Is my PNG uploaded to a server?

No. The PNG is enlarged entirely in your browser: it never leaves your device, and there's no queue and no account.

How is this better than normal resizing?

Normal resizing spreads the same pixels over a larger area, which blurs. This tool redraws edges and fine texture at the new size — the before/after slider shows the difference on your own image.

What format is the result?

A PNG at the enlarged resolution. Your file's transparency is preserved through the enlargement.

How to upscale an image

Drop or pick your PNG image.
Choose 2× or 4× — the enlargement runs entirely on your device.
Compare against the original with the slider and save the result.

About upscaling

PNG is a lossless format with an alpha channel, pixel-perfect for logos, screenshots and line art. A PNG's transparency survives the enlargement: the result is delivered as a PNG with the alpha channel scaled to match.

Detail is rebuilt on your device as the image grows — edges and texture are redrawn instead of stretched, so small images come out crisp. Nothing is uploaded, and the full-size result is free. The first run downloads the upscaler (~9 MB) once; your browser keeps it for later visits.
