This quick check reads dimensions, format, and filename only. It does not upload images, certify marketplace acceptance, or replace the Mac app's deeper subject, background, duplicate, and export checks.

Real local analysis
Included free. Inspect dimensions, sharpness signals, subject geometry, transparency, and background conditions locally.
Batch-safe output
Platform-sized batches. Mobile supports up to 50 photos with Pro; Mac supports larger packs up to 500. Originals remain unchanged.
Reports with every pack
Clear evidence. Free exports include a readable summary. Lifetime Pro adds complete CSV and JSON reports.
Duplicate control
Mac workflow. Surface exact and visually similar files before repeated angles or accidental copies reach the upload pack.
Product and SKU naming
Lifetime Pro. Group listing photos by product and produce predictable product and SKU filenames.
Current marketplace guidance

Straight answers
Before you put a real folder through it.
Need a fit check? Email support@vaultdevlabs.com.
Do my product photos leave my device?
No. Analysis and export happen locally on your iPhone, iPad, or Mac. The app does not need a marketplace login and does not upload your images to VaultDevLabs.
Which formats and batch sizes are supported?
Mobile supports free batches up to 20 photos and Pro batches up to 50. Mac supports larger packs up to 500. Supported formats vary by platform and selected source.
Will the app overwrite my originals?
No. Seller Photo Prep Studio creates a separate export pack. The source folder remains untouched.
Where can I install Seller Photo Prep?
The public App Store listing supplies the current compatible build for supported iPhone, iPad, and Mac devices.
Can I try it without paying?
Yes. The free tier imports up to 20 photos per batch and exports up to five prepared photos. Download it from the App Store before deciding on Pro.
What does “Lifetime Pro” mean?
Lifetime Pro is one non-consumable in-app purchase for the app, with no recurring subscription. The App Store supplies the current storefront price and handles purchase restoration.
Prefer the outcome, not the software?
We can prep the first 50 photos for you.
Send one folder and the target marketplace. We return a prepared ZIP and report from £29.
