What is the resolution of each carousel slide?+
Every slide exports as a crisp 1080×1350 pixel PNG (Instagram 4:5 portrait ratio), maximizing feed screen space without unwanted compression.
How does the seamless panoramic spread work?+
When you choose a panorama layout, a wide image is divided precisely at the midpoint into two consecutive 1080×1350 slides with zero pixel overlap and zero white gap, creating an unbroken transition when swiped.
Can I mix portrait and landscape photos without awkward crops?+
Yes. Use the Single Fit layout to keep the full original photo with a clean background margin, or combine multiple photos into a 2-photo split or 4-photo grid slide.
How do I upload the slides to Instagram in the correct order?+
The exported ZIP contains numbered files: slide-01.png, slide-02.png, slide-03.png. In the Instagram app, tap create post (+), choose multiple photos, and tap the images in order starting from 01.
Is this carousel maker completely free and private?+
Yes. All slicing, layout composition, and ZIP packaging happen directly in your web browser. No photos are sent to a server, and no signup or watermark is required.
