How to add a black border or black bars to a photo

Create a clean black frame without cropping the image or reducing its original resolution.

Quick answer: choose your photo in Simple Border, select an aspect ratio, and pick black. Increase the frame size for a border, or set it to 0 for black bars.

A black border can create a gallery-style frame, separate a light photo from the background, or make a landscape or portrait image fit a social-media format with black bars instead of cropping.

Add a black border with Simple Border

Open a photo. Start Simple Border and choose the photo or video you want to frame.
Choose an aspect ratio. Use Original for a frame around every side, or select square, 4:5, or 9:16 when the photo needs to fit a specific format.
Select black. Open the color picker and choose black for the solid border.
Set the frame size. Increase it for a black border on every side. Set it to 0 when you only want black bars in the unused space created by the selected aspect ratio.
Export. Save the finished image or share it directly. The app adds the border as pixels instead of cutting into the original photo.

Black border vs. black bars

Black border or frame

Add space around all four sides when you want a consistent, print-like frame. Choose the Original ratio and increase the border width.

Black bars

Add space mainly above and below or at the sides when the original photo does not match the chosen output ratio. Set the frame size to 0 so only the unused space becomes black bars. The full photo stays visible.

Choose the right format

Original: adds a uniform black frame without changing the photo's shape.
Square (1:1): useful for square social posts and consistent carousel dimensions.
Portrait (4:5): fills more vertical space in the Instagram feed.
Vertical (9:16): prepares landscape or square media for Stories, Reels, and other full-screen placements.

For black bars, choose the target ratio and set the frame size to 0. Simple Border fills the unused canvas with black instead of zooming into the image, so important details stay in the frame.

Suggested colors and blurred borders

Black is not the only option. The color picker can suggest colors that already appear in your photo, which helps the border feel connected to the image. You can also switch from a solid color to a soft blurred border when you want the empty space to feel like an extension of the photo.

For a consistent gallery or portfolio, use the same solid black border across a set. For Stories or videos, blur can feel more immersive while still avoiding a crop.
