Get to Know Auto-Sizes by Celtra

Let's talk about the most time-consuming and daunting creative task: versioning.

Imagine launching a campaign that involves hundreds of messages personalised for different consumer groups across the purchase journey. Now imagine manually producing creatives on that scale for hundreds of sizes.

Are you suffering from these challenges in creative production?

  • Manual resizing thousands of creative assets for every marketing campaign
  • Delays in campaign launches
  • Poor campaign performance because of the lack of creative testing
Technology to generate advertising images and videos in minutes
