who switched
The workflow changed; the checks still matter
People who once resized images in desktop editors can now consider browser-based services instead. That makes an image upscaler easier to find and compare, but it does not make access terms interchangeable. Someone preparing a presentation image may only need a modest improvement; someone enlarging an archival photo may care more about faithful detail than file dimensions.
For either person, the sensible approach is to inspect the current service terms, try an appropriate image if those terms permit it, and assess the exported result. Imageupscaler offers guidance on that decision, not a blanket promise about another provider's pricing, availability, or treatment of uploaded files.
