A busy background pulls the eye away from what you want people to notice: the dish, the outfit, the product or the room detail. Blurring everything outside a soft oval puts the focus back on the subject and leaves calmer space for a title. This tool does it without masking by hand: you drag the sharp area into place and the blur fades out around it.
You can crop to a 2:3 pin, a 9:16 long pin or a square while you work, or keep the original photo size. The photo is processed in your browser and never uploaded.
When a blurred background helps a pin
Background blur works best on photos with one clear subject: a plated recipe, a product on a table, a piece of jewelry, a plant or a person. It imitates the shallow depth of field of a fast lens, which makes phone photos look more considered and gives a title somewhere quiet to sit.
It is less useful on flat lays or room shots where the whole frame matters. For those, a text band works better: try the add text to image editor or the pin maker.
Tips for a natural result
Use a high feather value so the edge of the sharp area is not visible, and keep the blur moderate on photos where the subject has fine edges such as hair or leaves. Because the focus area is an oval, very irregular subjects may show a slightly soft edge. A small amount of background darkening adds contrast for white text.
Once the photo is ready, check it with the mobile preview to see how it reads at feed size.
