Everything renders locally — nothing is uploaded. Pick an option above to get your files.

Export notes

Carousel slides export at one identical size, named in swipe order.
Stories & Reels use 1080×1920; safe-zone guides are editor-only and never exported.
Video uses MP4 when your browser supports it, otherwise WebM or a still poster.
Direct posting needs a server, so carouselBuilder hands off to your share sheet or downloads.
