Example
Example: a 40 px black border around an 800 × 600 picture
The picture: an 800 × 600 drawing of a red sailboat on blue water under a pale sky, saved as PNG. Settings: Border width 40, Border colour Black, Output format Keep original format.
- The border is added outside the picture, 40 px on every side: 800 + 2 × 40 = 880 wide and 600 + 2 × 40 = 680 high.
- Nothing is cropped or scaled: the boat sits in the middle at its own 800 × 600.
- The download stays a PNG and gets -border in its name: sailboat.png becomes sailboat-border.png.
| Image | Border | Result |
|---|---|---|
| 800 × 600 drawing | 40 px | 880 × 680 |
| 1280 × 720 screenshot | 20 px | 1320 × 760 |
| 1080 × 1080 post | 40 px | 1160 × 1160 |
| 4032 × 3024 phone photo | 40 px | 4112 × 3104 |
| 4032 × 3024 phone photo | 80 px | 4192 × 3184 |
An 880 × 680 PNG with an even black frame. On a 4032-pixel phone photo the same 40 px is only 1 % of the width, a thin line; 80 to 100 px reads as a frame there.
How it works
- Drop the images you want to frame.
- Set the border width in pixels. For a phone photo 40 to 100 px is a visible but slim frame.
- Choose white, black, grey or a transparent border.
- 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.
- How do I add a black border to a photo?
- Choose Black under Border colour, set the width — 40 px to start — and press Add border. White, black and grey are solid colours; Transparent adds empty space, which only PNG and WebP keep.
- Can I frame several images at once?
- Yes: drop several and each gets the same border width in pixels, so a small screenshot and a large photo get the same number of pixels, not the same share of their width.
- Are my images uploaded?
- No. The border is added in your browser. The free plan handles 3 images per run, 20 MB each and 5 runs per day.
