Upscale an image 2x or 4x

How it works

1. 1

   Upload the image

   JPG, PNG or WebP up to 10 MB. Transparent PNGs work too.

2. 2

   Pick 2x or 4x

   2x costs 1 credit, 4x costs 2. Both run in the same editor as everything else.

3. 3

   A larger image with reconstructed detail rather than stretched pixels.

Why an ordinary resize looks bad

Enlarging an image in a normal editor uses interpolation: to invent a new pixel it averages the ones around it. That is mathematically reasonable and visually terrible, because averaging is exactly what blurring is. Doubling an image's size this way gives you four times the pixels and no extra information.

Super-resolution takes a different approach. A model trained on millions of image pairs has learned what real detail looks like at higher resolution, so it reconstructs plausible texture — edges stay sharp, fabric keeps its weave, text stays legible.

It is reconstruction, not recovery. The model produces detail consistent with what it sees, and it is not reading information that was never captured. For photographs that distinction rarely matters. For anything forensic or evidential, it matters enormously and you should not use an upscaler at all.

When upscaling helps most

• Old photos and scans that are simply too small for modern screens.
• A product image you need at banner size but only have as a thumbnail.
• A logo you were sent as a small raster file with no vector original.
• Print work, where 300 DPI turns a screen-sized image into a postage stamp.
• Cutouts you want to use larger than the source photo allowed.

Where it will not save you

Heavy motion blur, severe JPG compression and badly out-of-focus shots do not improve. The model will happily produce a large, sharp-looking version of a blurry image, and the result usually looks synthetic rather than better.

Faces are the case to check. Super-resolution can subtly change facial features when there was not enough detail to work from, which is fine for a background extra and not fine for a portrait of someone you know.

Cutout first, then upscale

If you are doing both, remove the background before upscaling. Working on the smaller file is faster, and upscaling a clean cutout gives the model a clearer subject to reconstruct than upscaling a busy scene and cutting it out afterwards.

Transparent PNGs survive the upscale with their alpha intact, so the order costs you nothing.
