Taobao (淘宝) Image Requirements Deep Dive🔗

E-commerce Platform Requirements

Main Product Images🔗

Taobao's algorithm favors perfectly formatted images:

const taobaoMainImage = {
  dimensions: '800×800px',
  format: 'JPG',
  background: 'Pure white (#FFFFFF)',
  fileSize: '< 3MB',
  quality: '85-95%',
  productFill: '70-80% of frame'
};

Gallery Images Strategy🔗

Maximize click-through rates with proper gallery formatting:

First Image: Clean product shot (800×800)
Second Image: Lifestyle/usage scene
Third-Fifth: Multiple angles
Sixth: Size chart or specifications

Detail Page Images🔗

Long-form content that converts:

Width: 790px (desktop) / 620px (mobile)
Height: Unlimited (recommend < 15000px)
Include: Features, comparisons, certificates

JD.com (京东) Image Optimization🔗

Premium Positioning Requirements🔗

JD.com targets premium buyers with stricter standards:

const jdImageSpecs = {
  mainImage: {
    size: '800×800px minimum',
    preferred: '1200×1200px',
    zoom: '2400×2400px for zoom feature'
  },
  whiteSpace: {
    top: '10%',
    bottom: '10%',
    sides: '5% minimum'
  },
  restrictions: {
    noWatermarks: true,
    noText: true,
    noBorders: true
  }
};

Mobile Optimization🔗

JD's mobile app requires special attention:

Thumbnail: 350×350px
List view: 750×750px
Detail hero: 750×1000px
Pinch zoom: 2400×2400px

Pinduoduo (拼多多) Visual Strategy🔗

Group Buying Focus🔗

Pinduoduo's unique group-buying model needs specific visuals:

const pinduoduoStrategy = {
  heroImage: {
    dimensions: '750×352px',
    purpose: 'Carousel banner',
    style: 'Value-focused messaging'
  },
  squareFormat: {
    dimensions: '750×750px',
    grid: '3×3 product grid',
    emphasis: 'Price and discount'
  }
};

Images must work in social contexts:

WeChat sharing: 500×400px
Mini-program: 345×345px
Group chat preview: 150×150px

Batch Processing with 9 Preset Positions🔗

Our Smart Cropping System🔗

const presetPositions = {
  1: 'Top-Left',      // Logo/brand emphasis
  2: 'Top-Center',    // Headline products
  3: 'Top-Right',     // Sale badges
  4: 'Center-Left',   // Feature focus
  5: 'Center',        // Perfect centering
  6: 'Center-Right',  // Action shots
  7: 'Bottom-Left',   // Base/foundation
  8: 'Bottom-Center', // Grounding shots
  9: 'Bottom-Right'   // Detail corners
};

Intelligent Auto-Detection🔗

Our tool automatically:

White Border Removal Technology🔗

The White Border Problem🔗

Many product photos have inconsistent white borders:

Scanner artifacts
Uneven backgrounds
Photo booth edges
Processing remnants

Automatic Border Detection🔗

def detect_white_borders(image):
    # Analyze edge pixels
    borders = analyze_edges(image)
    
    # Calculate trim boundaries
    trim_box = calculate_trim(borders, threshold=250)
    
    # Preserve product with padding
    final_box = add_padding(trim_box, percent=5)
    
    return crop_image(image, final_box)

Platform-Specific Cropping Workflows🔗

Workflow 1: New Product Launch🔗

Preparing images for multi-platform launch:
