Upscale any image

An AI image upscaler enlarges a picture and fills in the detail a plain resize can't. Stretch a small photo in an editor and you get the same blur at a bigger size. An AI upscaler predicts the texture that should be there, the strands of hair, the weave of fabric, the edges of leaves, and draws it at the new resolution.

On Mage that job belongs to Image Enhancer. Upload one JPEG or PNG of up to 30MB, choose 2K, 4K or 6K, and it upscales and refines the image in one pass. It works on photos and AI images alike, which makes it the last step for anything you made on Mage and want to print, crop or show full screen.

Two more tools sit beside it. Skin Enhancer restores natural skin texture in portraits that came out waxy or over-smoothed, at 2K or 4K. Refine makes focused fixes with presets such as Fix Eyes, Fix Hands and Add Detail, or with your own instruction. Use them before upscaling, so the enhancer enlarges the corrected image.

Pick the resolution for where the image will end up, not the biggest number. A 2K image is roughly 2,000 pixels on its long side, plenty for social posts, websites and phone screens. 4K covers large monitors, TVs and presentations. 6K is for prints, posters and images you plan to crop hard, where every extra pixel turns into usable detail.

Bigger outputs take longer to make and to download, and on a paid plan they sit on different tiers: Enhance runs unlimited at 2K on Pro, 4K on Pro Plus and 6K on Max. Every size is also available with Gems on any plan, so you can try 6K once without changing plans.

• 2K for social posts and the web.
• 4K for large screens and slides.
• 6K for print and heavy crops.
• Upscale last, after edits and fixes.
• Start from the best source you have; a sharper input gives a sharper output.

An upscaler enlarges everything, mistakes included. A sixth finger or a smudged eye becomes a bigger, sharper sixth finger. So make repairs at the original size: run Refine with Fix Hands or Fix Eyes, or mask the problem in Inpaint and describe the fix, then send the corrected image to Image Enhancer.

Portraits deserve one more pass. AI portraits often come out airbrushed, and upscaling makes the plastic look more obvious. Skin Enhancer restores realistic texture first, at a strength of Low, Medium or High. For faded or damaged photos, follow the full workflow in the AI photo restoration guide.

If you are creating a new image rather than rescuing an old one, you can often skip the upscale. Mango 3S generates at up to 3K, and Mango 2 and Nano Banana 2.1 at up to 4K, so a poster or a wallpaper can come out of the generator at full size. Upscaling is then for going further, to 6K, or for images from a model that stops at 2K.

Video has its own tool. To sharpen a clip instead of a still, use Video Enhancer, which upscales videos of up to 10 seconds to 720p or 1080p. The AI video enhancer guide covers it.
