This tool runs entirely in your browser using WebAssembly. Nothing is uploaded, nothing is stored, and you can even turn off your internet connection before you start.

How it works

  1. Drop the images you want to frame.
  2. Set the border width in pixels. For a phone photo 40 to 100 px is a visible but slim frame.
  3. Choose white, black, grey or a transparent border.
  4. Press Add border and download the results.

Frequently asked questions

How wide should the border be?
It depends on the image size: 40 px is slim on a 4000 px photo and wide on a 600 px screenshot. Roughly 2 to 3 percent of the longer side reads as a neat frame.
Does the image get smaller?
No. The border is added outside the picture, so the canvas grows by twice the width in each direction and the photo keeps every pixel.
Why does a transparent border come out white?
JPG cannot store transparency. Choose PNG or WebP as the output format to keep the border transparent.
Are my images uploaded?
No. The border is added in your browser. The free plan handles 3 images per run, 20 MB each and 10 runs per day.
