AI Image Upscaler

What 2× actually looks like

A whole-image slider cannot show an upscale: both halves get scaled to the same width on screen, so they look identical. This is a 100% crop of the same patch — the left comes from a 448 × 327 source, the right from the 896 × 654 output.

Will Image Upscaler work on your photo?

Match what is wrong with your image to what this tool can realistically do. Where it cannot help, the row says which tool can.

• A small photo you need bigger

  Good match

  The core case. Our sample went from 448 × 327 to 896 × 654 with the crust texture and flour on the loaf holding up instead of smearing.

• Line art, anime, screenshots

  Good match

  Edges and lettering keep their definition rather than turning into gradients, which is what plain resizing does.

• Already large and sharp

  Partial improvement

  You will get a file at twice the dimensions, but there is little latent detail to recover. Run it only when you actually need the pixel count.

• You need more than 2×

  Partial improvement

  Upload the output and run it again. Two passes give four times the original for four credits.

• A blurry face

  Use another tool

  Enlarging a blurry face enlarges the blur. Sharpen it first with Unblur Face

How to upscale an image to 4K (and when you don't need to)

Every run here is a true 2× in width and height, so getting to a target size is simple arithmetic. Work out how many passes you need before you upscale an image, and don't enlarge what is already big enough.

• Upscale image to 4K

  4K is 3840 × 2160. An image at least 1920 pixels wide reaches 4K width in one pass; one at least 960 pixels wide needs two. Smaller than that and even two passes fall short, so look for a larger original first.

• Upscale image for print

  Print needs about 300 pixels per inch for a sharp result. A 1,000-pixel image prints well at roughly 3 inches; one pass doubles that to about 7 inches, two passes to about 13. Posters viewed from a distance get away with less.

• Upscaling vs. resizing in an editor

  Resizing in a photo editor stretches the existing pixels, so edges blur and text turns into gradients. The upscaler predicts the missing detail instead, which is why lines, lettering and hair stay crisp at the larger size.

• When not to upscale

  Most recent phone photos are already 4,000 pixels or more across; upscaling them adds file size, not detail. The tool earns its keep on small web images, old digital photos, thumbnails, screenshots and AI images generated at 1K.

• Fix first, upscale last

  Blur, noise and damage are enlarged along with everything else. Restore or unblur first, then upscale the image as the final step.

Why Image Upscaler on AI Image Tools

• A real 2×, stated plainly

  The engine doubles width and height. We do not advertise 4× or 8× buttons that quietly deliver less.

• Edges stay crisp

  Lines, lettering and hair keep their definition instead of turning into blur, which is what plain resizing does.

• Fast enough for a whole folder

  Two to three seconds per image at two credits each, so a batch of product shots costs less than a coffee.

• Run it twice for 4×

  Need more? Upload the result again. Two passes give you four times the original size for four credits.

How to use Image Upscaler

1. Step 1

   Upload the image

   Photos, renders, illustrations and screenshots all work. Keep the source under 10 MB.

2. Step 2

   Upscale

   No factor to choose; every run is 2×.

3. Step 3

   Download, or go again

   Download the WebP, or upload the result for another 2× pass.

Get a better result

A few choices before you upload change the output more than any setting on this page.

• Start from the original file

  Enlarging a screenshot enlarges its compression blocks along with everything else. Find the earliest copy first.

• Repair before you enlarge

  Damage, blur and noise all get bigger too. Put the fix first and the upscale last. Photo Restoration

• Two passes for four times

  There is no 4× button because the engine does a real 2×. Running the result again is the honest way to get there, and it costs four credits.
