About this tool

Try 2× enlargement for small illustrations, thumbnails or low-resolution assets. The model generates an interpretation rather than recovered evidence, so check lettering and facial details in the result.

How to use

Upscale image

What this tool is for

Use local Real-ESRGAN inference to double image width and height; the verified model is cached after its first download and the page shows the current device limit.

How to use it

Check the input-pixel budget reported for this device, then download and cache the 2× model. Width and height are both doubled; inspect faces, lettering, and fine textures for model artefacts before using the result.

Results and next steps

Each selected source produces one result card with preview, pixel dimensions, format, and size. Download one file, selected files, or the complete ZIP.

Privacy and local processing

Processing runs in your browser. Source images are not uploaded by this tool.

Common questions

Why does a small file exceed the AI input limit?

AI memory use depends on pixels, not encoded bytes. The page reports this device's edge and pixel limits; doubling width and height creates four times as many pixels. Reduce the input if needed and inspect generated lettering and faces for artefacts.

Will a transparent PNG stay transparent after AI enlargement?

The current AI model produces opaque pixels and does not preserve the source alpha channel, even when saved as PNG. For a transparent logo or asset, use ordinary resizing with enlargement enabled and check the edges; it does not add AI-generated detail.

When should I use AI enlargement instead of ordinary resizing?

Ordinary resizing interpolates existing pixels and suits exact dimensions or transparent assets. This AI model estimates texture while doubling each dimension. It may alter lettering and faces, so do not use it to establish unclear source information as fact.
