TL;DR:<\/strong> Many slow Squarespace websites are affected by image-related issues rather than the platform itself. Common mistakes such as oversized uploads, excessive galleries, poor image compression, and incorrect image sizing can increase page weight and hurt user experience. This article explains the most common Squarespace image mistakes and how they impact website performance, helping you identify opportunities to improve speed without changing your design.\n<\/p><\/div>\n\n\n

Squarespace handles many image optimization tasks automatically, but that doesn’t mean every image uploaded to the platform is performance-friendly. Oversized photos, large background images, image-heavy galleries, and other common Squarespace image mistakes can still create a noticeably slower browsing experience. <\/p>\n\n
