Playable Ad Size Limits by Network (Google, Meta, Unity, TikTok)

All ad networks support up to 5 MB per HTML file. Smaller files load faster. Here’s a quick reference and how to keep your creatives optimized.

Size Limits by Network

All ad networks support a 5 MB cap per HTML file. Google, Meta, TikTok, Unity Ads, IronSource, Mintegral, AppLovin, Liftoff, Moloco, and others all expect a single HTML file with assets embedded.

All ad networks support up to 5 MB per file. Smaller files generally load faster and can perform better. Use compression and lean assets when you want the quickest load times.

Quick Reference Table

All networks support up to 5 MB. When exporting, use a tool that lets you select the network and apply compression for faster loading if needed.

How to Stay Under Playable Ad Size Limits

• Use a playable end card maker with built-in compression.
• Compress images before adding; use WebP or optimized JPG/PNG.
• Prefer simple animations; avoid large video or many high-res images.
• Export per network so the tool can target that network’s limit.

Why Size Limits Exist

Ad networks support up to 5 MB so creatives can load without draining data or battery. Slow-loading ads hurt user experience, so smaller files often perform better. Use compression and lean assets for the best delivery and performance.

All ad networks support a 5 MB cap. Smaller files load faster on typical mobile networks. If you want faster load times, reduce image count or resolution, or use a tool that applies compression at export time.

Building a Size-Conscious Workflow

From the start, design with size in mind. Use as few images as necessary and compress them before uploading to your playable ad maker. Prefer solid backgrounds or simple gradients over large photos when possible. If you use a no-code tool, enable the compress-assets or network-specific export option so the final HTML is optimized. Check the estimated size in the export modal before downloading; if it is over the target, reduce assets and export again.
