Same zoom-in detail for fabric and stitching — a fraction of the file size Shopify stores and serves.
You didn't sign up to be a photo editor.
Shopify merchants uploading product photos manually face the same routine every week: a folder of phone photos or photographer proofs, each one 3–12 MB, dragged one at a time into the Shopify admin. Nothing warns you that a 40-photo product launch just added 200 MB of dead weight to your storefront. Shopify doesn't compress images meaningfully on upload — it stores what you give it. Slow product pages mean shoppers bounce before they see your price, and Google's Core Web Vitals score (which affects your SEO ranking) drops with every oversized hero image.
Compress before you upload, not after.
Export your product photos as usual
Straight from your phone, DSLR, or photographer delivery folder — no special export settings needed.
Drop the whole folder into FastCompressor
Batch process 5 or 500 images at once. It runs locally in your browser or desktop app — nothing uploads to a server while you wait.
Export as WebP or optimized JPG
Shopify supports WebP natively. You get the same visual quality your customers already expect, at a fraction of the file size.
Upload the optimized batch to Shopify
Re-check your theme's PageSpeed or Core Web Vitals score. Most stores see the improvement immediately.
The features Shopify merchants actually use.
Batch entire collections
Compress a whole product launch or your entire catalog in one pass instead of one photo at a time.
WebP + JPG export
Export in the formats Shopify's theme engine already knows how to serve responsively.
No file-count limits
Whether it's 12 photos for a new product or 800 for a full seasonal reshoot, there's no batch cap.
Preserves product zoom detail
Quality settings tuned so customers can still zoom in on fabric texture or stitching without seeing artifacts.
Not shown here: TIFF export, RAW support, and other format tools built for photographers and designers — you likely won't need them for product photography.
Speed isn't a nice-to-have. It's a conversion lever.
E-commerce pages that load in under 2 seconds convert at roughly 3.05%, compared to 1.94% for pages loading in 3–4 seconds — a 57% jump in conversion rate from shaving off about a second, according to Portent's analysis of billions of page views. Oversized, uncompressed product photos are one of the most common reasons Shopify storefronts miss that 2-second window.
Stop compressing product photos one at a time.
FastCompressor Pro removes the batch limits, adds automated WebP export presets sized for Shopify themes, and runs as a desktop app so you're not tied to a browser tab.
