Best File Formats for Shopify Images
Here’s a quick comparison of commonly used file types:
| File Type | Best Use | Advantages | Disadvantages |
| JPEG | Product photos, banners | Small size, good quality | Slight quality loss |
| PNG | Logos, transparent backgrounds | High quality, transparency | Larger file size |
| SVG | Logos, icons | Scales perfectly, tiny file | Not for detailed images |
| WebP | Almost everything | Excellent compression | Limited older browser support |
| GIF | Simple animations | Animations, loop support | Poor color range, large |
If your theme and browser support it, use WebP—it can reduce file sizes by up to 30% without losing visible quality.

How to Check Image Size in Your Store
Not sure if your image is too small or too large? Here’s how to check:
- Right-click the image in your browser and select “Inspect”.
- Hover over the image to see the rendered size.
- Compare that with the actual image dimensions.
If your actual image size is smaller than what your theme is displaying, it might appear blurry. In that case, upload a higher-resolution version.
Common Image Mistakes Shopify Merchants Make
| Mistake | Impact | How to Fix |
| Uploading huge images | Slower page speed | Compress and resize before upload |
| Inconsistent aspect ratios | Weird cropping or layout breaks | Use same aspect ratio across products |
| Poor mobile optimization | Bad user experience | Use responsive sizes and test on mobile |
| Missing alt text | SEO and accessibility issues | Always add descriptive alt tags |
| Low-resolution logos | Looks unprofessional | Use SVG or high-res PNG |
Advanced Tips to Maximize Impact
- Use lifestyle photos in product galleries to increase emotional connection and conversion.
- Compress all images before uploading to improve load times.
- Use square images (1:1) for products and 16:9 for banners and hero sections.
- Keep file names descriptive, like red-silk-dress-front.jpg, for better SEO.
- A/B test banners and hero images to see what converts best.
