 PAPERLESS_OCR_MAX_IMAGE_PIXELS=<num>
-    Paperless will not OCR images that have more pixels than this limit.
-    This is intended to prevent decompression bombs from overloading paperless.
-    Increasing this limit is desired if you face a DecompressionBombError despite
-    the concerning file not being malicious; this could e.g. be caused by invalidly
-    recognized metadata.
-    If you have enough resources or if you are certain that your uploaded files
-    are not malicious you can increase this value to your needs.
-    The default value is 256000000, an image with more pixels than that would not be parsed.
+    Paperless will raise a warning when OCRing images which are over this limit and
+    will not OCR images which are more than twice this limit.  Note this does not
+    prevent the document from being consumed, but could result in missing text content.

+    If unset, will default to the value determined by

+        Increasing this limit could cause Paperless to consume additional resources
+        when consuming a file.  Be sure you have sufficient system resources.
+
+    .. caution::
+
+        The limit is intended to prevent malicious files from consuming system resources
+        and causing crashes and other errors.  Only increase this value if you are certain
+        your documents are not malicious and you need the text which was not OCRed
