Images

Larger pictures, made up honestly.

Make a photo or drawing two or four times as large with Real-ESRGAN on your device, part by part; the new detail is made up by the model.

An upscaler draws a larger picture that looks like yours.

Real-ESRGAN.

Two of Real-ESRGAN's compact models run on your device: one for photos, one for drawings and anime. They are made into ONNX by our own script from the published weights and served by this site.

Part by part.

The picture is enlarged in parts of 128 pixels, each read with a margin so they meet without a seam, and every part's result is checked before it is kept. Your graphics are used where they offer 16-bit shaders; WebAssembly otherwise.

Made up, not recovered.

The new detail is what the model expects pictures to look like, not what was there: never use an enlarged picture as evidence.
