Collage is a fun way to share photos with your friends while adding a caption. From birthdays, to celebrations, to family vacations, collages are a great way to put together fun memories so you can enjoy them forever. This article will teach you how to instantly create collages on your phone and then share them on Instagram for all your friends to see.
Steps

Step 1. Download Instagram, if you haven't already
Instagram is a free online photo sharing app, which allows you to edit and share photos with your friends, from your mobile device, with just the push of a button. To download it, go to the app store on your phone or other device and type “Instagram” into the search bar.

Step 2. Download a photo editing application that will allow you to create collages
You cannot make collage directly on Instagram, so you will need to use another photo editor app to make the collage, save it to your phone, and then upload it to Instagram. Before downloading the app, make sure that it gives you the option to create collages, because not all photo editing apps offer this option. Try Instapic Frames, Pic Collage, Collage Shaper, Photo Shaper, or Collage Maker.
- Instapic Frames is a free app that allows users to choose a frame for their photos, from different existing frames, edit photos individually, and upload the final collage directly to Instagram. This app is recommended for Instagram users because it uses the same format as Instagram.
- Pic Collage is a free app that lets you create collages in 15 different types of frames with up to 9 photos at a time.
- Collage Shaper is another free application which allows you to create collages of different shapes namely hearts, stars, peace signs, butterflies or palm trees.

Step 3. Make your collage
Select the photos you want to use and upload them to your chosen photo editing app. You will also need to choose a frame and depending on the application you are using, also choose a template and adjust the width of the borders.

Step 4. Save the collage to your photo gallery
Some apps, like Instapic Frames, allow you to upload the collage directly to Instagram. If so, then you won't need to save it to your phone first.

Step 5. Upload the collage to Instagram
To upload an image from your device to Instagram, click the camera button at the bottom of your screen, then select the button with the image of a polaroid, which appears right next to the image.

Step 6. Edit and share your collage
Pick any filter you want, for the collage (or do it without a filter) and share your artwork when you're done.
