Add a border to an image

Three quite different borders

Solid adds an even frame of one colour around the photo. White is the classic gallery look; black suits dark images; a colour ties a set of images together.

Square pad puts the photo on a square canvas with the border colour filling the rest. This is the fix for feeds that crop to a square — instead of losing the sides of a wide photo, the whole picture fits with colour around it.

Blurred does the same fit-to-square, but fills the surround with an enlarged, blurred copy of the photo itself. It is the look messaging and social apps use, and it reads far better than a flat colour because the frame shares the image's palette.

Thickness is proportional

Set as a percentage of the shorter side, so the same setting looks right on a phone photo and a camera file. Five percent is a noticeable frame; one or two percent is a fine line; fifteen percent is the wide-margin gallery print look.

Why square padding matters

Feeds crop aggressively. A 16:9 landscape photo posted to a square feed loses about 44% of its width — often including whoever was standing at the edge. Padding to a square means the whole photograph survives, and the frame becomes a deliberate part of the composition rather than a loss.

Batches

Up to twenty images with the same border, returned as a zip. Consistent framing across a set is most of what makes a feed look coherent.
