Upscale a renderor room phototo 4K

Upload a render or a photo and pick 1K, 2K or 4K. The MeltFlex image model is asked for the same picture again at that size in a single call, with one fixed instruction: keep the room, furniture, materials, colours, lighting and camera exactly as they are and only increase the resolution.

4K for print, presentation boards and anything shown on a large screen at full size: a 16:9 picture comes back 5504 by 3072, which prints 46 cm (18 in) wide at 300 dpi. 2K is 2752 wide, enough for social media, a website hero and email, and the file is a quarter of the size.

MeltFlex re-renders it, so it is not a pixel-for-pixel copy. Measured on 100 percent crops of the same renders, it held the composition, the materials, the marble veining and even the lettering on a wall poster, but a small object can shift slightly and a fabric pattern can be redrawn.

Uploads go in at up to 4096 pixels on the long side. MeltFlex always returns its 4K frame in your picture's aspect, 5504 by 3072 at 16:9 and 4096 by 4096 square, about 16 megapixels, however large the input was.
