Apps merchants weigh against Featherweight, with their own detected stores and ratings.
Compress every store image in one click. Faster pages, rankings, zero broken links.
Most Shopify stores carry unoptimized images — oversized product photos that slow mobile pages, hurt conversions, and tank Core Web Vitals. Featherweight fixes this automatically. Open the app, click Optimise, and every image is compressed using mozjpeg and palette quantization, resized to a 2048px maximum, and EXIF data is stripped. Files are replaced in place — same URL, same product links, nothing breaks.
Every number on this page comes from public storefront scans and the public Shopify App Store listing. If Shoplist shows Featherweight on a store, it is there.
