Creative specifications

Upload creatives on the campaign page. Each creative is reviewed separately and serves only once approved; pending and rejected creatives are never shown. Approved creatives are locked; to change one, upload a new creative.

Formats

Format	Creative type	Where it appears
Banner	Image	A strip inside the app’s UI, refreshed every 30 s or more
Interstitial	Image or video	Full screen at a natural break; the user can close it
Rewarded	Video	Full screen, opted in by the user in exchange for an in-app reward

Images

File types	PNG, JPEG, WebP, GIF
Maximum size	1 MB
Maximum dimension	4096 px
Banner sizes	Exactly one of 320x50, 320x100, 300x250, 468x60, 728x90
Interstitial size	Short side at least 320 px and long side at least 480 px. Use 1080x1920 (portrait) or 1920x1080 (landscape); the ad server prefers creatives matching the device orientation

Supply several banner sizes in one campaign: the ad server picks a size that fits the device’s screen width.

Video

Container / codec	MP4, H.264
Maximum size	30 MB
Duration	5 to 60 seconds
Recommended	720x1280 or 1080x1920 portrait, AAC audio, 15 to 30 s, faststart

Videos are downloaded completely before they are shown, so a smaller file loads on more devices in time. Rewarded videos must be watched to the end to grant the reward.

Destination URL

Every creative needs a landing page URL starting with https://. It opens in the user’s browser when they tap the ad. Make sure it works on mobile.

Review guidelines

Qartvelo Ads reviews every creative and its landing page before it can serve. If a creative is rejected, the reason is shown on it; fix the issue and upload a corrected creative. Pending or rejected creatives can still have their destination URL edited.

Formats targeted by the campaign

If a campaign targets specific formats, you can only upload creatives of those formats. A campaign serves a format only when it has at least one approved creative of that format.
