8K image upscaler 67 MP in your photo's shape

Upscale a photo, screenshot or AI render to 8K for posters, banners and big prints. The AI rebuilds edges and texture as it enlarges and keeps your photo's shape — landscape, portrait or square.

How do you upscale an image to 8K?

To upscale an image to 8K, open Kenerate AI's image upscaler, choose Image Upscaler → 8K and press Upscale. The output keeps your photo's shape at about 67 megapixels: in our tests a 480 px landscape became 10923 × 6144, larger than an 8K UHD screen (7680 × 4320). Downloads have no watermark.

How it works

How to upscale an image to 8K

Three steps. Image Upscaler is already selected when you open the tool from this page — just switch the size to 8K.

Time needed
Steps
3 steps

  1. Step 1

    Upload the image

    Open the Kenerate upscaler from this page and add a JPG, PNG or WEBP up to 25 MB.

  2. Step 2

    Pick Image Upscaler → 8K

    The page opens the tool on Image Upscaler. Switch the size from 4K to 8K — the price is the same.

  3. Step 3

    Download your 8K file

    Check it at 100% and download PNG, JPG or WEBP with no watermark. Expect a big file: our 16:9 test was 13 MB as a JPG.

How big is an 8K image?

8K UHD is 7680 × 4320 pixels — about 33.2 megapixels, four times 4K. Photos are rarely exactly 16:9, so Kenerate keeps your photo's shape and gives you about 67 megapixels at the 8K setting. These are the real sizes from our 8K runs:

Input and output sizes from Kenerate 8K upscales (31 Oct 2026)

16:9 landscape480 × 27010923 × 614467.1 MP
4:5 portrait300 × 3757327 × 915967.1 MP

Both are larger than an 8K screen in each direction. At 300 ppi the landscape prints about 36 × 20 inches and the portrait about 24 × 30 inches.

Only need a screen-size result? Upscale to 4K is a quarter of the pixels and a much smaller file. For HD or Full HD, use the HD photo converter.

Engines

Which engine should you use for 8K?

Image Upscaler and Ultimate both have an 8K setting. Kenerate Upscale picks an exact size in megapixels, up to 128 MP.

8K upscaling questions

How do I upscale an image to 8K?

What resolution is 8K?

8K UHD — the TV standard in ITU-R BT.2020 — is 7680 × 4320 pixels, about 33.2 megapixels. That is four times the pixels of 4K UHD (3840 × 2160) and sixteen times Full HD.

How big is Kenerate's 8K output?

About 67 megapixels in your photo's own shape. In our tests a 480 × 270 landscape came out at 10923 × 6144 and a 300 × 375 portrait at 7327 × 9159 — both bigger than an 8K screen in each direction.

Is there a free 8K image upscaler?

You can start free: new accounts get free credits on sign-up, the 8K setting costs the same as 2K or 4K, and downloads have no watermark. After that, one-time credit packs that never expire — no subscription required.

Can I upscale a 4K image to 8K?

Yes. Upload the 4K image and pick 8K; a 3840 × 2160 frame needs exactly 2× to reach 7680 × 4320. Because Kenerate keeps your photo's shape and targets about 67 MP, the result is larger than 8K UHD.

Does upscaling to 8K add real detail?

It adds believable detail, not recovered detail. The AI rebuilds edges and texture as it enlarges, so a 100% crop looks far sharper than a normal resize — but on a tiny original, fine texture such as roof tiles or wood grain is invented, not what the camera saw.

When is 8K worth it instead of 4K?

For big prints, posters, banners and heavy cropping. At 300 ppi our 16:9 8K output prints about 36 × 20 inches; a 4K result covers wallpapers, slides and most social posts in a fraction of the file size.

Which engine should I use for 8K?

Image Upscaler is the simple, faithful choice for 8K. Ultimate also offers 8K with more fine detail for pro restoration. If you need an exact size, Kenerate Upscale lets you pick megapixels up to 128 MP.

What “8K” actually means

The 8K standard, why photo upscalers go bigger, what it means for print — and the honest limit.

On this page

What the 8K standard says

ITU-R BT.2020, the international UHDTV recommendation, defines two picture sizes: 3840 × 2160 and 7680 × 4320 [1]. The second is what TVs and monitors sell as 8K. It is a 16:9 screen format — photos in 3:2, 4:3 or 4:5 can't be exactly 7680 × 4320 without cropping.
