While it is technically impossible to "unhide" text if the original pixels were completely overwritten by a solid, opaque digital marker
If it's a "Marker" tool, use AI Restoration (Hugging Face/CodeFormer).
This is a very powerful suite of AI editing tools that runs free in the browser. You can use its adjustments to change brightness, contrast, and saturation to make underlying text visible.
Before diving into solutions, understand this: When you "paint" over text in a screenshot (using a highlighter, brush, or shape tool), you are not deleting the underlying data. In most screenshot editors (like Snipping Tool, Snagit, or even basic phone markup), the paint is a over the original image.
Reduce to -100 to remove color interference from the marker (e.g., if it was blue or red).
| Paint Type | Success Rate | Reason | |------------|--------------|--------| | (yellow/pink) | 80-95% | AI sees through it | | Thin digital brush (low opacity) | 60-80% | Edge detection works | | Solid opaque brush (black/white) | <10% | No data left – impossible | | Hand-drawn scribble | 30-50% | Depends on gaps |
Open the file in an online vector editor. Click the painted area. If you can "grab" the paint and move it, you’ve hit the jackpot. The text remains untouched underneath. Important: A Note on Privacy and Ethics
