How to Create High-Performance HTML5 Ads (No Code Needed)

HTML5 ads are one of the most powerful formats in digital advertising today. They're interactive, lightweight, and supported across nearly every ad network -  from Google Display to Facebook and programmatic platforms. But for many marketing teams, building them feels like a job for a developer.Good news: it doesn’t have to be.

How to Create High-Performance HTML5 Ads (No Code Needed)
In this post, we’ll show you how to create engaging, high-performing HTML5 ads without coding — and how the right tools can save your team hours of production time.

What Are HTML5 Ads, and Why Use Them?

HTML5 ads are banner ads built with HTML, CSS, and JavaScript - allowing for animation, interactivity, and responsiveness. They replace the outdated Flash format and are now standard across the Google Display Network, programmatic DSPs, and social platforms.

Here are a few reasons why HTML5 ads are worth your attention:
  1. Faster load times than static image ads
  2. Responsive across all devices and screen sizes
  3. Support for dynamic content like product feeds
  4. Interactive experiences that improve engagement
  5. Better tracking and performance reporting

Traditional Ad Creation vs. Visual HTML5 Builders

Traditionally, ad production involved designers exporting static banners, followed by developers coding animations manually. This process is time-consuming and difficult to scale - especially for performance-focused campaigns that require frequent updates.With Campaign Builder, that process is dramatically faster. You can:
  1. Build HTML5 ads visually with no code
  2. Use animation presets and timeline editing
  3. Create multiple ad sizes at once
  4. Export to any major ad network in a few clicks

Step-by-Step: How to Create HTML5 Ads in Campaign Builder

  1. Start a New Project
    ‍    Create a new campaign inside Campaign Builder. You can select from pre-made templates or start from scratch depending on your needs.
  2. Choose Your Ad Sizes
    ‍    Select from all standard IAB sizes such as 300x250, 728x90, and 160x600, or define your own custom dimensions to match your media plan.
  3. Add Your Creative Assets
    ‍    Upload logos, product images, call-to-action buttons, and background visuals. You can also connect to product feeds via CSV, XML, or Shopify to automate asset generation for catalog ads.
  4. Animate with the Timeline Editor
    ‍    Use the drag-and-drop animation editor to control how each element enters, exits, or reacts to user interaction. You can fine-tune timing and transitions without writing any code.
  5. Add InteractivityWant your ad to expand on hover or display more info on click? Campaign Builder allows you to add interactivity visually - no JavaScript required.
  6. Preview Across DevicesUse the preview mode to test how your ad looks across mobile, tablet, and desktop screens before publishing.
  7. Export to Any Format
    Once you're ready, export your ads to the formats you need:
    • HTML5 zip files
    • Static images (JPG, PNG, WEBP)
    • MP4 video files
    All files are compatible with over 20 ad networks including Google Ads, Meta, Adform, DV360, StackAdapt, and more.

Best Practices for High-Performing HTML5 Ads

  1. Keep file sizes under 150KB for optimal performance
  2. Use a clear and actionable call to action (CTA)
  3. Avoid excessive animation - less is more
  4. Use web-safe fonts for consistency across browsers
  5. Create and test multiple variations to find top performers

Scale Further with Dynamic Catalog Ads

If you're managing campaigns with multiple products or categories, Campaign Builder supports scalable catalog ads. Simply upload a product feed or connect your Shopify store and generate dozens (or hundreds) of ad variations automatically - all fully animated and personalized.
