How-to Guide
Create Before-After Product Images for Shopify
Before-and-after visuals are among the highest-converting product images online. They remove doubt, prove the product works, and tell a story in a single frame — which is exactly what Shopify product pages need.
Try MergeFrame — FreeShopify's product image gallery supports up to 250 images per product, but in practice buyers engage most with the first 3–5. A crisp before-and-after grid placed in position 2 or 3 catches attention after the main shot and delivers proof before the buyer scrolls to reviews.
The classic format is a 1×2 horizontal split: the 'before' state on the left, the 'after' on the right. For supplements, skincare, or cleaning products, this can show: dull skin vs. glowing skin, stained fabric vs. clean fabric, cluttered desk vs. organized setup. For physical transformations like fitness equipment, the same layout works vertically (top / bottom).
MergeFrame lets you set a custom gap between panels — even a thin colored line between the two sides acts as a divider and makes the comparison feel intentional rather than accidental. Use the same aspect ratio for both images before uploading for a clean 50/50 split. Shopify's recommended size is 2048×2048px; exporting at that dimension ensures the zoom function is crisp on Retina displays.

Frequently Asked Questions
Should before go left or right?
Convention places 'before' on the left and 'after' on the right — this matches natural reading direction and sets expectations without any labeling.
Do I need to add labels like 'Before' and 'After' to the image?
It helps, especially for ambiguous products. You can add text overlays before importing into MergeFrame, or use a tool like Canva to add labels afterward.
What if my before and after images have different dimensions?
MergeFrame will fit each image into its cell. For a perfect 50/50 split, crop both images to the same dimensions and aspect ratio before uploading.
