Upscale image to 8K: what the 8K setting does
8K here means 7680 pixels on the long side of your photo.
This page enlarges a photo until its long side is 7680 pixels. An AI model runs inside your browser and draws in the extra pixels, so edges and textures are rebuilt instead of just stretched.
The size follows your photo's shape. A 3:4 portrait comes out around 5760 x 7680, not 7680 x 4320. Pick 4K (3840 px) when you want a lighter file or a photo is too small for 8K.
JPG, PNG and WebP up to 20 MB go in. PNG keeps transparency and is the default; JPG makes a much smaller file. A very small photo is enlarged in two passes, a larger one in one.
The result is AI output, so zoom in and compare it with the original before you use it.

Browser 8K upscaler vs upload sites vs a plain resize
Pick by where the photo goes and what you need back.

Where an 8K upscale gets used
When you upscale image to 8K, these are the jobs where the extra pixels earn their file size.
Large prints and posters
A bigger pixel count gives a print shop more to work with. Check the 8K result at 100 percent before you send the order, and look at faces and small text first, because those are where an AI redraw shows.
8K and 4K displays
Wallpapers and slideshows for big screens need a matching file. Choose 8K for an 8K panel and 4K for a 4K one. A photo that is already 4K or bigger is refused at the 4K setting.
AI-generated art at 8K
Image generators often stop near 1 megapixel. Upscale a favorite output to get a version you can zoom into, then keep the small original next to it.
Product and listing photos
A larger master lets you crop in on a detail and still have a sharp image to export from. Save as JPG when the file goes to a web shop.
Scanned photos and documents
A small scan of a family print or a poster becomes a larger file for archiving or reprinting. Scratches and fading stay in the picture, since this page only enlarges.
Crop room for design work
Enlarge first, then crop to a banner or a thumbnail without running out of pixels. One 8K master can feed several crops.
