Batch compress your entire product catalog in one pass.

1
Upload Your Product Images
Drop up to hundreds of product photos into ImageMint at once. Browser-based batch processing keeps everything local.
2
Choose Format & Quality
For product photos, WebP at quality 82 offers the best balance — Shopify serves WebP to modern browsers automatically.
3
Download and Upload to Shopify
Grab the ZIP of compressed images, then upload them in Shopify admin → Products → Media.

Shopify recommends images under 2048×2048 px and ideally under 200KB each for fastest Core Web Vitals scores.
Shopify auto-generates WebP variants from your uploads, but starting from a compressed source still reduces storage and improves speed.
Use consistent dimensions across all products (e.g., 1200×1200 square) for cleaner grid layouts and higher conversion rates.

Does compressing images hurt Shopify SEO?

The opposite. Google uses Core Web Vitals as a ranking signal, and image size is the #1 factor. Smaller images = better ranking.

Should I use PNG or JPEG/WebP for Shopify?

WebP for photos, PNG only if you need transparency (e.g., logos, packshots on white). JPEG is fine if WebP is unavailable.

Do I need a Shopify app for this?

No. ImageMint runs in your browser before upload, so you avoid monthly subscription fees and Shopify performance overhead.
