InstAssist — Free Instagram Carousel Tools
InstAssist is a free, privacy-friendly set of browser-based tools for creating Instagram carousels. No sign-up required, no uploads to any server — your photos never leave your device.
Photo Splitter
Upload a landscape or panoramic photo and split it into perfectly sized square segments for an Instagram carousel post. Choose between 2 and 10 slides, drag to adjust the vertical crop, and download all segments as a ZIP file. Works with any aspect ratio — the tool automatically calculates the optimal number of slides.
How the Splitter works
- Upload a landscape or panoramic photo (JPG, PNG, or WebP)
- Choose how many carousel slides you want (2-10)
- Drag to adjust the vertical crop position
- Download all segments as a ZIP file
Peek Carousel Maker
Create a seamless swipe experience for your Instagram carousel. Upload multiple separate images and InstAssist composites each one with a small preview strip of the next image on the right side. When followers swipe through your carousel, the transition feels smooth and connected — encouraging them to keep swiping.
How the Peek Carousel works
- Upload multiple images for your carousel
- Reorder them by dragging or using the arrow buttons
- Adjust the peek offset (5-30%) to control how much of the next image is visible
- Optionally blur the peek strip for a teaser effect
- Download each image individually or all at once as a ZIP
