How In-Browser Image Upscaling Works
Standard image enlargement simply stretches pixels, resulting in blurry, pixelated edges. Our in-browser upscaling engine applies bicubic interpolation combined with an unsharp masking pass to detect high-frequency contours and boost local edge contrast.
This creates crisp, punchy visuals suitable for printing, website banners, and social media posting without sending your images to paid cloud APIs.
