Borders that make photos look finished

A simple white border gives photos a gallery look, keeps edges from blending into a white web page and makes prints easier to frame. This tool adds a border sized as a percentage of your photo, so it looks balanced on any image.

Instagram and other apps crop tall and wide photos into their own shapes. Choose Square, 4:5 or 9:16 and the border extends to that shape, so your whole photo fits without anything cut off. Fill it with a colour, a gradient, or a blurred copy of the photo itself, and add rounded corners, an inner outline or a soft shadow.

How to add a border to a photo

    Choose, drag in or paste an image.

  3. 3

    Choose the canvas shape

    Keep the original shape or fit the picture into square, 4:5, 9:16 or 16:9.

  4. 4

    Style and download

    Add rounded corners, an outline or a shadow, then save at full resolution.

Frequently asked questions

How do I post a full photo on Instagram without cropping?

Choose Square or 4:5 as the canvas shape. The border fills the extra space so the entire photo fits.

Can I use a blurred background instead of a colour?

Yes. Choose Blurred photo and the border is filled with a softened, enlarged copy of your picture.

Will my photo be resized?

No. The photo stays at its original size; only the canvas around it grows.
