This feature is only included in SoftMaker Office Professional and NX Universal.
In the Android/iOS version, the command is locked. (To unlock the command, see Welcome.)
You can use the command Compress pictures 
to reduce the memory size of images in Presentations. In this way, you reduce the file size of the document and save capacity on your device or when sharing the document.
You can use the command effectively if your document contains pictures that were embedded in the document when you inserted them using the option Save within document (see Inserting pictures).
Note: Pictures that were instead saved in the document as a reference to an external picture file are not affected by compression. However, when executing the command, you have the option of subsequently embedding these pictures in the document and compressing them here at the same time.
Proceed as follows:
| 1. | In your document, select one or more pictures that you want to compress. An additional ribbon tab Picture appears at the top right of the ribbon. |
Tip: If you want to compress all pictures of the document, just choose the ribbon command File | group File management | Compress all pictures and continue with step 2.a.
| 2. | Choose the ribbon command Picture | group Adjust | Compress pictures . |
| 2.a | If your selection contains only pictures that have been saved in the document, the dialog box "Compress pictures" opens immediately. |
| 2.b | If your selection contains pictures that have not been saved in the document, a message appears before the dialog box opens, asking whether you want to embed these pictures now (see description below). |
| 3. | In the Resolution section of the dialog box, choose between the predefined qualities or enter a custom resolution. |
| In the Options section, you will find two more settings (see description below). |
After saving the document, you will notice a change in the file size.
Other options
▪Delete cropped areas of the pictures
| If you have cropped an image in your document using the command Pictures | Cropping and you do not need the truncated remainder, enable this option. Once you press OK, the cropped image area will be deleted and only the crop will be retained. |
▪Embed and compress external pictures
| This option allows you to embed and compress pictures in the document that you did not insert using the option Save in document, but which are only saved in the document as a reference to the original external file. |
| To explain this option, the following cases may occur: |
| a. You have selected only pictures that were not saved in the document. After choosing the command Compress pictures, a message appears asking if you want to subsequently embed the pictures. If you click on Yes, this option is already preselected in the following dialog box. |
| b. If pictures are selected that have already been saved in the document, this message also appears. If you click on Yes (or also No), this option is freely selectable in the following dialog box. |
| c. If you have selected only pictures that have already been saved in the document, this message does not appear. This option is not selectable in the dialog box. |
