SquareOptimizer

Compress and replace page images on your own Squarespace site, in place, from your logged-in editor session.

SquareOptimizer | Squarespace Image Optimizer is the only browser extension that compresses images already on your Squarespace site, directly inside your Squarespace editor, without downloading or re-uploading a single file. HOW IT WORKS 1. Open your Squarespace editor and click the SquareOptimizer icon in your browser toolbar. 2. Hit Scan. The extension reads your entire Squarespace Asset Library and cross-references every image against your live pages, showing you which images are used on the site and which are sitting unused in your library. 3. Set your target file size. 250 KB is recommended by Squarespace SEO experts. 4. Select all images or choose specific ones using two filters: filter by size status to see only images that need optimization, and filter by usage to see only images placed on the site or only unused assets in your library. 5. Hit Optimize once. Every selected image is compressed and replaced in place automatically. Nothing on your pages moves. After optimization, the compressed version replaces the original on every page it appeared on. Your original file stays safe in the Asset Library until you choose to delete it. One-click revert restores the original to your pages instantly if you are not happy with the result. WHY SQUARESPACE OPTIMIZER IS DIFFERENT Most Squarespace image optimization advice tells you to compress before uploading. That does nothing for the hundreds of images already live on your site, uploaded from a phone or stock site at 4 to 8 MB each. SquareOptimizer fixes those images. In one session. Without touching your page layouts. No other Squarespace image optimizer compresses existing uploaded images without requiring you to manually re-upload each one. That is the entire point of it.
