Celtra: Your trusted ads design tool

Designing ads from scratch is one of the most time-consuming and risk-prone parts of marketing. Every creative needs to earn attention, stay on brand, meet channel specs, and perform across increasingly complex media environments. When teams rely on static files and copy-paste production, timelines slip, errors increase, and brand consistency starts to fade.

The right ad design tool solves that by helping teams build once and produce variations fast, while maintaining governance and performance alignment. Celtra is built for enterprise brands and global teams that need a reliable way to produce on-brand, activation-ready creative that drives results at scale. If your biggest pain is constant resizing, localization, or creative that cannot keep up with media optimization, Celtra gives you a system that makes those changes predictable instead of painful.

What is an ads design tool and why marketers need one

An ads design tool is a platform that enables marketers and designers to create, manage, and adapt ad creatives across channels and formats from one place. It provides the structure needed to scale creative production without sacrificing quality, compliance, or performance. Instead of (re)building every version manually, teams use modular designs and templates to generate the formats and variations each campaign needs.

Celtra goes beyond basic design tools by unifying the whole advertising creative workflow so teams can move from approved design to performance-ready, activation-aligned ad creatives, without endless back and forth. It supports scalable production, AI-powered personalization, and guardrails that keep every output brand-safe and optimized for media execution.

With Celtra, teams can:

• Build modular templates once and reuse them across campaigns with creative structures designed for performance and testing
• Scale variations across formats, markets, and languages using AI-powered automation that keeps quality and relevance high
• Apply governance and approvals that protect the brand while giving local and media teams room to move
• Use AI-driven insights and predictive scoring to prioritize concepts and launch creative that is proven to perform
• Update once at the template level so the creative can adapt as fast as media optimization cycles

How ad design tools work 

Creating ads is rarely just a design problem. The longest delays usually happen during adaptation, approvals, localization, and last-minute changes. This is also where performance suffers, because creative cannot evolve at the same speed as media optimization.

Ads design tools separate creative structure from creative content. Designers build flexible templates with rules and guardrails, marketers then update copy, images, offers, or language, and the system applies those updates across linked versions automatically.

For enterprise companies, this matters because the workload is constant:

• Multiple markets and languages
• Many formats per channel and placement
• Frequent promotional updates and refresh cycles
• Strict brand and legal requirements

Celtra helps marketing teams deliver consistent performance-informed creative at volume by eliminating repetitive work, applying AI-driven insights and predictive scoring, and keeping outputs aligned to the approved system and media needs.

Designing ads for every channel without losing control

Each channel has different placements, specs, and creative behaviors. They also require different storytelling approaches and testing volumes to perform well. Without a shared system, teams end up duplicating work, introducing errors, and chasing approvals across multiple files.

Celtra makes cross-channel production manageable: templates are built to adapt to requirements, media structures, and optimization cycles, and teams can preview, edit, and approve placement-ready assets in one platform. When something changes, you update once, and the right versions update everywhere, supporting faster testing, iteration, and creative refreshes mid-flight.

This is not just a theoretical benefit. Teams using Celtra see measurable gains once cross-channel production runs through shared templates instead of duplicated workflows. Siemens reduced average ad creation time to just 2 minutes and increased creative productivity by 8.2x across global B2B campaigns. Wolt, operating across 30+ countries, used the same template-driven approach to achieve over 20x higher productivity while producing more than 300,000 creatives with a small central team.

Who is Celtra for

If your team is constantly juggling formats, languages, approvals, and last-minute updates, an enterprise ads design tool can remove bottlenecks and protect quality.
