How to add a border around a photo on iPhone

To add a border around a photo on iPhone, fit the photo inside a larger fixed-ratio canvas and use the visible canvas as the surrounding matte. Choose a solid colour, gradient, or texture, adjust the spacing on each side, and export the result as a PNG.

ScreenEdit also lets you add a thin border directly around the edge of the photo. The outer matte and the per-image border are separate treatments, and you can use either one or combine them.

Outer matte or per-image border?

People often use “border” to describe two different effects:

• An outer canvas or matte is the larger area around the photo. Its width comes from the space between the photo and the edge of the final image.
• A per-image border is a line that follows the photo’s own edge. It stays attached to the photo when you change its size or position.

Use an outer matte when you want a generous white border, a coloured frame, or more breathing room around the complete image. Use a per-image border when the photo only needs a thin edge to separate it from a similar background.

For a broader look at ratios, backgrounds, and multi-image layouts, read the guide to framing photos for social media on iPhone.

Add space without automatically cropping the photo

ScreenEdit’s default fit behavior keeps the whole photo visible inside the frame. That makes it possible to add space around an image even when the photo and outer canvas have different proportions.

This is a no-crop starting point, not a restriction. You can still crop the photo deliberately when a tighter composition is what you want. If preserving the original edges matters, check that all four remain visible before exporting.

Choose a shape for the finished image

The border sits inside one of ScreenEdit’s fixed output ratios:

• 1:1 for a square frame
• 4:3 for a balanced shape with more height
• 5:3 for a moderately wide frame
• 16:9 for the widest composition

The ratio controls the outside edge of the exported image. The photo can keep its own proportions inside that shape, with the matte filling the remaining space.

These ratios are design options, not promises about how X or Threads will render every preview. Pick the one that suits the image, then inspect the attached PNG before publishing.

How to create the border in ScreenEdit

1. Import the photo into ScreenEdit on iPhone.
2. Choose a 16:9, 5:3, 4:3, or 1:1 frame.
3. Keep the photo fitted inside the canvas if you want every edge to remain visible.
4. Scale and position the photo to set the matte width.
5. Choose a solid colour, gradient, or texture for the outer canvas.
6. Add a per-image border if the photo needs a more defined edge.
7. Adjust rounded corners or a subtle shadow if they improve the separation.
8. Export the finished composition as a PNG.

After ScreenEdit renders the PNG, it opens the native iOS share sheet so you can save or share the finished image.

Keep the border visually balanced

Even spacing is a useful default, especially for a simple white or neutral matte. It gives the photo a stable, print-like frame.

The spacing does not have to be mathematically equal to look balanced. A subject near one edge may need more room on that side, and a short label may justify extra space above or below the photo. Judge the complete image rather than treating the border as a fixed measurement.

Use contrast when the photo and matte are too similar. A dark photo can sit clearly on a light canvas, while a light photo may need a darker matte or a thin per-image border. Keep shadows and textures restrained so the photo remains the focus.

The finished file should contain the composition you intend to share: the complete photo when you choose fit, the surrounding matte, and any thin border or finishing effect you added. The social platform may present its preview differently, but opening the image will show the exported PNG itself.
