I just launched a free tool to help marketers, designers, and content creators quickly find up-to-date image and video specs for all major social platforms (Facebook, Instagram, YouTube, Twitter, LinkedIn, etc.).

Key features:

Searchable and filterable by platform and formats

Copy direct links to individual specs (great for sharing with teams/clients)

Downloadable templates with safe zones (image sizes, ad dimensions)

Lightweight, fast UI – no login or signup required

It was built to eliminate the need to constantly Google or guess spec sizes. Would love feedback or suggestions for platforms/types to add!
