Can the file type of ‘save as’ and’ download as’ in the PPT be kept only in JPG and PNG， Block other file type ？
Hello @xuxiaofei
If I understand correctly, you’d like to keep only mentioned options for Save as and Download as menus of the File tab, is that correct? If it is correct indeed, I’m afraid there is no way to limit options of these menus.
Possible workaround here is to implement a separate button in your app that will call forcesave by the request to the document command service and then sending a request to Conversion API with the link returned to the callback handler of your app to convert the file. After that you can develop an interface that will return the converted file back to the user and provide a possibility to download it. In the meantime, in the editor you can simply disable downloading options with permissions.download parameter: Permissions | ONLYOFFICE
