Why Does WhatsApp Compress Images?
WhatsApp compresses images for several important reasons:
- Data Usage: Reduces mobile data consumption for users
- Faster Delivery: Smaller files send and receive faster
- Storage: Saves storage space on devices
- Server Costs: Reduces bandwidth and storage costs for WhatsApp
- User Experience: Ensures messages load quickly even on slow connections
WhatsApp Image Limits
Understanding WhatsApp's compression limits:
- Maximum file size: 16MB (but will be compressed if larger)
- Recommended size: Under 1MB for best quality retention
- Dimensions: Images are resized to max 1600x1600 pixels
- Quality: JPEG quality is reduced to approximately 75-85%

Alternative: Send as Document
For images where quality is critical, you can send them as documents:

- Choose your image
- Images sent as documents are not compressed
- Note: Recipients will see it as a document, not in the chat preview
