FAQ
Will compression make product photos look worse?
The listing centers on lossless compression to WebP: the goal is smaller files without a soft, over-compressed look. Keep originals backed up (the app supports restorable backups) and spot-check hero SKUs after the first batch.
How is this different from DEVDIY: AI SEO & GEO Tools?
AI SEO & GEO Tools focuses on blogs, product copy, and GEO-minded structure. SEO Speed Image focuses on image weight, alt/meta at scale, Core Web Vitals helpers, and 404→301 cleanup. Many stores use both.
Is there a free plan?
Yes. The Shopify App Store listing includes a free plan and a free trial.
