Optimize Slack images while preserving metadata
For image work where metadata matters, keep that requirement in the instruction that starts the optimization.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Preserve Image Metadata
Tool to preserve exif and other metadata during kraken.io image optimization. use when you need to maintain metadata while compressing images.
Why this helps
A generic compression step may not fit workflows that rely on EXIF or other image metadata.
- Keep the metadata requirement explicit in the workflow.
- Reduce repeated manual handling of images requiring metadata preservation.
- Start the asset task from Slack context.
Setup
Build it in a few focused steps.
- 1Connect Slack and Kraken.io to Notis once through the portal.
- 2Create an automation in the portal or ask Notis conversationally.
- 3Write one instruction to optimize public image URLs shared in the relevant channel while preserving image metadata.
- 4Choose the Slack channel message trigger and a channel for run reports.
- 5Test with a suitable public image URL and confirm the returned result.
