Property Value

Type: Number

When you set the value that is more than 2 Gb, it is recommended to pass such value as a string.

Default value is 0.



Image Uploader Express restricts the maximum size of each user-selected file to 100 Mb. Image Uploader Professional and Print restrict the maximum size of each user-selected file to 2 Gb. See the Comparison of Image Uploader Editions topic for details.

This property limits only a single file. If you want to set limit for all selected files, use the maxTotalFileSize property.
