Add Border to Image Online – Frame Photos with Custom Margins

The Add Border tool allows photographers, social media managers, and graphic creators to frame images with clean, uniform borders and decorative outer margins. Supporting PNG, JPG, WEBP, and GIF source files, the tool mathematically expands the outer bounding box of your image canvas by your specified margin thickness while preserving your exact original aspect ratio and pixel resolution. This is particularly valuable when preparing product photos for e-commerce stores requiring uniform white borders, formatting portrait shots for Instagram square feeds without awkward cropping, or adding contrast frames around light screenshots on white website backgrounds. Output files can be exported as high-resolution PNG or compressed JPEG. Limitations to keep in mind include the fact that adding outer borders naturally increases the overall pixel width and height of the exported file by twice your chosen border thickness value.
