AJN PDF explains when work stays in your browser and when a selected file is uploaded temporarily to complete an advanced task.
Many everyday PDF and image actions work inside the active browser session. Supported files are validated automatically, with policy details available on the dedicated limits page.
Advanced conversion, and security actions may temporarily upload the selected file only for the requested task. Temporary request files are scheduled for cleanup after the result is returned or a handled error occurs.
For an on-device workflow, the browser Network panel can help confirm whether the selected document is transferred during that action.
Online requests use isolated temporary work areas and schedule cleanup after delivery or a handled error.
Advanced tools check availability first and show a clear unavailable state instead of pretending a task succeeded.
