How to make a 9 photo collage for Instagram

FAQ about 9 photo collages
How do I make a 9 photo grid for Instagram?
Open this page — the “9 photos · Instagram” template is already selected. Drag nine pictures into the upload area, set the aspect ratio to 1:1, and click Download PNG. The 3×3 grid lands in Instagram with no cropping.
What is the resolution of the 3×3 collage?
Convertilo exports the collage in high resolution — up to 2160 px on the long edge. Each cell is around 700 px, which is plenty for crisp Instagram publishing even on large screens.
What is a photo dump and does 3×3 fit?
A photo dump is a “dump” of snapshots from a trip or event published as a single collage. The 3×3 grid is the most popular photo-dump format — nine moments in one picture, easy to scan in the Instagram feed.
Can I rearrange photos in a 3×3 grid?
Yes. Click any cell and pick another picture — the current one is replaced. You can also clear a cell (the photo returns to the gallery at the bottom) and re-drag the right shot.
