Product page headers introduce your app on its listing, while Search assets appear in discovery. Compare their sizes and prepare both in Shipper.
Header and Search reach people in different places
A product page header is a wide creative asset displayed on an app's product page. It can set the tone for the app or game once someone opens the listing. A search results asset appears in App Store search, where people are browsing and deciding what to explore.
That difference should guide your design. Give the Header room for a clear brand story. For Search, make the main idea legible at a glance, since the creative appears in a discovery context. As an example, a habit-tracking app might use a broader lifestyle message in its Header and a focused daily-routine idea for Search. This is a hypothetical example, not a tested result.
Both are optional creative assets, distinct from app screenshots and app previews. Screenshots show the app in use; Header and Search assets can communicate broader brand and marketing messages. Apple explains the distinction in its Asset Library documentation.
Choose the right image specs
Product page Header: 21:9, 3840 × 1646 px. Apple accepts JPEG or PNG images.
Search results: 3:2, from 1920 × 1280 px up to 3840 × 2560 px. Apple accepts JPEG or PNG images.
Neither image may contain an alpha channel or transparency. Apple also lists a 16:9, 5244 × 2950 px PNG option for both placements. A compatible universal creative asset can be reused in Header and Search Results, but it is a separate option from Shipper's dedicated specs. See Apple's creative assets specifications for the current rules.
Shipper currently provides dedicated Header (3840 × 1646 px) and Search (3840 × 2560 px) canvases. It does not currently provide the universal Header + Search spec as a combined export. Choose the dedicated destination you need rather than treating a screenshot size or a mockup crop as a Header or Search export.
Design and preview both placements with Shipper
Start with the same visual direction, but compose each asset for its own placement. For the Header, use the wider canvas to express the app's identity without crowding the edges. For Search, simplify the message and recheck the crop at smaller viewing sizes. Keep any product UI you show faithful to the real app.
In Shipper, create the Header and Search assets as editable designs using their dedicated sizes. Preview them in the Product Page and Search contexts to review hierarchy, readability, and how the assets sit beside other listing elements. That preview is a design check, not proof that an asset has been approved or made public.
You can design and export PNGs with Shipper Free, without a watermark. If you are also preparing ordinary screenshots, see our App Store screenshot guidelines for their separate requirements.
How Asset Library approval and publishing work
App Store Connect's Asset Library can store creative assets independently of a new app version. You can upload an asset, submit it for review, and reuse it after approval in an eligible placement. In App Store Connect, the Header and Search Results controls let you select compatible assets for each destination.
Apple also documents a useful option for apps already live: you can select an approved creative asset for the current version and publish that placement update without submitting a new app version. That is different from uploading an unapproved asset, and it does not mean every type of App Store content can be changed without review. Follow the exact steps in Apple's guide to managing creative assets.
With Shipper PRO, you can send supported Header and Search assets to App Store Connect from the same project as your screenshots and metadata. Review the Target App, locales, specs, and selected assets before shipping. The Shipper App Store Connect publishing workflow handles delivery of supported content, not Apple's asset review, placement approval, or public release.
Before considering the work finished, check the export dimensions and transparency, review the two placements in Preview, then confirm each asset's approval and placement in App Store Connect. Once the change is public, check the live listing rather than relying on a successful upload alone.
