If you have ever used Midjourney, you will know that Midjourney’s images are amazing in every aspects, except the small size. By default, the Midjourney produces images in 1024 x1024. This is too small to print on a poster, POD service, background, etc. Luckily, Midjourney’s upscalers can help increase the image size. In this article, we will show you how to upscale Midjourney images to 4K, 300 DPI, or higher resolution for print, design, advertisement, etc.

KeyTakeaways

  1. Upscaling Midjourney images will cost you lots of GPU minutes with 4X upscaler costing roughtly 3x more GPU minutes than 2x upscaler.
  2. Midjourney 6’s Subtle and Creative upscalers can only upscale images 2x to 2048P.
  3. Midjourney’s 4x upscaler is only available in Version 5.2

How to Use Midjourney Upscale 2x?

1. Generate an Image

Create an image using the /imagine command.

2. Select an Image

Look for the "U" button below each generated image in the grid. Use a U button to separate your selected image from the grid.

3. Select Upscale

Once isolated, a new set of buttons will appear, including "Upscale (Subtle)" and "Upscale (Creative)". Click on the Upscale (Subtle) or Upscale (Creative) button to upscale your image. Both upscalers will double the size of your Midjourney image to 2048 x 2048 pixels.

  • Upscale (Subtle): This option prioritizes maintaining the original style while doubling the image resolution.
  • Upscale (Creative): This option focuses on adding more detail and artistic flair during the upscaling process. While it can achieve a more visually-appealing result, it may introduce slight stylistic changes compared to the original image.

Limitations of Midjourney Upscalers

Midjourney upscalers, while offering image upscaling capabilities, is hindered by several limitations and bugs that hinder its overall user experience. The slow processing speed, particularly in Relax mode, coupled with details loss, excessive softness, and overly sharpening artifacts, make it less appealing for users seeking quick and high-quality results. Additionally, the lack of batch processing and multiple upscaling options further restricts its usability. 

1. Can’t Upscale Midjourney to 4K or Higher Resolutions

  1. how do I upscale an image to 4k using MJ6? I usually use 5.2 and theres a prompt that comes up for 4k upscale but it doesnt for version 6,
  2. How do I upscale a image to 4k resolution once I like the final result?

The current Midjourney V6 upscalers can only upscale images by 2x. If you want to use Midjourney 4x upscaler or upscale Midjourney images to 4K quality, you need to switch to V5.2. However, this means you'll sacrifice the newer features of V6.

2. The Upscaled Midjourney Images are Too Soft

  1. Seems like the upscales sometimes soften the image too much? Things like lace necklines end up a bit muddy.
  2. I feel that depending on the image it kinda softens it too much, epsecially with skin, it tends to lose realistic look in characters

Midjourney uspcalers, especially V6 Subtle upscaler, make the upscaled image look software and lose its sharpness. Sometimes, the upscaled image comes out too soft to extent it's not usable.

3. Detail Loss

  1. MJ does a good job in some respects but it really likes to smooth out finer details, which really ruins the vibe of the image, and sometimes makes photo quality renders into wax characters.
  2. Anybody have any tricks for getting better upscale results? Upscale often destroys details which kind of ruins the character of the image, which sucks.

Many users notice that a lot of details disappear from the original image after upscaling, such as the leaves, flowers, furs. Midjourney upscalers replace the finer details by simpler texture and lines. This destroy the characters, aesthatic value, and vibe of the image.

4. Original Image changed

  1. Is there a work around for upscaling on the alpha site where there is no change to the image
  2. there a way to upscale v6 images without MJ trying to alter the image (subtle/creative) ? I'm asking for something like v5.2's "x2" or "x4"

With Midjourney V6’s Subtle and Creative upscalers, too many details are changed and created. When someone is satisfied with an Midjourney image, the uspcaler changes the minor details and even stype. However, some users simply want a faithful upscaling, no "creative" stuff.

5. Blur, Noise, Pixelation

  1. I'm happy with result so I wanted to upscale it to get better resolution and hopefully more detail... but upscale result is astonishingly more blurry
  2. weird textures triggered when utilizing subtle upscale

Instead of upscaling Midjourney images to higher quality, the upscaled outputs introduce quality issues, such as blur, pixilation, and noise. On some images, there is a weird dotted canvas texture on the image.

6. Slow Speed

  1. Has anyone noticed that the Creative Upscale is taking a lot longer in the past few hours.. In relax mode it taking 15-20+ minutes. In Fast it's 1/3rd of that or less.
  2. Why does upscale take so long now?

Our tests and user feedback indicate that upscaling an Midjourney image takes approximately: 2 minutes for 2x upscaling and 4 minutes for 4x upscaling. However, if you choose to use the relax mode to save your fast GPU hours, the processing time may be significantly longer due to the queueing system.

7. High Price

Upscaling images in Midjouney consumes GPU time. The basic plan can upscale 33 images to 4K/month and 99 images to 2K/month. Besides, various factors will affect the specific amount of time, including the upscaling ratio, image resolution, and image complexity. Once these limits are reached, further upscaling will require additional GPU time or a subscription upgrade.

You may switch to the relax mode that prioritizes saving GPU time over processing speed. However, this mode significantly increases processing time.

8. Face Distortion

  1. im on V6 or when I upscale the face becomes distorted 
  2. i finally have my image, i upscale it and boom... its like MJ telling me to forget beauty and go for ugliness

In some cases, the face in an upscaled Midjourney image is distorted, destroyed, blurry, or otherwise becomes ugly.

9. Midjourney Upscalers can’t Upscale Local Images

  1. is there a way to take an uploaded image and simply upscale it using Midjourney?
  2. is it possible to take an image I've drawn, put it into MJ and ask it to upscale or improve it?

Midjourney upscalers can only handle images created on Discord. You can’t uploaded an image from local computer and simply upscale it using Midjourney.

10. Upscaling Errors

  1. Job with id xxxx not found when use upscale
  2. Can't upscale, always failed to process your command

While image upscaling in Midjourney is easy, it’s not necessarily smooth. Various errors may occur, including “can't upscale, always failed to process your command”, “job not found”, “Could not complete the job”, etc.

FAQ

1. How to upscale Midjourney images to 300DPI print quality?

When upscaling an Midjourney image, check if there is a field labeled "DPI" in the upscaler. If not, you need to determine the appropriate pixel resolution for 300DPI. Decide on the final printed size (width and height) in inches: For example, let's say you want a print that's 8 inches wide and 10 inches tall.

  1. Multiply the desired width by 300: 8 inches * 300 dpi = 2400 pixels
  2. Multiply the desired height by 300. 10 inches * 300 dpi = 3000 pixels
  3. This gives you the pixel resolution needed for your desired print size at 300 dpi: Width: 2400 pixels, Height: 3000 pixels
2. Is there a way to upscale Midjourney images without altering an image?

If you upscale in Midjourney, then you can hardly get an upscaled image without change. Midjourney will optimize and alter the details more or less. Both Subtle and Creative upscale in Midjourney V6 will introduce noticeabl changes in the details. If you want to upscale faithfully to the original image, try a third-party upscaler like Aiarty Image Enhancer.

3. How can I use Midjourney's upscale for an uploaded image?

You can't. Midjourney currently doesn't offer the ability to upscale images directly through uploading them. Midjourney's upscaling feature is designed to work with images generated within the platform itself.

4. Can Midjourney upscale images to 4K?

Yes, you can use V5.2 to upscale images from 1024P to 4K quality.
