About image borders
A border (or frame) is a solid band of colour added around the edges of an image. A clean white border gives the classic polaroid or gallery look, a black border adds drama, and a coloured border can tie an image to a brand or theme. Borders are also handy for separating an image from a white page background.
This tool adds an even border on all four sides at the thickness and colour you choose, growing the canvas rather than cropping the photo. It all runs in your browser, so nothing is uploaded.
Border thickness is relative, not absolute. Forty pixels reads as a bold frame on an 800-pixel-wide photo but almost disappears on a 4000-pixel one straight off a camera. As a starting point, try around 2 to 3 percent of the image's shorter side for a subtle frame and 8 to 10 percent for a chunky polaroid feel, then adjust by eye in the preview.
Do your other edits first and add the border last. Cropping afterwards slices the frame off some sides, and resizing changes how thick it looks. The order matters most when a platform re-crops images to its own aspect ratio: a frame that fits the final shape survives, one added before cropping ends up uneven. Finish the composition, size the image for its destination, then frame it.
Frequently asked questions
How do I add a border to an image?
Upload your image, choose the border thickness and colour, and the framed result previews live. Download when it looks right.
What colours can I use?
Any colour — pick it from the colour swatch. White and black borders are the most common, but you can match a brand or theme colour exactly.
Does the border change the image size?
Yes. The output grows by the border thickness on each side, so a 40px border adds 80px to the width and height. The photo itself is unchanged.
Is my image uploaded?
No. The border is drawn entirely in your browser, so your photo never leaves your device.
Can a border fix a photo cropped too tightly?
Often, yes. A border acts as visual padding: a band in a colour close to the photo's edges gives the subject breathing room without touching the pixels themselves. It also helps when a platform's display shape would otherwise trim the edges of your image — the border gets sacrificed instead of the content. It cannot restore anything outside the original frame, though.
