Tips for E-Commerce Product Images
For Shopee, Lazada, TikTok Shop, and other e-commerce platforms, product images should follow these guidelines:
- Use square (1:1) aspect ratio: Most marketplaces display product images in a square grid. Use 800×800 or 1024×1024 pixels.
- Keep the main image clean: The primary product photo should have a white or transparent background. Use BersihBG's Remove Background tool first.
- File size under 2MB: Compress images to under 2MB to ensure fast loading on mobile shopping apps.
- Use the correct zoom format: Some platforms support zoom-in on product images. Higher resolution (1200+ px) enables better zoom quality.
