PhotoGrid's AI Instagram collage maker takes your photos and builds a finished collage in the format you need. Pick 1:1, 4:5, 3:4, or 9:16 before AI starts, and the layout is composed around that choice from the beginning.
Describe the style you want
From a quick photo dump to a full profile grid, every Instagram post has a different shape. Pick the one that fits what you are making.
Use one strong portrait or group shot as the anchor, then add two or three supporting details around it — food, outfits, scenery, or close-ups. AI decides which photo needs more space and builds the rest around it.
1Add up to 10 photos from your phone or desktop. A mix of portrait shots, landscape photos, and close-ups gives AI more variety to work with and makes the final layout more interesting.
2Select 1:1, 4:5, 3:4, or 9:16 for the format you are posting to. AI builds the composition around that choice. Add a prompt to set the mood and aesthetic, or skip it and let AI decide on its own.
3The first version is ready in seconds. Swap the style, adjust the background tone, try a different layout, or download it as is. No watermark on the file.
PhotoGrid supports four Instagram formats: 1:1 for a square feed post, 4:5 and 3:4 for portrait feed posts, and 9:16 for Stories. Choose the format before AI generates and the composition is built around it from the start.
PhotoGrid creates one finished collage image per export. For posting multiple photos as separate swipeable slides, use Instagram's native carousel feature and upload your photos individually. This tool creates one finished collage image, not separate carousel files.
Yes. PhotoGrid generates an AI collage in the right proportions for a 9-grid layout, with a grid guide showing where to crop each section. Crop the sections in order and post them to Instagram — your profile builds into one seamless image.

No. Download your finished Instagram collage with no watermark on the file.
PhotoGrid supports up to 10 photos in one upload, enough for a mix of scene shots, portraits, and close-ups in one layout.
AI works to keep faces and key subjects in frame when composing the layout. It arranges the composition around your original photos and doesn't regenerate or alter the people in them.
Yes. PhotoGrid works in a mobile browser, so you can start an Instagram collage from your phone without installing an app.
A collage combines multiple photos into one single image: one post, one download. A carousel is multiple separate images in one swipeable Instagram post. This tool creates collages. For carousels, post your photos individually using Instagram's native carousel feature. The AI video generator is worth exploring if you want motion for Reels instead.
Photos from a trip, a weekend, or just a good day often end up sitting in a camera roll. A finished Instagram collage gives them somewhere to go. Make one for free and download it with no watermark.
