What you can do
Detect common sensitive information on your device and hide names, phone numbers or faces before sharing. Use the text eraser to remove text on solid or nearly solid backgrounds.
How to use it
- Open Image editor in FileBox and switch to redaction, or choose Image redaction from the Photos share sheet.
- Choose detection categories, or tap words, draw boxes or brush manually to cover addresses and other details.
- Choose rainbow bars, rainbow grids, pixelation, blur, noise blocks or color bars. Adjust the coverage and check for missed details.
- To remove text on a solid background, select the eraser and tap a detected text block. Tap its original position again to restore it, or use undo and redo. Switching tools preserves detection and selections.
- Check each edit, then overwrite or save a copy; the Photos extension saves a new image.
Before you start
The text eraser fills from surrounding backgrounds and works best on solid or nearly solid screenshots. Complex textures may leave visible traces. Dotted outlines are editing aids and are not exported; the tool does not recover obscured text. Detection runs on-device and may miss sensitive content. Export removes original image metadata; Live Photos become still images. The Photos extension accepts inputs up to 80 MB and 25 megapixels.
