How to Add a Border to an Image
2026-07-07
A border does more than decorate. It separates an image from the page behind it, which matters when a photo has white or very dark edges and would otherwise dissolve into the background. On a slide, a marketplace listing or a social post, that separation is the difference between a picture and a smudge.
Step by step
- Open the Add Border tool.
- Drop in one image or several.
- Set the width, colour and corner radius.
- Click Add border and download.
Choosing a width
Proportion matters more than any absolute number. Twenty to forty pixels reads well on a typical 1200 pixel photo; on a 4000 pixel image the same border is barely visible. A useful rule of thumb is roughly 2% of the shorter edge for a subtle frame, and 5% for a deliberate print-style mat.
Choosing a colour
- White — the classic photographic mat. Works on almost anything, and reads as intentional.
- A brand colour — ties a set of images together and is the quickest way to make mixed-source photos look like a series.
- Near-black — good for light, airy images on a light page.
Rounded corners
Rounding softens a screenshot and matches the interfaces most people now expect. Note that a rounded border requires transparency outside the curve, so rounded output is always saved as PNG — a square border keeps whatever format the source used.
Batching for consistency
Every image you add gets identical settings, which makes this a fast way to bring order to a batch: product photographs shot on different days, screenshots taken by different people, or a set of headshots that need to look like they belong together.
