Fit: keep the full frame
Fit scales the full decoded source frame inside the target canvas. If the aspect ratios differ, padding can appear. Fit does not expand the image with AI or choose a product-aware crop position.

Prepare a batch
Marketplace presets prepare technical output. They do not certify marketplace compliance or guarantee moderation approval.
- Add up to 200 supported product images.
- Choose Amazon Main, Etsy Listing, eBay Listing, Shopify Product or Custom.
- Choose Fit or Fill and a supported output format or background setting.
- Process the batch and review the preview, warnings and per-file statuses.
- Export successfully processed outputs as one ZIP.
Fit and Fill
Fill: cover the canvas
Fill covers the target canvas and crops excess source area from the center when aspect ratios differ. Source edges can be cropped. Fill does not detect the product, face or semantic center.
Marketplace preset boundaries
Amazon Main
Amazon Main is scoped to the main-image preset, not every Amazon image role. The 2000×2000 canvas is a Logrun Lab recommendation for this preset. Review the final image and current Amazon rules before upload; the preset does not guarantee approval.
Etsy Listing
2500×2000 is a Logrun Lab recommendation, not an Etsy requirement. This preset offers JPEG and PNG output. Transparent output is unavailable. Output over 1 MB can still be exported; the tool shows an upload-reliability warning rather than blocking export.
eBay Listing
eBay recommends 1600×1600 for listing photos and requires at least 500 px on the longest side. This preset offers JPEG, PNG and WebP and enforces the current 12,000,000-byte uploader ceiling. Fit can add padding that looks border-like, so review the result against current eBay content rules before upload.
Shopify Product
Shopify recommends 2048×2048 for square product images. This preset offers JPEG, PNG and WebP. Output must stay below 20,000,000 bytes. The separate platform maximum is 5000×5000 or 25 MP. Final storefront appearance can depend on the theme and image delivery.
Custom
Set the canvas, Fit or Fill, supported output format, background and quality for the current batch. Custom settings are user-defined output settings and do not represent any marketplace's rules.

Formats, limits and browser processing
Input supports JPG/JPEG, PNG and WebP, with up to 200 files per batch. Output choices depend on the selected preset and current browser support.
Image processing happens in the browser. Logrun Lab does not store image contents. Runtime and success can depend on source dimensions, chosen settings and browser/device resources. The ZIP contains successfully processed outputs only.
