Official-source seller guidance

Marketplace product photo requirements.

The practical difference between a platform rule, a recommendation, and a useful preparation default. Choose a marketplace to check real photos locally in your browser.

Core marketplace guides checked 14 July 2026; new workflow sources checked 27 August 2026. Marketplace policies can change.

Official sourcesEvery material rule links to the marketplace that published it.
Required vs recommendedHard limits are kept separate from quality and workflow advice.
No compliance promiseAutomated checks help triage a batch; sellers still review content and category rules.

Four guides. Four different rule sets.

Each guide includes a five-photo browser check and clearly labels what Seller Photo Prep Studio can prepare automatically.

The 500 px minimum, 1600 px recommendation, 12 MB limit, and prohibited overlays.

Open Shopify guide
Catalogue workflow

Product photo file naming & SKU workflow

Build predictable per-product filenames, preview marketplace-aware slots, and keep the export tied to the right catalogue record.

Open naming guide

Practical catalogue workflows

Four jobs between camera roll and upload.

Each workflow adds a distinct local decision tool, then routes the actual photos through the free checker before the App Store.

Background & framing

White background and subject fill

Estimate frame fill and separate Amazon main-image rules from general marketplace advice.

 Catalogue cleanup

Exact and near-duplicate review

Separate repeated files from useful product angles without deleting source evidence.

 Format workflow

HEIC, WebP, JPEG and PNG output

Choose a target format, preserve transparency deliberately, and keep originals untouched.

 Product identity

File naming and SKU workflow

Preview predictable per-product filenames and marketplace-aware image order.

How to use the guidance

Start with the source. Finish with the actual output.

  1. 01
    Identify hard limits

    Check minimum dimensions, maximum bytes, and restricted main-image content.

  2. 02
    Choose a preparation default

    Resize and convert without presenting a useful workflow choice as a marketplace mandate.

  3. 03
    Review generated pixels

    Inspect crop, detail, background, text, props, and category-specific requirements before upload.

Prepare full folders locally

Turn the guidance into one checked upload pack.
