Add a Solid or Gradient Border Around an Image
Frame a picture with an even border of any thickness, in a colour you pick or a ready-made gradient.
About the Image Border Generator
The thickness slider covers 1 to 120 pixels, starting at 20, and the border is drawn evenly on all four sides. Two styles are available. Solid uses a colour picker, so the frame can be matched to a page background or a brand palette. The gradient option lays a diagonal blend across the frame instead, which suits a header image that needs to look finished without any colour decisions being made.
It is worth being precise about what happens to the file. The border is added outside the picture rather than painted over it, so the exported image is larger than the one you started with by twice the thickness in each direction — a 20 pixel border on an 800 by 600 photograph produces an 840 by 640 result, with none of the original content covered. Output defaults to PNG, several images can be framed in one run under the same settings, and the framing is carried out by your own browser.
Key Features
- Thickness from 1 to 120 px: One slider covers everything from a hairline keyline to a broad gallery-style mount.
- Pick the border colour: Solid mode opens a colour picker so the frame can match an exact brand or background shade.
- Ready-made gradient: The gradient style draws a diagonal blend across the frame for a finished look with no colour choices to make.
- Nothing is covered up: The frame is added around the outside, so no part of the original photograph is hidden beneath it.
- Consistent across a batch: Apply identical framing to a whole set so a gallery or a document looks uniform.
How to Use the Image Border Generator
- Add one or more images to frame.
- Set the thickness slider — thin values read as a keyline, larger ones as a mount.
- Choose solid and pick a colour, or switch to the gradient style.
- Check the preview and export.
How It Works
A new canvas is created at the source dimensions plus twice the border thickness on each axis. It is filled first — either with your chosen colour, or with a diagonal linear gradient running corner to corner — and the original image is then drawn inset by the border width. There is no library involved. Two constraints follow from that approach: the frame is uniform, so per-side thicknesses are not available, and the gradient style uses a fixed blue-to-purple pair rather than colours you choose. If you need a gradient in specific shades, generate it with the gradient background tool and composite it yourself.
When You Need It
A funeral director preparing an order of service places portraits across the pages, and the photographs come from relatives in every conceivable size and crop. A consistent border pulls them together so the printed booklet looks composed rather than assembled in a hurry. Those images are family photographs shared in confidence during a bereavement, which is not material anyone would want passing through an anonymous image site. Curators laying out an exhibition handout and volunteers producing a memorial display frame images for the same visual consistency.
