About aiimage4k

aiimage4k is an online AI image upscaler: upload an image, choose 2K or 4K, and get a larger, clearer version.

What it does

It upscales JPG, PNG and WebP images to 2K (within 2560 × 1440) or 4K (within 3840 × 2160), keeping the original aspect ratio and swapping width and height for portrait images. 4K is experimental, and actual dimensions depend on the AI provider.

How it works

Your image is sent to our configured AI image provider for enhancement, and the generated image is returned as delivered, without cropping or resizing. AI may change some details, so check the result before you use it, especially text, logos, faces and hands.

Which images it suits

It works best on slightly soft or small product photos, portraits and illustrations. Images with severe focus or motion blur, or text that is already unreadable, usually remain hard to use after upscaling.

Credits and cost

Upscaling requires a paid plan. Each 2K image costs 8 credits and each 4K image costs 18 credits. Credits are only used on success, and downloading the same result again is free.

Your images and privacy

Images created while signed in are available only to your account. Uploads and results expire after 24 hours and are deleted during the next scheduled cleanup. See the Privacy Policy for details.
