Use Cases

Convert a document to grayscale to save on color ink when printing drafts or internal copies.

Tips & Best Practices
Subtle Changes are Best
Small adjustments to brightness and contrast are often more effective than extreme changes, which can wash out details or make dark areas lose texture.
Note on Simulated Adjustments
This tool simulates color adjustments by applying overlays. This is very effective for most documents but may not behave like a pixel-level photo editor for complex images.
