Check ad copy and images against platform limits

Liveby Superpowers ad specs checker

Checks ad copy and images against Google, Meta, LinkedIn and TikTok limits before you upload them.

Counts characters the way each platform does (Google and TikTok count Chinese, Japanese and Korean characters as 2), checks how many headlines and descriptions each format needs, flags editorial problems such as all caps or repeated punctuation, and reads each image's format, file size, dimensions and aspect ratio to say which placements it fits. Specs come from each platform's help pages, listed with the date they were checked.
