2200×2200 JPEG · square
Marketplace listings rank partly on image quality: pixel-sharp, correctly-sized photos surface above cropped or low-resolution competitors. Walmart Product Image matches the platform's published image requirement so listings render without the platform's own downscaler kicking in. The preset produces 2200×2200 JPEG, which is what Walmart uses for the primary product image.

How Walmart Marketplace ranks images: search relevance + buy-box optimisation weigh image quality. Posting at the platform's exact native dimensions (2200×2200 px) preserves your original framing and avoids the softening that happens when the platform's own resampler runs to fit its expected size.
Platform-specific note: Walmart Marketplace requires images to be at least 1500×1500 px and to have white backgrounds for the primary image.
This preset is a deterministic recipe — every step has fixed parameters so the result is byte-identical across runs of the same input.
Walmart Product Image crops your input to 1:1 and resizes it to 2200×2200 px as JPEG — a 4.8-megapixel output. The work runs through canvas APIs and a WebAssembly image-encoder; the source image is decoded into an off-screen canvas, transformed in place, and re-encoded without any network upload.
Marketplace listing tools sometimes silently downsample images that exceed their internal limit; this preset's exact-size output sidesteps that path. The browser-side path also means the file never leaves your device — relevant when the input contains personally identifiable information, screenshots of private documents, ID scans, or proprietary product photography.
2200×2200 px, saved as JPEG at quality 92%.
The marketplace this preset targets uses 1:1 framing. For passport photos this matches the printed-photo standard; for social posts it's the safe ratio that fills the feed without horizontal cropping.
The target accepts JPEG, and JPEG compresses photographic content 5-10× smaller than PNG with no visible difference at quality 92%. PNG is the right choice only when the image has hard edges or transparency — which photo-ID, social posts, and product photos don't.
No. This preset runs entirely in your browser using WebAssembly + canvas APIs — no server round-trip. You can verify this in your browser's network panel: only static asset requests, no image upload. The file never leaves your device.
