⚠️Newer: Krea 2 Rotate + Outpaint ⚠️
does everything this one does, plus turning. Use that one.
Extend a picture on any side, and Krea 2 paints the new area. Your image goes back on top of the result. Only the new area and a thin strip along the old edge change.
How to use it
Load your image.
Pick a ratio, or drag the orange handles out. The small button next to the ratios flips portrait and landscape.
Optional: describe the new area in What goes there.
Press Run.
What you need
AusBoss nodes 2.4.0 or newer. In ComfyUI-Manager, search "AusBoss". Already have them? Update first.

Tips
Keep each run's new area on one side to about half your picture's size, or pull both sides. Bigger one-sided pulls can paint a second copy of the scene. For more, run it again on the result.
Dark corners get extended. A vignette in your photo carries on into the new area. Crop the corners off first if you don't want that.
Keep Megapixels near 1.6. In my tests much bigger canvases came out with a darker, creased new area, and much smaller ones went blotchy.
Leave thinking on in the Write the prompt box. With it off, the caption can come back empty.
Leave Align at 1. A bigger Align adds pixels on the right and bottom, even on a side you didn't pad.

v1.1 fix (2026-09-30): dark and very colourful pictures no longer come back with a gray frame. The new area now starts from your picture's own colour, the seam blends over 32 px, and it opens with no ratio picked. v1.1 (2026-09-29): the padding follows your picture. v1.0 (2026-09-25): first release.

thanks for this! works perfectly!
edit because i'm dumbi keep seeing seams lines, i will figure an extra step to inpaint those lines area somehow. ty
thanks! i went hunting for seam lines on this one and ran a bunch of tests. the padded seams came out clean with the workflow as it ships (feather 64, 1.6 MP budget), but i found two things that do make lines:
- feather turned down: at 0 you get a hard line right along the seam, easiest to see in sky. keep it at 64
- an edge you didn't pad: the canvas rounds up to a multiple of 16 and the leftover few pixels land on the right or bottom edge. krea sometimes leaves that sliver unpainted, so you get a thin light line down that edge (my own sample does it on the right). for now drag that edge out a little too, 64 px was plenty in my tests
i'm writing a fix for that rounding in the nodes and will push it out with an updated workflow.
i also tried a low denoise pass over the seam as an extra step and it just swapped the line for a streak, so i'd try those first. if you still see lines, post one with your settings and i'll dig in
you were right, i changed father and multiple back to 64 - 16. now everything works perfectly. i'm gonna edit my comment now. thanks for your time!
It would be interesting to have a way to perform outpainting while keeping the original image completely unchanged in both size and resolution, and allowing the user to choose only the resolution of the newly generated outpainted area.
For example, imagine having a very large image, such as a real photograph, with a resolution well above 4 megapixels. Processing the entire image with an AI model may be difficult or inefficient because of its size.
Now imagine that I only want to extend the image slightly. I would be perfectly fine with the outpainted area having a lower resolution than the original image.
The idea would be to generate only the outpainted portion at a lower resolution, rather than processing or resizing the entire original image. The generated area could then be upscaled or stretched to match the dimensions of the original image and seamlessly composited onto it.
In other words, the original image would remain completely untouched at its native resolution, while only the newly generated outpainting would be produced at a lower, user-defined resolution and then scaled to fit the original image.
This could make outpainting much more practical for very large images, since the AI would only have to process the relatively small area being added rather than the entire high-resolution image.
here's a workflow to try for that: https://files.catbox.moe/0dsh2j.json. it's the Krea 2 outpaint one with Crop For Inpaint added, so a big photo keeps its full size and only the new part goes through krea at about 1.6 MP. load your picture, drag the pad edges and pick your models. on a 9.3 MP photo with 600 px added it came out 4352 x 2496, the original pixels are untouched except the last ~100 px at the seam and i couldn't see the join at full size. needs AusBoss 2.4.0. i only tried one photo and one seed, and the new area comes out a little softer than the original.
@AusBoss wow. amazing! thank you man
Really great stuff!
thank you!
i know this is only for outpainting source image, but what if i want to use the image like a normal image-to-image but with extended resolution let say the image is 1024x1024 and i want to get a horizontal image like 1920x1080. how do i set the workflow?
yeah you can. load your image, open exact padding in load image + pad and set left and right to 398 (that's 16:9 for a 1024x1024 picture). as published it keeps your picture exactly as it was and fills in the sides.
if you want krea to redraw the whole picture like a normal image to image, click the set latent noise mask and stitch inpaint nodes and hit ctrl+b to bypass both. keep denoise at 1: at 0.6 the new sides came out gray and muddy. bypassing only stitch inpaint isn't enough, it leaves a faint lighter band at the left seam.
the size follows the budget in load image + pad. at the default 1.6 you get 1680x944, set it to 2.07 for about 1920x1080 (it lands on 1920x1072). i tested one picture and one seed. the redraw stays close to your picture but it's not the original pixels.
