Miko Bulk Image Resizer

Miko bulk resizes, compresses and watermarks product images directly where they live in your store. Large product images slow down your site, but resizing them manually means exporting and uploading every file again. This app handles bulk image optimization without the hassle. Choose your size and see a real before and after preview built from your own photos before approving any changes. Every original image is kept for 30 days, so you can undo any run with one click if needed. The built-in image health check finds oversized files, missing alt text and odd image shapes across your catalog. Bulk alt text lets you write SEO-friendly descriptions from a template you preview first. You can also add watermarks, save images as WebP or AVIF formats, and target specific products by collection, tag or vendor. Your image SEO is handled as you optimize.
