What is a PNG upscaler?

A PNG upscaler increases width and height while AI rebuilds detail so the enlarged file looks sharper than simple stretch-resize. Useful when you need a bigger PNG for print, zoom, or high-DPI screens.

2× vs 4× upscale — which to pick?

Use 2× for a moderate boost (social, web, product zooms). Use 4× when you need much larger output for posters or crops. Extremely tiny sources have less detail to recover at 4×.

Does it keep PNG transparency?

Inputs with alpha (transparent PNGs) are best kept as PNG on the way in. Results with transparency are returned as PNG when the upscaler preserves the alpha channel; otherwise you may get a solid-background JPEG.

Is the PNG upscaler free?

Yes. Free with no signup, credits, or watermark. Upscale in any modern browser on desktop or mobile — nothing to install.
