One of the most frustrating things about selling online: you have one perfect product photo, but it needs to fit Amazon, Shopify, Etsy, Instagram, Pinterest, TikTok… and every platform wants a different size.
Amazon's main image has to be 1:1 square at 1000×1000. TikTok product cards demand a 3:4 vertical layout. Instagram feed posts shine at 1080×1080, but Stories need 9:16. The old way was opening Photoshop and cropping each one by hand — burn through half a day just resizing.
This guide breaks down the exact image sizes for every major e-commerce platform, plus how to batch-crop everything in seconds.

Why Can't I Use One Image Everywhere?
New sellers often ask: "If I shoot a 1:1 square photo, can't I just use it on every platform?"
Technically yes. Effectively? No — and it'll hurt your sales.
There are three reasons:
Display ratios differ — Amazon's search results show 1:1 squares. TikTok's feed is 3:4 vertical. Instagram's explore page favors 4:5 portraits. A square image in a vertical slot gets awkward letterboxing. It looks amateurish.
Information density varies — An Amazon main image needs to isolate the product on a white background. An Instagram post needs visual storytelling. A Pinterest Pin needs stacked text over the image. One crop doesn't fit all jobs.
Algorithm preference — Every platform's recommendation algorithm favors images that match its native aspect ratio. Full-bleed, correctly cropped images get better reach. Oversized images with black bars? The algorithm pushes them down.
How to Batch-Crop with PixelForge
Open PixelForge's multi-size crop tool and follow these steps:
Step 1: Upload your original image Start with a high-resolution original — ideally 2000×2000px or larger. The higher the source resolution, the sharper your crops will be, even when a platform needs a tight zoom.
Step 2: Select your target platforms The tool comes with built-in presets for Amazon, Shopify, eBay, Etsy, TikTok, Instagram (feed, portrait, Stories), Pinterest, and WhatsApp. Just check the boxes for every platform you sell on.
Step 3: Adjust the crop area Each preset shows a preview overlay. Drag the crop frame to position your product — make sure the main subject stays visible in every aspect ratio. You can fine-tune each crop independently.
Step 4: Export everything Once you're happy with the previews, download them one by one or grab the entire batch as a ZIP file. Done.
Pro Cropping Tips
Center composition — Position your main subject dead center in the original photo. That way, cropping to any aspect ratio keeps the most important content visible. Works for every platform.
Leave headroom — If you plan to sell on Instagram or Pinterest, shoot with extra space above the product. A 1/3 buffer at the top gives you room for text overlays, titles, or branding.
Respect the safe zone — Amazon's main image safe zone is the center 85% of the frame. Keep critical product details, logos, and text out of the outer 15% — they might get cropped off in search results or mobile views.
Maintain a consistent style — Use the same lighting, background, and color grade across all your product photos. Customers scrolling through your store should feel a cohesive brand identity, not a messy collage of random crops.
