4K Image Upscaler
Choose an image and send it to Manus with a prompt for 4K, 4096 px on the longest edge. Manus upscales it in a new task. After that, you can keep going in the same task, for example to turn the 4K image into a poster.
What a 4K image means on this page
4K here is a pixel size. It tells you how large the result is, not how sharp it looks.
How to upscale an image to 4K
Three steps on your phone or your computer. The upscale runs in a Manus task.
What to do after you upscale
A 4K image is often the start of a bigger job. Pick a next step, and the card fills the prompt box above. Each prompt upscales your image first.

Frequently asked questions
What does 4K mean in this 4K image upscaler?
On this page, 4K means 4096 px on the longest edge. The prompt asks Manus for that size and for the shape of your image, not for a 3840 × 2160 video frame.
What size will my 4K image be?
The prompt asks for 4096 px on the longest edge, and the other edge depends on the shape of your image. Check the exact width and height of the result file in the task before you use it.
Does upscaling to 4K add real detail?
No tool can bring back detail that was never in the original. Upscaling gives you more pixels, and how sharp the result looks depends on the source image. Check faces, text, and small details before you use it.
Which image formats can I use?
Choose an image file that your browser can open. If the page cannot read a file, it tells you, and you can choose another one.
Do I need to sign in?
You can choose an image and read the prompt without signing in. To send them, sign in or create an account on the web. The page keeps your image and prompt on this device while you sign in, then Manus starts the task.
Is the 4K image upscaler free?
Tasks in Manus use credits. You can check credit options on the Pricing page.
Where can I find my 4K image later?
The task stays in your Manus task list. Open it to see the reply and download the image again.
What else can Manus do after the upscale?
You can keep going in the same task. For example, you can ask Manus to turn the 4K image into a poster. The cards under “What to do after you upscale” fill the prompt box with a prompt for a poster, a slide deck, a one-page website, or a cut-out with a transparent background.
