Property Value

Type: String

The conversion mode of the thumbnail.

Default value is "*.*=SourceFile".


This property specifies a format string for a desired conversion mode. It consists of masks=mode pairs separated by semicolon. Each pair includes a set of file masks separated by comma and a corresponding mode. In general, this string has the following syntax:


When HTML5/Flash Uploader prepares the upload request, it parses the conversion mode format string from the beginning to the end and extracts such pairs. For each file selected for upload HTML5/Flash Uploader gives the first pair. If it finds a file mask in this pair which matches the file extension, it applies a corresponding mode. If no appropriate file mask found, HTML5/Flash Uploader checks the next pairs in the same way.


If there is no file mask corresponding to the original file extension or appropriate mode HTML5/Flash Uploader does not send this converted file.

This is a list of supported conversion modes:

  • SourceFile means that the selected file will be uploaded from a user's computer without any changes.
  • Thumbnail works as follows. If the selected file is image, it will be resized using the parameters listed below and uploaded as JPEG file. Otherwise, a converted file will not be sent.
  • Icon means that a system icon associated with the selected file will be uploaded.
  • Zip means that a ZIP archive of the selected file will be uploaded. Not supported in HTML5 Uploader.
