Latest Release
2025.1 — June 2, 2025
Black Highlighter 25.1 includes a bunch of new enhancements for Shortcuts.
Unified Action
All redaction actions have been combined into a single unified action, making it easier to find the action you need. The single “Redact Image” action includes the ability to redact specific words, detect personal information, or just redact everything.
Auto-Hidden List Actions
Three actions support the ability to manage your auto-hidden words list inside Shortcuts. Get the list, add, or remove words from it, all in Shortcuts.
Output Formats
The unified redact action has an option to specify what file format to use when redacting: match the input, or export as either PNG, JPEG, or HEIC.
Bug Fix
When deleting a word from the auto-hidden words list, other words maintain their active state instead of being reset to active.
