Fun Fact
Early digital image scaling in the 1980s relied on simple nearest-neighbor interpolation, which produced blocky visuals. Modern browsers now include advanced interpolation methods capable of producing significantly smoother results without specialized software.
Historical Context
Image upscaling has evolved from basic pixel duplication techniques in early raster graphics systems to sophisticated machine-learning methods used in professional imaging today. Browser-based upscaling tools represent a major shift toward decentralized computing, allowing users to perform advanced processing locally without reliance on cloud infrastructure.
