How sellers use this tool
Shops, ads, and print partners disagree on formats. Convert batches between JPG (smallest listings), PNG (transparency), and WebP (modern web) entirely in your browser — useful when a supplier sent mixed HEIC-export leftovers as PNG screenshots.
How to use this tool
- Upload the mixed folder.
- Pick JPG, PNG, or WebP and quality if needed.
- Convert / preview to check file size captions.
- Download the normalized set for your seller center.
For Shopee/Amazon gallery photos, JPG is usually best. Keep PNG when you need Cutout transparency or logo watermarks.
