Carousel Maker

Each slide exports as its own file rather than one combined image, because that's how Instagram's carousel upload actually works — you attach a sequence of separate images, not a single collage. Numbering files in the ZIP by slide order (slide-1.png, slide-2.png, and so on) keeps them easy to upload in the right sequence instead of having to guess from thumbnails.

Only the first slide shows in someone's main feed before they swipe, so it carries the same weight a single post's whole image normally would — a weak opening slide means a carousel never gets swiped through regardless of how good the following slides are. Building all slides at the same 1080×1080 size keeps the transition between them visually seamless as someone swipes, rather than having the frame jump or shift size partway through.
