Why do product image dimensions matter?

Marketplaces reject or downrank listings whose images are too small, badly cropped or on the wrong background. Amazon needs 1600 px or more on the longest side to enable zoom, and zoom-enabled listings convert noticeably better.

Are my images uploaded to a server?

No. Resizing, cropping, background removal and compression all run locally in your browser, so your product photos never leave your device.

Can I optimize several images at once?

Yes. Batch processing is supported and the number of images per batch follows your MagicBG plan. Results can be downloaded individually or as a single ZIP file.

What happens if my photo is too small?

MagicBG warns you instead of upscaling a low-resolution file, because artificial upscaling produces blurry listing images that marketplaces may reject.

What is marketplace image optimization?

Every marketplace publishes its own image specification: a minimum resolution, an expected aspect ratio, a background rule and a maximum file size. Marketplace image optimization takes the photo you shot and rewrites it to those specifications — resized, centered, padded, compressed and exported in the right format — so the listing is accepted the first time and looks consistent across your catalog.

Why product image dimensions matter

• Amazon only enables zoom above 1600 px on the longest side, and zoom lifts conversion.
• Undersized images are downranked or rejected by automated listing checks.
• Inconsistent crops make a catalog look amateur in grid search results.
• Oversized files slow mobile listings down and hurt the buying experience.

How MagicBG optimizes product images

1. Your images are read locally — nothing is uploaded to a server.
2. The marketplace preset sets the canvas size, aspect ratio, format and quality.
3. Optional AI cutout removes the background and places the product on white, a custom colour or transparency.
4. The product is centered with the right padding, using fit or fill.
5. The export re-encodes the image, dropping camera metadata and compressing it.
