Naumio CropCheck Pro — Offline Batch Crop & Export Tool

Correct a whole product-image batch before you list it.

Naumio CropCheck Pro is an offline browser tool for sellers who need the same product images framed consistently across listing and sharing surfaces.

Add up to 20 PNG, JPEG, or WebP images. For each image, choose Fit or Cover, move the focal point, adjust zoom, and inspect the crop. Export all included frames—or the selected frame—in one ZIP created locally in your browser.

INCLUDED FRAMES

• Etsy portrait preview — 2000 × 2500 PNG

• Shopify square — 2048 × 2048 PNG

• Marketplace 4:3 — 2000 × 1500 PNG

• Share 16:9 — 1920 × 1080 PNG

• Selected custom size — 64 to 5000 px per side

DELIVERED FILES

• CropCheck-Pro.html — self-contained offline app

• START_HERE.txt — setup, workflow, privacy, and limitation notes

• LICENSE.txt — personal or one-small-business license

PRIVACY AND COMPATIBILITY

Image processing and ZIP creation happen locally in your current browser window. No account, image upload, backend, analytics, or cloud-storage feature. Version 1.0 is tested in desktop Chrome/Chromium browsers. Responsive layout does not mean local-file opening or ZIP delivery has been verified on iOS or Android.

IMPORTANT LIMITS

CropCheck corrects image geometry. It does not edit the underlying product, remove backgrounds, generate images, decide which object matters most, or promise marketplace acceptance, reach, or sales. Inspect the provider’s final listing preview. You are responsible for having the rights to every source image you load.

Desktop-browser tested. Digital download only. Nothing is shipped. No account or image upload. No marketplace-acceptance or sales promise.
