Miko Bulk Image Resizer

Bulk resize, compress and watermark product images. See the real before and after first.

Large product images slow a store down, and resizing them by hand means exporting every file and uploading it again. Miko bulk resizes, compresses and watermarks product and collection images where they already live. Choose a size, see a real before and after built from your own photos, and approve it before anything changes. Every original is kept 30 days so any run can be undone. Bulk alt text and an image health check are built in, so your image SEO is handled as you go.

• See a real before and after of your own images before anything is changed
• Every original kept for 30 days, so any run can be undone in one click
• Bulk alt text from a template you preview, written across your catalogue
• Image health check finds oversized files, missing alt text and odd shapes
• Watermark, save as WebP or AVIF, and target by collection, tag or vendor
