: How do I extend an image by adding blur to sides? I need to make an image 1080 x 1920. But when I do, the image looks very distorted. Is there a way I can extend an image by adding this

These are steps with Gimp (or any other image processing software) to add a blurred border to an image.




Select all of the image (Select > All)
Shrink selection to desired size for paste below (7).
Feather selection to desired size for paste below (7).
Copy selection (Edit > Copy) to clipboard
Scale image to desired output size.
Blur the scaled image (here I just used a radial blur):





Paste the image from clipboard:






From the set of G'MIC plugins we also have a preset filter for a simple blurred frame (Frames > Frame [blur]).





In case the background of an image we want to extend is not blurred but has many details we can use the Heal Selection tool to fill the extended areas.


Crop-Extend source image to desired size:





Select the extended background to apply heal selection:





Add blur to hide the artifacts produced by heal selection:
