Turn a generated image into a banner
Any image in your media library, including one your assistant generated, can become an exact-size banner ready to submit, with a warning when the crop cuts something off.
October 12, 2026. Image models make large square or wide pictures. Display ads need exact sizes, such as 300x250 or 728x90, at 220 KB or less. Adprime Zero now bridges the two.
- Make a banner from any image in your media library. Pick the size. The product crops the image (or fits all of it, if you ask), compresses it under the size limit, and saves the banner next to the original. Making a banner is free and never submits anything.
- Read the warnings. A wide 728x90 or 320x50 crop keeps only a thin band of a square picture. The result says how much was kept and what was cut, so you or your assistant can regenerate the image at the banner's shape or fit the whole picture instead.
- Submit by media id. Pre-check and submit take the banner's media id, so the image never has to pass through the chat.
- Look before you submit. Each banner comes with a private preview link, valid for 72 hours, that opens in a browser tab.
Where: the connector tools upload_media, list_media_library, get_media_item, and derive_banner_from_image, plus account_media_id on pre_check_creative and submit_creative; the REST route POST /media-library/:id/derive-banner; and Variant Studio in the dashboard, which now builds banners from the source image you attach.
PNG and JPEG images work. Convert WebP or GIF images first.
