How to hide text and names in images with Canva | How to black out addresses and QR codes

If you want to hide text in an image in Canva, the basic method is to cover it with an opaque shape rather than blurring it. Target information includes address, name, phone number, email address, order number, QR code, and login screen ID. Unlike blurring to maintain the atmosphere of an image, text information needs to be made not only "unreadable" but also "unguessable."

Steps to black out letters and names with Canva

1. Add the image to Canva and zoom in to see the text you want to hide.

2. Add a rectangle from Material or Element.

3. Choose a color for the shape and set the opacity to 100%.

4. Place the shape from one end of the string to the other, leaving a little space on the top, bottom, left and right.

5. If multiple strings are close, cover a larger range without dividing them into smaller pieces.

6. Duplicate and export the image to share only the edited version while keeping the original design.

Do not hide only “part” of the QR code/barcode

QR codes and barcodes may remain unreadable if some parts remain. It is safe to cover the entire cord and surrounding margins, rather than just blurring the center of the pattern. If you have taken an image of the slip, please also check the name, postal code, tracking number, and store name.

Why a dark colored cover is easier to understand than a white one

If you place a white square on an image with a white background, it will be difficult to see where you have hidden it, and you may miss any leaks before saving. Even if white is required for the design to be published, it is safe to hide it with a dark color when editing, check, and then adjust the colors at the end.
