A customer asking about a product may need something more specific than an attractive overall image. They might want to see the colour, a connector, a size label, the condition of a used item, or what is included in a box. Choose the source photograph that answers that question before reducing its size. A clear close-up can be more useful than a large but distant product view.
This page starts with our chat-photo preset: fit within 1600×1600 pixels, keep proportions, and export within a 1 MB cap. Those are our sharing settings, not a specification for a WhatsApp Business catalog or every commerce surface. If you are adding a catalog item, check the actual editor and its current instructions separately.
Keep the product accurate. Remove distractions or correct lighting in your own editor, but do not rely on compression to repair glare or reveal a hidden model number. The tool cannot remove a background, change a colour, or create a clean product render. Use a focused original photo with the relevant parts visible, and keep the unedited or edited master for future questions.
