In HashiCorp Packer, post-processors are used to perform additional actions after the machine image has been created by the builder and provisioners. These actions can include compressing the image, uploading it to a cloud provider, or converting it to a different format. Here are some of the available post-processors in Packer:

1. Docker save post-processor
2. Amazon Import post-processor
3. Docker push post-processor
4. Google Compute Engine export post-processor
5. Vagrant post-processor
6. VirtualBox export post-processor
7. VMware export post-processor
8. VMware OVF post-processor
9. AWS AMI Cleanup post-processor
10. Shell-local post-processor
11. Atlas post-processor
12. Null post-processor

Each post-processor has its own set of configuration options and is responsible for performing a specific action on the machine image. These actions are performed after the machine image has been created and provisioned, making post-processors a powerful tool for automating the image creation and distribution process.
