+Creation support
+----------------
+
+Starting with GDAL 3.10, the HEIF driver supports creating new HEIF file through the CreateCopy()
+interface.
+
+The available creation options are:
+
+-  .. co:: CODEC
+      :choices: HEVC, JPEG, JPEG2000, AV1, UNCOMPRESSED
+      :default: HEVC
+
+      The encoding used for the image file format.
+
+-  .. co:: QUALITY
+      :choices: 0...100
+      :default: 50
+
+      To set the quality factor. This is codec dependent. Higher number correspond to better
+      visual quality and typically larger files. It is ignored for UNCOMPRESSED.
