If the selected format is PDF, you can register information such as the title, creator, etc. The information registered here can be confirmed in the properties window of a PDF viewer such as Adobe Acrobat Reader DC. In addition, the **Layout** item allows you to change the way the PDF is displayed when it is opened with a PDF viewer.

#### About the source metadata
101
+
102
+
We have seen cases where metadata (document properties) such as title, author, etc., set in the original printed file is unintentionally leaked when the converted PDF file is published. Due to the facts, CubePDF has a policy of automatically erasing such information.

If the selected format is PDF, you can set a password to protect the created PDF file. To set a password, first enable the **Encrypt the PDF with password** option, then enter the same password twice in the **Password** and **Confirm** fields.

However, if you share both passwords, the restrictions on printing, copying, etc. may not work properly depending on the PDF viewer. This is probably because the PDF viewer recognizes that the PDF file was opened with the owner password. For this reason, CubePDF is designed not to accept permission settings when it is shared with the owner password.

#### Attention about reconversion for the purpose of setting/removing passwords
129
+
130
+
In some cases, CubePDF is used to reconvert PDF files in order to set a password for the PDF file (e.g., by displaying the PDF file in Microsoft Edge or Adobe Acrobat Reader DC and then printing it). If you use this operation, the appearance of the PDF may differ from the original PDF due to the fact that the printing process is performed once. If your goal is to set a password for a PDF file, please consider using [CubePDF Utility](https://www.cube-soft.jp/en/cubepdfutility/) or [CubePDF Page](https://www.cube-soft.jp/en/cubepdfpage/).
131
+
132
+
Conversely, we have seen cases where PDF files are reconverted to remove passwords and other security settings set in the PDF file. However, some applications propagate various security settings when printing, in which case CubePDF will fail to convert. This operation is completely unsupported. And please note that no modifications will be made to change this behavior.

ただし、**管理用パスワードと閲覧用パスワードを共有した場合、PDF 閲覧ソフトによっては、印刷やコピー操作等の制限が正常に機能しない事があります**。これは、PDF 閲覧ソフトが管理用パスワードで PDF ファイルを開いたと認識するためと予想されます。そのため、CubePDF では、管理用パスワードと共用した場合、その他の操作に関する許可設定を受け付けないように設計しています。

また、管理用パスワードで PDF ファイルを開いたと認識された場合、閲覧用パスワードの除去も含めた全ての PDF 編集が可能になります。閲覧用パスワードを管理用パスワードと共用する場合、これらの動作を十分に理解した上でご利用下さい。

#### パスワードの設定・解除を目的とした再変換に関する注意
130
+
131
+
PDF ファイルに対してパスワードを設定する目的で、CubePDF を用いて PDF ファイルを再変換する事例が見られます(Microsoft Edge や Adobe Acrobat Reader DC 等で PDF ファイルを表示して印刷を実行)。この方法を用いた場合、いったん印刷処理が実行される都合上、元々の PDF と見た目が異なる可能性もあるのでご注意下さい。PDF ファイルに対するパスワード設定が目的の場合、[CubePDF Utility](https://www.cube-soft.jp/cubepdfutility/) や [CubePDF Page](https://www.cube-soft.jp/cubepdfpage/) の利用もご検討下さい。
132
+
133
+
また、これとは反対に PDF ファイルに設定されているパスワードや各種セキュリティ設定を除去する目的で PDF ファイルを再変換する事例も見られます。しかし、印刷を実行するアプリケーションによっては印刷時に各種セキュリティ設定を伝搬する事も多く、この場合 CubePDF は変換に失敗します。この操作に関しては、完全にサポート対象外となります。この挙動の変更を目的とした修正が行われる事もありませんので、ご了承下さい。
