What adding a border to an image does
A border is a band of solid color around the outside of a picture. It works like the mat around a framed print: it separates the picture from whatever sits next to it and gives the image a finished edge.
This tool makes the canvas larger rather than painting over your photo. It fills a new, bigger rectangle with your chosen color and then places the original image in the middle at full size. That means no part of the picture is covered or cut off. The final width and height are your original dimensions plus twice the border thickness, because the band is added on all four sides.
Why people add borders
A white border is a classic look for photos shared online, and it stops light images from blending into a white web page. A dark border can make a screenshot stand out in a document or slide. Matching a border to a brand color is a quick way to make a set of images feel consistent.
Borders also help with screenshots of interfaces whose edges are hard to see against a page background, and with product photos that need a clean margin before being placed in a layout. Because the added band is part of the image, it travels with the file wherever it is posted.
How to add a border with this tool
- Drop an image onto the upload area, or click to choose one.
- Set Thickness with the slider. It runs from 2 to 100 pixels and starts at 24.
- Click the Color swatch to pick any color. The default is white (#FFFFFF).
- Click Apply border. The preview updates to show the framed result.
- Click Download to save it, or Start over to load a different image.
The saved file is a PNG named after your original with -bordered added, so beach.jpg becomes beach-bordered.png. Your original file is never changed, and the work is done in your browser without uploading anything.
Practical notes and limits
Thickness is measured in pixels of the original image, not in percentages. A 24 pixel border looks substantial on a small 300 pixel icon and barely noticeable on a 6000 pixel photo, so scale the slider to your image. For example, a 1200 by 800 image with the default 24 pixel border becomes 1248 by 848.
If you change the color or thickness after applying, click Apply border again to refresh the preview and download. The tool draws one uniform, square-cornered border only. It does not offer different widths per side, gradients, shadows, or rounded frames. For softened corners, run the result through the Round Corners Tool. If the finished picture is bigger than a site allows, the Image Resizer can bring it down to exact dimensions.
Because the output is always PNG, a photo converted this way can be larger on disk than the original JPG.
