One of the big trends on Instagram is merging two or more photos into an Instagram collage, so you can show multiple scenes in one photo.

While Instagram now allows you to post up to 10 individual photos in one post, a collage is still a fun way to show off multiple photos together.

Instagram doesn't currently have a feature that lets you create collages directly within the app, but there are plenty of third-party photo editing apps you can use (plus one of Instagram's own, which you'll explore below). Most of them let you easily share your collage photo directly to Instagram.

Here are seven great apps that make it easy to create photo collages to share on Instagram.
