How to Add a Border to an Image
A border is a small touch that makes an image look finished. It frames a photo like a print, separates a white-edged screenshot from a white page so it doesn't disappear, and gives a set of images a consistent, deliberate look.
This guide covers the practical reasons to add a border, how to choose a colour and width that suit the job, and one neat trick: using an even border to fit a non-square photo into a square feed without cropping anything out.
Add Border
Add a solid colour frame around your image in any width.
Why add a border at all
Borders solve real problems as well as looking nice. A white or light image on a white web page blends into the background; a thin grey or black border gives it a clean edge. A coloured frame can tie a photo to a brand palette. And a generous white border creates the classic matted, gallery-print look that makes a single photo feel considered.
Nothing gets cropped
A common worry is that adding a border will eat into the picture. A good border tool does the opposite: it grows the canvas outward to make room for the frame, so your entire original image stays visible inside it. The border sits around the outside, adding to the overall dimensions rather than covering any content.
Choosing colour and width
There's no single right answer — it depends on the effect:
- A few pixels of grey or black: a subtle outline that just defines the edge.
- A thick white border: a polaroid or gallery-mat look that feels premium.
- A brand colour: ties social posts together into a recognisable set.
- A bold contrasting colour: makes a thumbnail pop in a busy feed.
The square-feed trick, and doing it privately
Feeds like Instagram often prefer square images, and cropping a rectangular photo to fit means losing part of it. Adding an even border around the photo squares up the outer dimensions instead, so the whole image survives inside a neat frame. PixelResize adds the border entirely in your browser — pick any colour, drag the width slider with a live preview, and download. Nothing is uploaded, and PNG images keep their transparency. Combine it with the Resize tool if you need an exact final size.
Key takeaways
- A border frames a photo, separates it from a white page, and adds a finished look.
- The canvas grows outward, so no part of the original image is cropped.
- Match colour and width to the goal — subtle outline, gallery mat, or bold thumbnail.
- An even border can square up a rectangular photo for square feeds without cropping.
- Adding a border in the browser keeps your photo on your device.
