Percentage or pixel width
Percentages keep the border proportional across images of different sizes; pixels give exact, repeatable results.
Any colour
White for a print look, black for a gallery style, or a brand colour from the colour picker.
Gallery mat bottom
A deeper bottom edge, a classic framing convention that makes pictures look visually centred.
Inner keyline
A thin line between photo and border, like the bevel of a picture mount.
Batch framing
Frame a whole series consistently, ideal for portfolios and feeds.

Image Border Generator FAQ
Does adding a border change my photo?
No. The border is added around the outside, so the picture itself is untouched. The image becomes larger by the border width on each side.
Should I use pixels or percentages?
Use a percentage when framing images of different sizes so the borders look the same relative to each picture. Use pixels when you need an exact measurement, for example to meet a template or a print requirement.
Why make the bottom border deeper?
Picture framers often cut the bottom of a mat slightly wider. Our eyes perceive the optical centre of a rectangle as a little above the true centre, so a deeper bottom makes the picture look correctly placed rather than sinking.
How do I make a square image with a border for Instagram?
Add the border here first, then use the Image Resizer or Instagram Post Resizer to fit the framed image to 1080 × 1080 or 1080 × 1350.
Can the border be transparent?
This tool adds solid colour borders. For transparent rounded edges, use Image Rounded Corners, and for decorative frames such as Polaroid or film styles, try the Photo Border Maker.
Borders, mats and visual breathing room
A border does for a picture what margins do for a page of text: it separates the content from its surroundings and gives the eye a resting space. On a busy web page or social feed, a white border makes a photo look like a printed object rather than a fragment of the screen, which is why bordered feeds have remained popular since the early days of Instagram.
Framers use several conventions that translate well to digital images. A mat, the card surround inside a frame, is usually at least as wide as the frame moulding and often several inches wide on a small print. Weighting the bottom slightly more, sometimes called bottom-weighting, counteracts an optical illusion that makes centred objects look low. A thin bevel or keyline where the mat meets the picture draws the eye inward.
Choosing the colour is mostly about contrast. White borders make colours look darker and richer; black borders make them look brighter and more saturated. Neutral greys are the least distracting. A brand colour can tie a series of images together, but use it sparingly so it does not compete with the pictures themselves.
Measuring borders as a percentage keeps a series consistent even when the images differ in size, which is common with photos from different cameras or crops. For professional printing, convert the desired border width in millimetres to pixels at the print resolution; 300 pixels per inch is about 11.8 pixels per millimetre.
