Background filling and composition
This image background filler turns any photo into a complete cover layout. By using a scaled, blurred copy of your image as the canvas, it acts as a natural background filler that prevents harsh borders or empty space when adapting a photo to a new aspect ratio.
Instead of cropping your original image to fit a specific shape, the background fill process expands the canvas. The original image sits on top, ensuring nothing is cut off. You can adjust the padding to control how much of the blurred layer remains visible.
Aspect ratio control
Select standard aspect ratios like 1:1, 4:5, or 9:16 to fit specific platforms, or use the original ratio to simply add breathing room around the subject. When you fill png background or jpeg images, the tool automatically calculates the necessary canvas size to fill the background.
More padding shrinks the foreground image, revealing more of the background filler image. This is useful for creating no-crop layouts where the entire original photo must remain visible.
Blur strength and overlay tints
The background blur hides distracting details from the underlying layer, keeping focus on the foreground. To prevent sharp edges from repeating, the background scale control slightly zooms the base layer before blurring.
You can also apply an overlay color to tint the fill image background. Adjusting the overlay strength helps unify the tones, making the subject stand out against a darker or color-washed backdrop. The shadow controls separate the sharp foreground image from the soft background.
