Add Border to Image

1. 1Add a JPG, PNG, WebP, GIF or BMP picture.
2. 2Set the border width and choose a colour, or tick transparent padding.
3. 3Round the picture's corners, the outer corners, or both.
4. 4Choose PNG or JPG and download.

The border width is a percentage of the picture's shorter side and is the same on all four edges, so a 5% border on a 4,000 × 3,000 photo adds 150 pixels on each side, making it 4,300 × 3,300. The picture itself is drawn at its original size and is not resampled.

Rounded corners are a radius in percent of the shorter side; 50% on a square picture makes a circle. Rounding the picture leaves the border colour showing in the corners, while rounding the outer edge cuts the whole result, leaving transparent corners.

JPG has no transparency, so whenever the result has transparent areas — transparent padding or rounded outer corners — it is saved as PNG automatically. Otherwise you can choose JPG for a smaller file.

Images are decoded by the browser, redrawn on a canvas and re-encoded on your own machine. Nothing is uploaded, so there is no waiting on a queue and no copy of your photos anywhere else.

A 4,000 × 3,000 photo with a 5% white border

1. Border = 5% of 3,000 = 150 px
2. Width = 4,000 + 2 × 150 = 4,300 px
3. Height = 3,000 + 2 × 150 = 3,300 px

Result: A 4,300 × 3,300 picture with an even 150-pixel white border.

• Use a border colour taken from the photo, or plain white or black, for a clean look.
• Thin borders (2–4%) suit web pages; thicker ones (8–15%) look like a printed mount.
• Choose PNG when the picture will sit on a coloured background and has rounded corners.
• Keep your original; the border cannot be removed later without cropping.
