Hide and finish

Blur what nobody else should see, then give the picture a finishing touch: a frame around it, or a colour behind a see-through picture.

For anyone sharing a photo with a face, a name, an address or a number plate in it, and for anyone who wants a photo to look finished.

The pictures show a phone. On a computer the tools sit down the left side with their names, and the rest works the same way.

Blur private details

  1. Tap Redact.
  2. Drag a box over what should not be seen. It turns into a blur straight away.
  3. Drag the box to move it, or a corner to make it bigger or smaller.
  4. Add as many boxes as you need. Duplicate copies the selected box, Remove deletes it.

What to look for before you share

Things people often forget to hide:

  • Faces of people who did not agree to be shared, especially children.
  • Number plates, house numbers and street signs near your home.
  • Names, addresses, phone numbers and codes on letters, parcels, tickets and screens.
  • Anything reflected in a window, a mirror or sunglasses.

Add a frame

  1. Tap Frame.
  2. Tap a frame under the picture. None takes it off again.
  3. Change the frame with the settings above the frames. Every frame has a Color; most also have a Size, and some let you set how far in the frame sits (Offset) or how round its corners are (Radius).

Write on a Polaroid

Polaroid gives the picture a white border with room underneath, like an instant photo. Then tap Annotate, pick Text and write a date or a few words on the white strip.

A colour behind a see-through picture

Some pictures have see-through parts: logos, cut-outs, stickers and round pictures saved as PNG. Whatever is behind them shows through, so they can look different in every app.

  1. Tap Fill.
  2. Tap a colour. It shows everywhere the picture is see-through.
  3. The chequered square keeps those parts see-through.

On a video

The video and GIF editor has no Redact, Frame or Fill. To hide something in a video's thumbnail, open it with Edit this frame: Redact is there. Choose the thumbnail shows how.

Ideas

Share a screenshot safely

Blur names, phone numbers and profile pictures with Redact before you post a screenshot of a chat.

A logo that works everywhere

Give a see-through logo a white background with Fill, so it never disappears on a dark screen.
