← ylishi.toolsKey fact: Amazon listing images are a compliance problem before they are a design problem: the main image has to sit on a pure white background, and the file has to carry enough resolution for zoom to be enabled at all. The free batch processor resizes, compresses and converts product photos in bulk, so a whole catalogue can be brought into line in one pass instead of one image at a time.
The main image must be on a pure white background (RGB 255,255,255), show only the product, fill at least 85% of the frame, and be at least 1000px on the longest side (1600px+ recommended for zoom). No logos, watermarks, badges, or extra text. Non-compliant main images can be suppressed by Amazon.
Upload 2000px or larger on the longest side in JPEG (sRGB). Larger images enable the zoom feature, which measurably improves conversion. Keep file sizes reasonable — under 1MB per image — by exporting at quality 80-90 instead of shrinking dimensions.
The tool detects the product silhouette and removes the background automatically, then fills it with pure white so the result passes Amazon's main-image rule. Complex edges (fur, glass, jewelry) may need a manual touch-up pass; always zoom to 100% and check the edges before uploading.
Yes, and you should — but note the different rules: Temu and TikTok Shop accept lifestyle backgrounds and promotional overlays on the main image, so you can reuse your enhanced images there while keeping the Amazon main image clean. Export platform-specific variants from the same master file to stay consistent.
JPEG compression is lossy, but at quality 80-90 the visual difference is negligible while the file size drops 60-80%. The tool optimizes automatically and shows the before/after file size. Avoid re-compressing an already compressed image repeatedly — always work from the original.
