Extend a picture on any side, and FLUX.2 Klein 9B paints the new area with Pixaroma's PixaOutpaint LoRA. Your image goes back on top.

It holds the LoRA's trigger. Without it the new area can come out blank.</li><li>Crop out edges that confuse it. Noise, a frame line or a busy strip along the edge of your picture can make the new area come out strange. Drag the blue handles on Image Crop + Rotate + Pad inward to cut those edges off first.</li><li>Tight portraits: say what's below after the first sentence, like "the rest of her body".</li><li>A big pad can grow a second hand or face near your picture's edge. If it does, extend in two runs so your picture fills at least half the canvas each time.</li><li>The result is about 1.6 MP, whatever size your picture is. A 5000 px photo comes back about 1120 × 1488.</li><li>Leave Align at 1. A bigger Align adds pixels on the right and bottom, even on a side you didn't pad.</li><li>About 8 seconds a picture on an RTX 5090 once the models are loaded, 4 seconds for a new seed.</li></ul><h2 id="credits">Credits</h2>FLUX.2 [klein] 9B is by Black Forest Labs, under the FLUX Non-Commercial License: non-commercial use only.
