How to blur part of an image with Canva | Image processing that naturally hides faces and backgrounds

Blurring part of an image in Canva is useful when you want to make a face less noticeable, a room in the background, or a person in the photo naturally hidden. The key is to think about blurring by dividing it into ``expression to hide'' and ``processing to make information unreadable.''

Steps to blur only part of a photo with Canva

1. Add a photo to your design and select a photo.

2. Open blur-related editing items from Edit image.

3. If you can specify a range, set the brush size to be slightly wider than the target.

4. Trace the face, background, signboard, etc. multiple times making sure there are no thin areas left at the edges.

5. Check not only the original size, but also the size close to the smartphone display and the enlarged view.

6. Reopen the exported image and check that the editing has been reflected.

Tips for naturally blurring your face

If you trace only the outline of the face, it may be easier to identify the person. It will look natural if you include a little hairline and outline, and blur it wide enough that the border with the background is not suddenly cut off. In photos of multiple people, people other than the main character, faces reflected in mirrors, and people on posters can easily be overlooked.

There is a difference between blurring the background and hiding personal information.

Blurring is used to soften the life-like feel of the background and improve the impression of the photo. On the other hand, documents, addresses, smartphone screens, car license plates, name tags, etc. may be readable if the blurring is weak. It is safer to cover this information with a shape or crop the original image.
