This practical guide separates useful editorial practices from hard platform requirements. Check the current rules of your destination store before publishing.

Is there one required image size?

No. Online stores use different aspect ratios for listing cards, galleries and mobile experiences. Inspect the display slots in your theme and keep a sufficiently detailed source file for future exports.

Square versus portrait crops

A square 1:1 crop is common in product grids. A portrait 4:5 crop can show more of a full outfit when presenting model-on clothing. Neither ratio is a universal ranking requirement; check how your theme crops products on mobile.

WebP, JPEG or PNG?

JPEG is common for photographs. WebP can preserve useful detail at an efficient file size. PNG may be appropriate for graphics or images requiring transparency. Choose based on image content and platform support rather than treating any format as mandatory.

Balance sharpness and speed

Large images can slow loading, but excessive compression can destroy fabric texture, labels and stitching details. Review actual mobile output and use responsive images sized for the rendered display area.

Image search fundamentals

Write descriptive alt text, use clear filenames and place images on crawlable product pages. Google's image SEO guidance describes how nearby text and image quality help provide context.

A useful five-view checklist

For a garment, a main view, model-on shot, fabric close-up, side angle and care label can answer different customer questions. Five images is a practical editorial example, not a Google Shopping eligibility rule.
