Nothing about the picture changes: this is resolution, not a re-render. Best on older photos, phone shots and anything that came back soft.

How to upscale an image
- 1
Upload the image
Soft, small or over-compressed. The worse the source, the more there is to gain. This is the tool for the picture you wish were bigger.
- 2
Pick the model
Default is faithful and safe. Enhanced reconstructs more aggressively, which is what you want on genuinely low-resolution sources.
- 3
Upscale
The content is unchanged: same picture, same crop, more pixels. What comes back is up to 4K and lands in your files.
Image Upscale examples
A small or soft image goes in and the same picture comes back four times wider and four times taller. Nothing is redrawn: same crop, same faces, more detail.

What runs it
AuraSR
Every run goes through AuraSR, an upscaler built for one job: a fixed 4x enlargement that adds detail without changing what is in the picture.
Two checkpoints, one price
Default stays faithful to the source. Enhanced rebuilds detail more aggressively, which helps on tiny or heavily compressed files. Both cost the same, so you can run each and keep the better one.
Nothing to set up
Upload a PNG, JPG or WEBP and press the button. There is no prompt and no scale to pick, and the result lands in your files ready to download.
What people use it for
Upscale AI art for print
A 1024 pixel render from an image model comes back 4096 pixels wide, which is enough for a poster or a 4K wallpaper.
Rescue old and phone photos
Scans, screenshots and photos that were saved small get the pixels back for a frame, a slideshow or a new crop.
Product and listing images
Supplier photos that arrive at web size can be enlarged for zoom views and banners without a reshoot.
Finish an edit
Expand, inpaint or restyle a picture first, then upscale the finished frame as the last step so no detail is wasted.
What it costs
One upscale costs 3 credits, whichever checkpoint you pick. The $10 Basic plan (500 credits a month) covers 166 upscales, and Starter's 1,200 monthly credits cover 400.

Image Upscale: questions and answers
›Can I upscale AI art or a Midjourney image to 4K?
Yes, as long as you have the rights to the image. Any PNG, JPG or WEBP works, and because every run is a 4x enlargement, a 1024 pixel render comes back at 4096 pixels on that side.
›Do upscaled images have a watermark, and can I use them commercially?
No watermark, on any plan. Kinoseed's terms say you keep ownership of what you upload and of the outputs you generate, subject to the terms of the underlying model providers, so you need the rights to the image you upscale.
›How much does the AI image upscaler enlarge a photo?
Every run enlarges the image 4x using AuraSR. The content is unchanged: same picture, same crop, more pixels.
›What does the image upscaler cost?
Generating starts with a plan from $10 a month (500 credits a month). Each upscale costs 3 credits, so the $10 Basic plan (500 credits a month) covers 166 upscales.
›What is the difference between Default and Enhanced?
They are two checkpoints of the same upscaler. Default is faithful and safe, while Enhanced reconstructs detail more aggressively, which helps on genuinely low-resolution sources. Both cost the same, so you can try each and compare.
›What file formats are supported?
You can upload PNG, JPG or WEBP. Soft, small or over-compressed images are where upscaling makes the biggest difference.
›Will upscaling change my photo?
No. This is resolution, not a re-render, so faces, text and composition stay as they were. It sharpens and fills in detail at the larger size.
