Fernpix: Check if a listing photo will pass — 100% on-device.

Fernpix is a local-first image toolkit for marketplace sellers and anyone fighting upload limits. Drop a Shopee / Lazada / TikTok Shop main image into Will It Pass? — Fernpix checks 1:1, white background, file size, and format in the browser, then fixes what it can. Nothing is uploaded. Your unreleased SKUs never leave the device. Free checks stay free. Pro batch-repairs a catalog and ZIP-exports. Also: compress, HEIC→JPG, ID photos, product cutout, and photo restore — all on-device.

I kept seeing Shopee / Lazada sellers get listing photos rejected for boring reasons: not square, not white enough, too heavy, or iPhone HEIC. Cloud editors mean uploading a whole catalog. Fernpix runs the check and the fix in your browser. If you sell on MY marketplaces, try Will It Pass? with one main image and tell me which rule still bites you.

We narrowed Fernpix around one seller job: catch product-photo problems before a marketplace upload fails.

You can now start with a general marketplace preflight or use a dedicated Amazon, Shopee, Lazada, or TikTok Shop profile. It checks dimensions, format, file weight, background, product fill, centering, and crop risk; supported fixes stay in the browser, and product originals are not uploaded to Fernpix.

This is an independent preflight—not an approval guarantee—and recommendation checks are separated from platform rules.

I would value one specific piece of seller feedback: after checking a real listing photo, was the failure reason clear enough to act on?
