+## Docker load
+
+`docker load` restores a Docker image from a tar archive.
+
+It is mostly used in conjunction with `docker save` command to transfer a Docker image without using Docker Hub or another registry.
+
+To load an image from a file named `nginx-backup.tar`, the following command can be run:
+
+```
+docker load -i nginx-backup.tar
+```
+
+This command also recognizes gzip, bzip2 and xz compression, and decompresses the file automatically. Therefore, it can be used even without decompressing manually:
+
+```
+docker load -i nginx-backup.tar.gz
+```
