JPG is still the safest marketplace default
Seller portals and upload forms are much more likely to accept JPG without surprises.

How to get product images ready for seller portals
Marketplace image workflows usually fail on the basics: wrong source format, oversized files, inconsistent backgrounds, or a portal that quietly expects JPG.
The fastest path is to treat marketplace prep as a publishing task, not a photography task. You need the accepted format, a reasonable file size, and a clean product presentation.
Use this topic when you are preparing product photos from phones, suppliers, design teams, or mixed asset folders for a portal that needs reliable uploads.
Core decisions
These are the checks that matter most before you touch export settings or start trial-and-error converting.
HEIC is a common hidden blocker
Phone photos may look fine locally but still fail once they hit the listing form.
Transparent assets are a separate workflow
If the product image needs transparency, PNG or WebP may still be relevant for supporting assets.
Consistency beats ad hoc fixes
A marketplace team benefits more from a repeatable prep workflow than from manual one-off corrections.
Recommended workflow
Use this sequence when you want the fastest path to a working result without redoing the task later.
- 1Separate source files into phone photos, supplier photos, transparent cutouts, and any asset that must preserve sharp graphic edges.
- 2Convert phone photos from HEIC to JPG first if the portal is even slightly compatibility-sensitive.
- 3Use lighter delivery formats only after you confirm the portal accepts them and the listing still looks trustworthy.
- 4Save the successful route as the default prep workflow for the next batch of listings.
Common mistakes to avoid
These are the shortcuts that usually create a second cleanup pass later.
- •Do not assume marketplace forms will handle HEIC just because the phone can preview it.
- •Do not over-compress product images until they look cheap or noisy.
- •Do not use JPG for assets that must keep transparency around the product.
- •Do not let every seller or operator invent a different export process.
