About Image Border Adder

The Image Border Adder is a browser-based utility that lets you quickly frame photos and screenshots with a customizable border. All processing uses the Canvas API inside your browser, so images are never uploaded to any server — your privacy is fully protected.

Border width ranges from a fine 1px line to a bold 100px frame, adjustable via a slider. The color is freely selectable with a color picker, and you can choose between solid (straight edge) and rounded (corner radius) styles to match different design needs.

Perfect for presentation slides that need consistent framing, social media photos that need to stand out, decorative borders for banners and thumbnails, or screenshots in blog posts that need visual separation. PNG, JPEG, and WebP images retain their original format, while other formats are automatically converted to PNG for reliable output.

How to use Image Border Adder

Drag and drop an image file or click to browse and load it.
Adjust the border width with the slider, pick a color, and select a style (solid or rounded).
Check the preview, then click the download button to save the bordered image.
