This uses smooth, high-quality interpolation, not AI super-resolution. It enlarges cleanly but won’t invent detail that isn’t in the original.

Preguntas frecuentes
Is this AI upscaling?
No, and we'd rather say so plainly than oversell it: this uses progressive high-quality canvas interpolation, which enlarges cleanly with less blur than a single naive resize, but it doesn't invent new detail the way an AI super-resolution model can. For most resizing needs (printing, display, mockups) that's exactly what you want; for recovering fine detail from a very low-resolution source, dedicated AI tools will do better.
What's the largest factor I can use?
Up to 4x in one pass. For more, upscale the result again afterward.
Is my image uploaded anywhere?
No, upscaling happens entirely in your browser using the Canvas API.
