Tiled Upscale 🆎
Sets the size of the finished picture in megapixels and cuts your picture into tiles a model can redraw one at a time. A picture that fits in one tile stays whole. Send the tiles through your sampler, then into Tiled Upscale Stitch 🆎 with the stitcher. A small picture is not redrawn far past the detail it has: it is redrawn at most max_growth times its own megapixels and enlarged the plain way from there. The report says what was done with your picture.

Inputs (7)
| Name | Type | Default | Description |
|---|---|---|---|
| image | IMAGE | The picture to enlarge and cut into tiles. | |
| megapixels | FLOAT | 4.000–64 | Size of the finished picture, in megapixels. 0 keeps the picture's own size. |
| upscale_modelopt | UPSCALE_MODEL | Optional. Enlarges the picture with an upscale model before it is cut into tiles. Unplugged, it is enlarged the plain way (lanczos). | |
| tile_megapixelsopt | FLOAT | 2.000.25–16 | The most your model redraws at once. A picture up to about this size stays in one tile. 2 suits Qwen Image 2.1 and Krea 2; use 1 for SDXL. |
| overlapopt | INT | 1280–1024 | How many pixels neighbouring tiles share. The join is blended across this strip. |
| multipleopt | INT | 321–256 | Every tile's width and height is a multiple of this. 32 works with every model tried; Qwen Image 2.1 needs it. |
| max_growthopt | FLOAT | 8.01–64 | A small picture is redrawn at no more than this many times its own megapixels, and enlarged the plain way from there. Raise it to redraw a tiny picture at a big size anyway. |
