How to upscale Midjourney images

01

Upload your image

Drag in a JPG, PNG, or WebP file, or click to browse. There are sample renders if you just want to test it. No account needed.
02

Pick the upscale factor

2x doubles each dimension, which covers most screen and presentation use. 4x takes a 1024px Midjourney grid image to 4096px, enough for print.
03

Download the result

It takes about 15 seconds to upscale your image. Compare before and after with the slider, then download the full-resolution file. The first one is free, no signup.

So verwenden Sie den KI-Texturgenerator

Danach können Sie die KI-generierte Textur auf Ihr Design anwenden, wenn Sie es mit MyArchitectAI rendern.

That ceiling matters the moment your image leaves the screen. A2 print at reasonable DPI, a portfolio book, a competition board: all of them want more pixels than Midjourney will give you. And if the image wasn’t generated in Midjourney at all, the built-in upscaler won’t touch it. This tool picks up where Midjourney stops, with 2x or 4x on any image you upload.

Renders and concept art are a special case. Hard edges and glazing reflections are exactly what smears at low resolution, and simple bicubic interpolation can’t bring them back.

    SketchUp model

    Adds detail instead of stretching pixels

    The AI upscaler model was trained on of low- and high-resolution images, so it fills in texture and edge detail rather than averaging neighboring pixels. You can see the difference in things like grout lines and wood grain, which stay crisp instead of blurring out.
    MyArchitectAI app interface

    Generates a style-faithful output

    The upscaler sharpens what’s already there without repainting anything. Color and composition stay put. Your image comes back as a cleaner version of itself.
    AI rendered image

    Optimized for architecture and interior design

    MyArchitectAI's upscaler handles renders from SketchUp, Lumion, Enscape, and Twinmotion, plus anything straight out of Gemini. Hard geometry and linework stay intact instead of getting the “oil painting” softening that general-purpose upscalers apply.

    What people use it for

    Most Midjourney users who end up here fall into one of these situations.

    Client presentations and pitch decks

    A 1024px image looks soft on a 4K screen or when projected in a boardroom. Upscaling before you export the PDF means the renders hold up where it matters.

    Print portfolios and brochures

    A4 print at 300 DPI needs roughly 2480 × 3508px. A 1024px image printed that large looks pixelated. 4x upscaling closes that gap without a reshoot.

    Real estate listings

    Property portals penalize low-resolution photos in their ranking. An upscaled interior or exterior render reads better than the same image at 1K, especially on listing detail pages.

    Competition boards

    Architecture competitions usually specify minimum image sizes. If your Midjourney renders came out at 1K, upscaling to 4K before compositing into the board avoids quality mismatches.

    Social media and editorial

    Instagram, Behance, and design publications prefer images at 2048px or wider. Upscaling your Midjourney images means it fills the frame instead of getting centered with white bars.

    Pre-press and signage

    Banners and site hoardings print at low DPI but at very large sizes, so the pixel count still needs to be high. 4x from 1K covers most mid-size signage.

    Frequently asked questions

    How do I upscale in Midjourney?
    Inside Midjourney: in v7, pick an image from the grid (U1 to U4), then choose Upscale (Subtle) to keep the look or Upscale (Creative) to add detail. Both double the resolution and top out at 2048px. In v8.1 those options are gone; you add --hd to generate at 2048px directly. To go past 2048px, you need an external upscaler like this one.
    Can Midjourney upscale an existing image?
    No. Midjourney’s upscaler only works on images generated inside Midjourney; there’s no way to upload a photo or an old render and upscale it there. The Editor accepts uploads for editing, but not for upscaling. That’s the exact gap this tool covers: upload any image and take it to 4K.
    What’s the best way to upscale Midjourney images?
    Get as many real pixels as you can from Midjourney first: the built-in upscale in v7 or --hd in v8.1 takes you to 2048px. Then run 2x here to reach 4096px. If all you have is a 1024px grid image, 4x gets you to the same place in one step, though starting from 2048px keeps a bit more genuine detail.
    Can Midjourney edit an existing image?
    Yes. The Midjourney Editor accepts uploaded images and can inpaint (erase a region and regenerate it), retexture materials and lighting, and make prompt-based edits. What it can’t do is upscale an upload; for that you’re back to an external tool.
    Can Midjourney extend an existing image?
    Yes. Pan and Zoom Out in the Editor extend the canvas on both generated and uploaded images, out to about 2x. One caveat: extended results can come back at lower resolution than the source, so an outpainted image is often a good candidate for upscaling right after.
    Can I upscale Midjourney videos?
    Not here; this tool is image-only. Midjourney’s video model generates 5-second clips at 480p, or 720p on higher plans, and there’s no native video upscaler yet. Most people run exported clips through a desktop video upscaler. If you just need one sharp frame, export a still and upscale it here.
    How can I improve Midjourney image quality?
    At generation time, use --hd in v8.1 (or the quality and stylize settings in v7) and pick the model version deliberately. After generation you have two options: upscaling adds resolution, and an enhancer improves the pixels you already have, things like sharpening, color, and compression artifacts. If your image is big enough but looks soft, try an AI enhancer instead of upscaling
    Is it really free?
    Your first upscale is free, full-resolution download included, with no account. Both 2x and 4x are available on that first use. After that you need a subscription. Most tools in this category make you sign up for credits before you see anything; here you can test the quality on your own image first.
    Can I use upscaled images commercially?
    From our side, yes. We claim no rights to anything you upload or download. Whether the underlying Midjourney image can be used commercially depends on your Midjourney plan and their terms of service, so check those for your case.
    Does it work on renders from SketchUp, Revit, or Lumion?
    Yes. It handles renders exported from SketchUp, Revit, Lumion, Enscape, or Twinmotion, plus Nano Banana and Stable Diffusion outputs. The page name aside, it isn’t limited to Midjourney images. Renders are actually one of the better use cases because hard geometry and glazing survive the process instead of getting softened.
