For agencies focused on display advertising, the need for a straightforward, time-efficient way to produce multi-size ad sets is a daily reality. While platforms like Celtra provide robust enterprise solutions spanning creative, analytics, and cross-channel activation, many agencies discover these broader systems can add unnecessary complexity to what is fundamentally a production workflow challenge. If your priority is to design once, generate every required ad size, and deliver consistent campaigns without weeks lost to manual resizing, it’s crucial to consider specialized alternatives.
What Makes a Celtra Alternative Right for Agencies?
Many agencies start their search for Celtra alternatives after encountering common roadblocks:
- Complexity and steep learning curves that slow down campaign launches.
- Enterprise pricing models misaligned with the scale or needs of smaller agency teams.
- Manual production steps for resizing and exporting standard ad formats.
- The challenge of maintaining brand consistency as creative is adapted for multiple platforms and dimensions.
For agencies, the main goals become clear: move quickly from an approved concept to a full ad set, keep brand elements accurate, and minimize repetitive work. This requires a platform that streamlines multi-size ad production, not an all-encompassing creative operations suite.
Definition: Automated Multi-Size Ad Production
Automated multi-size ad production refers to software workflows that allow designers to start from one approved master creative and rapidly generate all common ad sizes needed for display campaigns. Instead of building each format individually, the platform adapts layouts responsively, so logos, text, images, and calls-to-action remain visually optimized for every placement. This approach favors platforms built for speed and repeatability, such as SizeIM.

Agencies using SizeIM benefit from a clear, repeatable process tailored for efficiency and brand control. Here’s the core workflow:
- Choose a template: Start with a proven template or build from scratch for unique campaigns.

- Pick your sizes: Select every required dimension (for example, 300×250, 728×90, 160×600, 320×50, and more) in one step.
- Add your content: Insert headlines, offers, product images, and the primary call to action.
- Fine-tune layouts: Review and adjust element placement in each size to ensure legibility and brand impact.

How Much Time Does Automated Multi-Size Production Save?
Imagine a team creating one display ad concept for 12 network sizes. If traditional manual resizing, alignments, and QA take 12 minutes per format, that’s nearly 2.5 hours per ad set. Multiply this by 8 campaigns per month, and the agency loses nearly 20 hours to repeat tasks that could be spent on concepting, copywriting, or analytics. With responsive, automated workflows, most of these hours are saved, and consistency is dramatically increased.
