WhatsApp Business's catalog feature displays product photos in a roughly square thumbnail grid, and a photo that was not prepared with that shape in mind can end up cropped in an unflattering or confusing way — a product cut off at the edges, or the most important part of the image pushed out of frame. A little preparation before uploading avoids this entirely.
Steps
- Photograph or select your product photo, keeping the product centred with some margin around it.
- Crop the image to a square (1:1) aspect ratio, centring the product within that square.
- Resize to a reasonable, consistent pixel size across your whole catalog — roughly 1000 × 1000 pixels is a safe, commonly used target.
- Compress with the Image Compressor to keep the file reasonably light for fast loading in the app.
Why the square crop matters specifically here
If you upload a photo in its original rectangular shape, the catalog display will crop it to fit the square thumbnail automatically, and that automatic crop does not know which part of your image is the important part — it may cut off the top of a product, or crop tightly into one corner. Cropping the image to a square yourself, with the product deliberately centred, ensures the display shows exactly what you intended rather than leaving it to an automatic crop.
If you have already removed the background from the product
A product cutout with a transparent or plain background, following the approach in our guide to removing the background from a product photo, works well for a catalog image once placed onto a plain square canvas — centre the product within the square with reasonably even margin on all sides, rather than filling the frame edge to edge, which gives a more polished, consistent look across your catalog.
Keeping every product photo in the catalog visually consistent
- Use the same square dimensions for every product image, not a mix of different sizes.
- Keep a consistent amount of margin around each product within its square, rather than some products filling the frame and others floating in a lot of empty space.
- Use a consistent background — plain white or a single brand colour — across the whole catalog for a cohesive, professional look.
Balancing quality against loading speed in a chat app context
A WhatsApp catalog is typically browsed on mobile, often over a variable mobile connection, so keeping each image reasonably light matters more than it might for a desktop-browsed website. A well-compressed image in the range of 100–300 KB is usually a good balance, sharp enough to look professional while loading quickly even on a slower connection.
Preparing a whole catalogue's worth of images efficiently
If you are setting up or refreshing a catalog with many products, process the photos in a consistent batch — crop each to the same square proportions, resize to the same pixel dimensions, and compress with the same setting — rather than treating each product image as its own separate task with potentially inconsistent results. This is the same batching principle covered in our guide to preparing product photos for marketplace listings, applied here to a chat-based catalog instead.
Updating a product photo later without disrupting the rest of the catalog
If you need to update just one product's photo later, apply the exact same crop, resize and compression settings you used for the rest of the catalog, so the updated image fits in visually with everything else rather than standing out as differently prepared. Keeping a written note of your standard settings makes this consistency easy to maintain over time, even months after the original catalog was set up.
Deciding whether to show the product alone or in context
A plain product shot, isolated against its background, works well as the primary catalog image, but a second image showing the product in use or in context (worn, assembled, in a real setting) often helps a buyer understand scale and appearance better than an isolated shot alone. If your catalog supports multiple images per product, consider pairing a clean isolated shot with one contextual photo, applying the same square-crop and sizing approach to both for visual consistency.
Frequently asked questions
Does WhatsApp Business require an exact pixel size?
There is no single strict requirement, but a square aspect ratio at a reasonable resolution (around 1000x1000 pixels) is a safe, widely used approach that displays well.
What if my product does not fit well into a square crop?
Add margin around the product within the square rather than cropping tightly, so the product remains fully visible and well-framed.
Should catalog images have a transparent or a solid background?
A solid, consistent background (plain white is a safe default) generally looks cleaner in a catalog grid than a transparent one, which can display inconsistently depending on the surrounding interface.
Can I use the same photo for both my website and my WhatsApp catalog?
Yes, though you may want to crop separately for each, since your website may use a different aspect ratio than the catalog's square format.
How many products can I prepare this way at once?
There is no practical limit; process them in a consistent batch for the most efficient and visually coherent result.
Does image quality affect how customers perceive my catalog?
Yes, consistent, well-cropped, professional-looking images build more buyer confidence than inconsistent or awkwardly cropped ones.
Is the tool free and private?
Yes. No sign-up, no watermark, and files are removed from the server automatically about an hour after processing.
