How do I make my Squarespace site faster?

Image optimization is the single biggest factor in Squarespace site speed. Squarespace automatically serves responsive images, but it cannot fix oversized source files. Before uploading, resize images to a maximum of 2500 pixels on the longest side and compress them using a tool like TinyPNG or Squoosh. Keep file sizes under 500 KB for full-width images and under 200 KB for smaller photos. Avoid uploading images straight from your camera — a 6 MB photo will slow your page dramatically even after Squarespace resizes it.

Reduce third-party scripts and embeds. Every external script — Google Analytics, Facebook Pixel, chat widgets, Instagram feeds, YouTube embeds — adds to your page load time. Audit your code injection and remove any scripts you are not actively using. Limit embedded content to one or two items per page, and use lazy loading for videos and maps. If you have a chat widget, consider whether it is actually generating conversations or just slowing down your site for everyone.

Clean up unused pages, blocks, and content. Squarespace loads CSS and JavaScript for all block types used across your site, even on pages that do not use them. Remove any draft pages, unused gallery blocks, and experimental sections that you created during design but never published. Simplify your navigation structure and reduce the number of pages that load on initial visit. A lean, focused site loads faster and converts better.
