How it works

The Image Border Adder places a solid-color frame around any image directly in your browser. Set the border width in pixels and choose a color using the color picker, then see an instant preview. Download the result as PNG when it looks right.

Borders serve both practical and aesthetic purposes: adding whitespace creates a clean presentation effect similar to a photo mat, while a colored border can reinforce brand identity or make an image stand out on a web page or in a document. The border is added outside the original image dimensions, so the image content itself is not affected.

This tool is useful for preparing social media images that need a consistent frame, adding a visible edge to screenshots so they stand out against white backgrounds, and creating a polished look for product photos in e-commerce listings.

Worked example

Add a white mat border to a photo for a presentation

Upload the photo.
Set border width to 40 pixels.
Select white (#FFFFFF) in the color picker.
Confirm the preview shows a clean white frame.
Click Download to save the framed PNG.

A photo with a 40-pixel white border on all sides, giving it a gallery-mat appearance.

Common mistakes to avoid

Setting a very large border width and then being surprised the overall image dimensions have grown significantly.
Choosing a border color that blends into the background where the image will be placed, making the border invisible.
Not accounting for the added border pixels when the image needs to fit a specific size constraint.

Key terms

Border: A frame of uniform color added around the outer edge of an image, increasing its overall dimensions.
Mat: In photography, a flat border placed around a print when framing, typically white or off-white, to create visual separation between the image and the frame.
Canvas expansion: Adding pixels around an image's original boundaries, increasing total width and height without scaling the original content.
