![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Configure the com.glide.attachment.max_size property to control the maximum size (in megabytes) permitted for an uploaded attachment.
The com.glide.attachment.max_size system property controls the maximum size of uploaded attachment in megabytes. If the value of property com.glide.attachment.max_size is 1024 then the max
allowed attachment size is 1Gb.  
Note:  
A real attachment size is calculated through multiplication 1024 \* value of the com.glide.attachment.max_size property.

Ensure that the property com.glide.attachment.max_size is set to <kbd class="ph userinput">1024</kbd> or less.
