The rise in popularity and use of HEIF/HEIC(High Efficency Image Format) means your project's image processing also needs to be able to handle this format. The current default version of imagemagick installed on heroku:20 dynos is a version 6.xx and does not support processing heic image files.

This Heroku buildpack vendors a version of ImageMagick with WEBP and HEIF support binaries into your project.

This one works was built for Heroku stack 20.

The tar file in the /build folder currently contains:

Version: ImageMagick 7.1.0-29

You will need to build a new binary if you want to use a newer or different version. To build a new binary see How to Build a New Binary

From your projects "Settings" tab add this buildpack to your app in the 1st position:

https://github.com/yespark/heroku-imagemagick-buildpack

NOTE: _To ensure the newer version of imagemagick is found in the $PATH and installed first make sure this buildpack is added to the top of the buildpack list or at "index 1".

Since the installation is cached you might want to clean it out due to config changes.

heroku plugins:install heroku-repo
heroku repo:purge_cache -app HEROKU_APP_NAME

The binary in this repo was built in a heroku:20 docker image running in a local dev environment. However, there is a script called build.sh made to build a tar file through docker easily, it will be copied to the build directory. Then you should commit this changes to your git, and adjust the buildpack url previously mentionned just above.
