Resize Image

Resize Image changes an image’s dimensions. Provide either width, height, or both; when only one dimension is present, the original aspect ratio is preserved.

Inputs

Input	Type	Required	Description
Image	File	Yes	The image to resize.
Unit	`pixels` or `percentage`	Yes	How width and height are interpreted. Defaults to `pixels`.
Width	Positive number	No	Target width in pixels or as a percentage of original width.
Height	Positive number	No	Target height in pixels or as a percentage of original height.
Fit	Enum	Yes	How the source fits when both dimensions are supplied. Defaults to `cover`.
Position	Enum	Sometimes	Alignment for `cover` or `contain`. Defaults to `center`.
Background	String	For `contain`	Color used to fill empty space. Defaults to `#000000`.

Percentage dimensions are converted from the source metadata and rounded down to whole pixels. For example, width 50 means half of the original width.

Fit modes

Fit	Behavior
`cover`	Fills both target dimensions, cropping overflow as needed.
`contain`	Fits the whole image inside the target and fills remaining space with Background.
`fill`	Stretches the image to exactly the requested dimensions, even if the aspect ratio changes.
`inside`	Preserves aspect ratio and stays within both target dimensions.
`outside`	Preserves aspect ratio while meeting or exceeding both target dimensions.

Position offers top, bottom, left, right, corner, and center alignment for the crop or padding created by cover and contain.

Output

Output	Type	Description
Resized Image	File	The resized image, preserving the input name and MIME type.

Examples

Set width to 1200, leave height empty, and use pixels to make a 1200-pixel-wide image without changing its proportions.
Set width and height to 50 with percentage units to halve both dimensions.
Set 1080 by 1080 with cover to create a square crop, or contain to retain the whole source inside a square canvas.

If both width and height are empty, the action has no target size. Provide at least one dimension for predictable output.
