Build multi-frame image carousels sized for Instagram, LinkedIn, and other social platforms. Choose between square (1080×1080), portrait (1080×1350), landscape (1080×608), or custom dimensions. Add text to each frame, upload individual background images or span a single image across multiple frames for a seamless swipe effect. Customize colors, fonts, and font weights per frame or globally. Preview your carousel with gap indicators, reorder frames with drag controls, then download all frames as a ZIP of PNG images ready to post.
