compression techniques, such as optimizing images with tools like TinyPNG or ImageOptim, and selecting appropriate file formats (WebP offers superior compression compared to JPEG) allows for significant reductions in file size without noticeable degradation in visual quality. For instance, an unoptimized 2MB JPEG image can often be reduced to 200KB using WebP without any visible loss of detail. Prioritizing file size ensures that product images load quickly, improving user experience and positively impacting search ranking.
