Using Chrome Alarms to Schedule Downloads in Bulk Image Downloader from URL List

Downloading images at the right time can be just as important as downloading the right images. The Bulk Image Downloader from URL List Chrome extension uses Chrome’s Alarms API to schedule download tasks with precision, even when you’re not actively monitoring the browser.

Why Chrome Alarms?

Chrome Alarms allow extensions to run scheduled actions in the background—even after some idle time. Bulk Image Downloader from URL List uses this system to trigger downloads exactly when you’ve scheduled them.

This means:

• You can prepare download tasks in advance.
• The extension will wake up and process them at the correct time.
• It checks every 30 seconds for any pending tasks.

How to Use Chrome Alarms in the Extension

1. Open the options page in Bulk Image Downloader from URL List.
2. Create a new task or edit an existing one.
3. Scroll to the Download Time section.
4. Use the date and time picker to set your preferred schedule.
5. Make sure Queued Downloads is disabled if using a scheduled task.
6. Save the task.

The task will be stored in Chrome’s local storage and the extension will wait for the scheduled time to initiate the download.

Notes on Behavior

• Tasks will only run if Chrome is open and active.
• You can set download times down to the minute.
• Once a task begins, it will proceed automatically, respecting all other task settings.

Tips for Using Chrome Alarms

• Use Chrome’s default behavior to keep it running in the background (enable background apps in Chrome settings).
• Combine alarms with ZIP packaging to schedule full archive creation.
• Double-check time zones—scheduled times are converted to your local time.

The alarm-based scheduling system in Bulk Image Downloader from URL List is ideal for automating large downloads at off-peak hours, overnight, or while you’re away from your desk.
