Shopify storefront workflow
How to compress images for Shopify
A lightweight product-photo workflow helps Shopify stores protect original assets, reduce upload sizes, and keep collection pages responsive.
Compress an image privatelyUseful for merchants, ecommerce operators, and agencies preparing catalog images for Shopify product and collection pages. PixPact processes images locally in your browser; no image upload is required.
A practical workflow
- Export a working copy of each product photo and keep the master asset outside the storefront.
- Choose WebP or JPEG for product photography; keep PNG for transparent logos, badges, and UI graphics.
- Use the same crop and aspect ratio across a product set, then compare the compressed result at the card and product-page sizes.
- Upload the smaller file to Shopify and add descriptive alt text that explains the product rather than repeating keywords.
Before you publish
- Use consistent product dimensions
- Avoid text baked into photos when possible
- Check zoom quality on the product page
- Recheck mobile collection cards
Common questions
Will Shopify compress images again?
Shopify can create delivery variants, but preparing a sensible source file first still reduces the bytes you upload and manage.
What format should a Shopify product photo use?
WebP or JPEG usually suit photographs. Use PNG when transparency is essential and verify how your theme handles the asset.
