The Resize tool allows you to resize (resample) an image to make it larger or smaller. Don't forget that you can also do this when you export an image, which will apply to the exported image only.

Resize by absolute value This option lets you set the width and the height of the image in pixels directly. When Maintain aspect ratio is checked, either the width or the height will be calculated automatically.

Resize by percentage Enter a percentage to resize the image either up or down.

Resize by common dimensions Select an option from the drop-down list which contains common image sizes (in pixels).

Resampling method The calculation used to make the image larger or smaller. Some methods are slower, but result in higher quality results.
