Screenshots and photos of documents often carry more than you meant to share: a phone number, an ID or card number, an address, a face, a QR code. Before posting or sending them, cover that information properly.
What to avoid
A semi-transparent highlighter or thin pen strokes can leave text readable once someone raises the contrast, and blur or mosaic on small text can sometimes be guessed. Use a solid, opaque box over anything private, and share a copy rather than the original.
Option 1: your phone's photo editor
Most gallery apps have a markup or drawing tool. If you use it, pick a solid shape or a fully opaque pen, cover each item completely, and zoom in to check the edges before you save.
Option 2: PhotoCleaner+
PhotoCleaner+ (our app) is made for this job. It suggests likely personal information, you review each box, and it exports a copy with solid masks — everything runs on your phone, nothing is uploaded.
- Open a photo, screenshot or PDF in PhotoCleaner+.
- Check the suggested boxes — phone numbers, emails, card numbers and similar text — and add your own by drawing.
- Move, resize or delete boxes until everything private is covered.
- Export the masked copy and share that. Your original is not changed, and saved copies carry no EXIF or GPS data.
