How to Upscale MidJourney Images to 4K/8K Resolutions

The default resolution of MidJourney generated image is 1024x1024 (model v5 and Niji5). Version 4 and Niji 4 produce a base image at 512x512, and you can click the U button to upscale it to 1024x1024. Either way, the 1024x1024 resolution (or its 1MP counterparts at other aspect ratios) is not enough for a high-quality display. So how to upscale MidJourney images? How to increase its image resolution to the max for printing?

No matter you are planning to share a crystal clear high-res image with the clients, print out the art as posters and large wall art, or display it on UHD 4K and 8K TVs, you can follow our step-by-step guidance below to upscale MidJourney images.

How to Upscale MidJourney Images to Max Resolution

After you have prepared the AI-generated art from MidJourney, you can save it to the local drive on your computer and use AI Image Upscaler to increase the resolution.

Considering the ease of use, result image quality and feature set, we will use VideoProc Converter AI as a demonstration here to upscale MidJourney pictures.

Step 1. Download and install VideoProc Converter AI on your computer.

Step 2. Go to the Super Resolution feature from the main UI. It is the image upscaler we will be using for MidJourney pictures.

Super Resolution in VideoProc works for videos and images, and it also supports batch tasks for a smooth workflow.

Popular image formats such as PNG, JPEG, WebP, PBM, XBM, PGM, PPM, XPM and GIF are supported to import. You can also directly drag a folder to process.

Step 3. Choose the image type so that the upscaler can use a suitable AI model to upscale your MidJourney image.

• Opt for the Reality type if your MidJourney images are depicting (or imitating) real-world scenes and characters.
• Opt for the Anime type if your MidJourney images are anime, cartoon, comic styles, or other 2D-illustrations.

If you are not sure which Type to choose, you can experiment with it, and check the realtime priview to decide which one performs better.

Sometimes you need to enlarge the window of the application to see more clearly, or export the image to compare.

You can also switch the previewing modes between single or dual modes.

Step 4. Choose 2X, 3X or 4X upscaling, depending on your specific needs.

If your source image is 1024x1024, choosing 2X will upscale your image to 2048x2048, 3X will be 3072x3072, and 4X will be 4096x4096.

If your source image is 896x1344, 4X parameter will upscale your image to 3584x5376. That's about 20 megapixels, which is more than enough for you to print high-quality wall arts and posters, or share on 4K displays.

Note 1: If you want to have 8K photos, then after exporting the 4096x4096 image, you can re-add it into the Super Resolution tool in VideoProc Converter AI. Now you will notice you can select 2X, while 3X and 4X are greyed out. For 2X option, the 4096x4096 will become 8192x8192 8K resolution, that's a 67-megapixel image. As mentioned above, 20-megapixel images are already enough for large poster printing, and in most cases, you won't need resolutions higher than 8K.

Note 2: VideoProc Converter AI makes it efficient for you to batch upscaling images and videos. You can drag and drop the files, tweak the settings, and right-click on that image to "Apply Settings to All". For instance, if you prefer to upscale the image 3X, choose it and then hit "Apply Settings to All".

Step 5. Adjust export settings and hit Run to finish upscaling the MidJourney image.

This image upscaler supports both PNG and JPEG format. For the best quality, keep the Image Quality at 100% upon exporting.

Below is the demonstration of the source AI art vs upscaled images.

How to Upscale MidJourney Image with 2X and 4X Upscaler

Previously, after using the imagine command, you will have a grid of 4 MidJourney images. Then you can press U1/U2/U3/U4 to separate the selected image from the grid. The separated image will be 1024x1024 (or other resolution of different aspect ratio around the 1MP size).

Now MidJourney introduced the 2X and 4X upscaler immediately after you picking 1 out of the 4 initial images. If your base image is in 1:1 aspect ratio, then:

• For the Upscale (2x) button: it delivers a 2048x2048 image
• For the Upscale (4x) button: it delivers a 4096x4096 image

Note:

1. Using the 2X and 4X upscaler will count against your GPU time.
2. Both upscalers are only available for the Fast Mode. If you run out of the Fast Mode quota, you won't be able to upscale MidJourney Images natively inside its Discord service.
3. If you are using the pan tool or the tile parameter (-- tile) to create a seamless pattern, you cannot use the 2X and 4X upscaler.

If you are new to MidJourney, follow the steps bellow to generate AI images and upscale MidJourney images to the desired resolution.

Step 1. Click the official invitation link to join MidJourney on Discord.

https://discord.com/invite/midjourney

Step 2. Choose a plan that suits your needs.

Note:

As mentioned before, Fast GPU time directly decides whether you can use the 2X and the 4X upscaler. If the 3.3 hour per month quota for the Basic Plan isn't enough for you, you may need to consider upgrading the plan.

Step 3. Type /imagine and write the prompts.

• You can join the MidJourney channel to send or prompts.
• Or you can click the MidJourney bot to send the prompts directly.
• Or more preferably you can create your own server, and invite the MidJourney Bot to your server.

If you have no idea what prompt to write, you can type /describe and paste a link of the image that you want to imitate. Then use the description offered by the bot with the /imagine command.

Step 4. Choose 1 out of the 4 AI-generated images by clicking U1 or U2/U3/U4.

Step 5. Click the Upscale 2X or Upscale 4X button to increase the resolution of MidJourney image.

Once you are happy with the results, right-click to save the image to the local drive.

If you run out of the Fast GPU time, the upscaler inside MidJourney will stop working. Then you can consider using the dedicated AI Image Upscaler introduced in Method 1 above, as it won't impose the GPU time limitation on you.

Note: MidJourney Alpha have launched outside Discord. The alpha version is available at alpha.midjourney.com. However, currently, only users who have generated over 10,000 images can access the Alpha version. The upscaler in MidJourney Alpha is 2X and 4X, the same as the Discord version.

Tips: Upscale MidJourney Image to High-Quality Print Size

For many users searching for Image Upscaler for MidJourney, their ultimate goal is to print out MidJourney arts with high quality. For your convenience, below is a list of recommended print size for images, with corresponding megapixel value (MP) and resolution.

Depending on the different printing services that you may be using, the recommended dimensions can differ from one another. Still, as you can see from the following chart, the default 1024x1024 resolution from MidJourney fails short of delivering ideal results for most occasions.

MidJourney Official Recommendation for Image Print Size

The official image size document from MidJourney also noted that, since the default resolution is 1024x1024 pixels, and a quality print requires 300DPI, thus the recommended print size for a 1024x1024 image would be 3.4x3.4 inches.

That is far from ideal given the time and effort we put into generating a delicate MidJourney Art. Now with the AI image upscaler method demonstrated above, you can easily upscale Midjourney to higher resolutions for printing.

Common Midjourney Aspect Ratios

--ar 1:1 Default aspect ratio.
--ar 5:4 Common frame and print ratio.
--ar 3:2 Common in print photography.
--ar 7:4 Close to HD TV screens and smartphone screens.
and their vertical versions: 4:5, 2:3, 4:7
