- Selective Page Application: Apply color changes to the entire document or only to specific pages.

Tips & Best Practices
Note on Color Replacement
True color replacement in PDFs is complex. Our tool simulates the effect by overlaying a tinted layer. This works well for simple color changes but may not be perfect for documents with many gradients or images.
Check Invert on Photos
Inverting colors will turn photos into negatives. If your document has important color photos, you may want to apply the effect only to text-heavy pages.
