Add Border to Image — Solid Inner / Outer, Adjustable Width
Add a solid-color border to your images online: outer grows the canvas, inner keeps the size, with proportional width and custom color, live preview and a final-resolution readout. Works on desktop, tablet & mobile — batch, local, no upload.
Adding a border places a ring of solid color around an image — for card-style framing, a consistent album look, or padding for social posts. This tool offers two modes: outer adds the border outside the image so the canvas grows; inner draws the border just inside the original edges so the size stays the same. Border width is a percentage of the short edge (consistent across a batch), the color is white / black / gray or custom, and a live preview shows the final resolution. Processing runs entirely in your browser — no upload.

Border FAQ
Outer adds the border outside the image so the canvas grows (e.g. 1000×1000 with a 3% border becomes ~1060×1060); inner draws inside the original edges, keeping the size but covering a ring of edge content.
The page shows the final resolution live for the current preview image; for outer, final size = original + 2× border width, where the width is a percentage of the short edge.
