Increase the resolution
Drop a picture and choose how many times as large; the new pixels are drawn by a model.

The new detail is made up by a model from what pictures usually look like; it is never recovered from the picture. Do not use an enlarged picture as evidence of what was there.

Questions people ask
- Does a higher resolution make it sharper?
- More pixels let it print or show larger; the model adds plausible detail to fill them, which looks sharper but is made up.
- Is my picture uploaded?
- No. Real-ESRGAN runs in your browser from this site's own files, on your graphics where they are offered and in WebAssembly otherwise; nothing is sent.
- Why does it take a while?
- The picture is enlarged in parts of 128 pixels, each through the model; on WebAssembly a megapixel takes a minute or two, and the page says how many parts are done.
