About the startup

PostDecks shows exactly how a post will look on Facebook, Instagram, X, LinkedIn, Stories and Carousels, with each platform's real cropping and caption limits. Then get it signed off: send clients a link to approve or comment on, with no login or dashboard for them, or export a PDF proof sheet and PNGs. The previewer runs in your browser, so your images stay private. Pro adds the approval links, email alerts when a client responds, branded exports, and unlimited saved clients.
