Create Viral TikTok Ads
TikTok Ads

TikTok in-feed ads require 9:16 vertical video at 1080 x 1920 pixels. Recommended duration is 9-15 seconds for best performance, though up to 60 seconds is supported. Max file size is 500 MB with H.264 encoding. AdCreate exports TikTok-ready files that meet all these requirements.

AdCreate generates the video creative you need for Spark Ads. The workflow is: create your vertical video in AdCreate, post it organically to your TikTok account, then authorize it as a Spark Ad in TikTok Ads Manager using the post's authorization code.

TikTok recommends 21-34 seconds for auction ads, but 9-15 seconds often performs best for conversion campaigns. For awareness goals, 15-30 seconds works well. The key metric is completion rate — shorter videos that get watched fully outperform longer ones that get skipped.

The top-performing TikTok ads mimic organic content: use a direct-to-camera creator, quick cuts, trending text animations, and casual audio. Avoid polished brand aesthetics. AdCreate's avatar and UGC templates are designed specifically for this native style.

Yes — TikTok reports that 80% of their users watch with sound on, but adding text overlays and captions still increases engagement by 55.7%. Captions ensure your message lands in sound-off environments (shared links, quiet browsing) and improve accessibility. AdCreate auto-generates burned-in captions for every video.
