About the Add Border Tool
This puts a solid-colour border or frame around an image. A border helps a photo stand out against a busy page, gives product shots a clean consistent look, adds breathing room for a print or collage, or rounds off the corners for a softer, modern feel. Choose the thickness, colour and corner radius, and download the framed image.
Want text overlaid instead of a solid frame — a caption, credit or logo? Try Add Watermark.
How it works
The tool draws a new canvas larger than your image by the border width on all sides, fills it with your chosen colour, and places the image in the centre. If you set a corner radius, it rounds both the outer frame and the image inside it — clipping the image to the rounded shape, so the corners become transparent in the exported PNG. The border width, colour and radius all update the preview live.
Assumptions and behaviour
- The border is added outside the image, so the final dimensions grow by twice the border width.
- Corner radius rounds both the frame and the image, clipping the photo to match.
- With rounded corners, the exported PNG has transparent corners (since a rounded shape can't fill a square).
- The border is a single solid colour.
Limitations
- Solid colour only — it doesn't do gradient, patterned, textured or multi-layer (double) borders, or a photo-style drop shadow.
- Rounded corners produce transparency, so if you place the result on a coloured background it will show through the corners; keep square corners for a fully opaque image.
- It adds a uniform border on all four sides; you can't set different widths per side. Need to trim the image first? Use Crop Image before adding a border.
- Output is PNG; convert or compress afterwards if you need a smaller file.

Privacy
Adding the border runs entirely in your browser with the Canvas API. Your image is never uploaded or stored.
