When working with attachments in offline mode, keep these general guidelines in mind for usability and a good user experience.
Note:  
Many of the issues discussed can be resolved using system properties. For more information, see [System properties in offline mode](https://servicenow-prod.fluidtopics.net/Jdej0yXGzimN1fO4RCnttw "Use the table to view system properties related to offline mode.").

Controlling offline attachment file types
:   Define which file types can be downloaded offline using the `glide.sg.offline.attachment.allowed_content_types` system property, for example, `image/png` or `image/jpg`. This
    property prevents irrelevant or unsafe files from being downloaded, keeping offline storage lean.

Limiting attachment file size for offline use
:   Use the `glide.sg.offline.attachment.max_size` system property to set the maximum size in bytes for a single attachment downloaded offline. Files exceeding this limit aren't downloaded and display as a
    placeholder, preventing large attachments, such as long videos, from causing performance issues or filling device storage.

Total attachment storage limit
:   Use the `glide.sg.offline.attachment.max_total_bytes` system property to cap the total storage space allocated for offline attachments. The default is 50 MB with a maximum of 2 GB, ensuring attachments don't
    fill up a user's device storage.

Image attachment handling in offline mode
:   Image handling when taking pictures in the activity stream differs by platform:

    * Android: Images are automatically compressed to approximately 75% quality and converted to JPEG format, regardless of the original file type.
    * iOS: Images are uploaded as is, with no compression or format conversion applied.
