Blur Image Edges

Drop your photos into the form and pick what happens at the edges. The middle of the frame stays sharp, and the effect builds gradually toward the edges.

Four modes

• Blur softens the edges, like a lens with shallow depth of field.
• Fade into a background dissolves the edges smoothly into white, black, your own color, or transparency. With transparent edges the file is saved as PNG, so the photo sits on a card or collage without a frame.
• Darken creates a vignette: the edges darken and pull the eye toward the center of the frame.
• Photo on a blurred copy places the whole shot in a square, a 4:5 post, a 9:16 story, or a 16:9 cover, and the empty margins are filled with its own blurred copy. That way the photo is not cropped when published on social media.

Settings

"Sharp center size" sets how much of the frame stays untouched, and "transition softness" sets how gradually the effect builds toward the edges. The center can be an oval or a rectangle matching the proportions of the photo.
