How to black out something in a picture on iPhone
There are two good ways to black out part of a picture on iPhone: the Markup editor built into the Photos app, and a browser tool like Redacted that draws a solid box into the image itself. Markup is quickest for casual edits; the browser tool is safer for anything sensitive.
Option 1: the built-in Markup editor
- Open the photo in the Photos app and tap Edit.
- Tap the pen tip icon to open Markup.
- Tap + and choose the square shape, then set its fill to solid black.
- Drag and resize the shape until it covers the detail completely.
- Tap Done to save.
One caution: use the filled shape, not the pen or highlighter. Markup’s drawing tools are not always fully opaque, and a single pass over text can often be made readable again just by turning up brightness and contrast. That is one of the classic ways redacted images get unredacted. If you do use the pen, pick black at full opacity and go over the area several times.
Option 2: Redacted in Safari (nothing to install)
- Open Redacted on your iPhone.
- Tap to choose a photo, or paste an image if it is on your clipboard.
- Place a selection over the area you want to hide.
- Choose the black box mask (or pixelate or blur).
- Download the edited image.
The box is rendered into the pixels of a new file, the export strips metadata such as GPS location, and the photo never leaves your phone. You also get pixelate, blur, and emoji masks, plus automatic face detection.
What to black out before sharing
- Faces, names, and profile photos
- Addresses, phone numbers, and emails
- License plates, house numbers, and location clues
- Receipts, tickets, documents, and IDs
Blur, pixelate, or black box?
Black box is the strongest choice for sensitive text. Blur can look cleaner for casual sharing, while pixelation is useful for faces or details where you want a less severe look.
FAQ
Does this work in Safari?
Yes. Redacted works in modern mobile browsers, including Safari.
Is the iPhone Markup pen safe for hiding text?
Not always. Pen and highlighter strokes can be semi-transparent, and text under a thin layer can be recovered by adjusting brightness. Use a solid filled shape in Markup, or a dedicated redaction tool.
Does blacking out a photo remove its location data?
Not by itself. When sharing from Photos you can disable location in the share options. Redacted strips metadata, including location, from every export automatically.
Do I need to upload the photo?
No. The edit happens in your browser.
Can I save the result back to Photos?
Download the edited image, then save it from your browser downloads.
