Why it matters
Honest about what it does
This is Lanczos resampling with a measured sharpen. It does not invent detail, and any tool that claims to is guessing at what was there.
Good for line art and logos
Flat colour and clean edges enlarge well. A blurry photograph enlarges into a larger blurry photograph.
Nothing leaves the tab

Questions
How do I convert Image to PNG?

Is my Image file uploaded anywhere?
No. The image to png conversion runs in your browser, on your own device. The file never leaves it.
Is this AI?
No. It is a resampling filter. An AI upscaler hallucinates plausible detail, which is useful for a wallpaper and dangerous for a part you are about to cut.
