Enlarge JPG, PNG and WebP images by 2x, 4x, 8x or to a custom size. The image is resampled smoothly, which works well for modest enlargements of photos and graphics; it cannot recover detail that was never captured.
ToolzStack uses conventional resampling (canvas smoothing in the browser, bicubic on the server), similar to image editors' resize commands. Dedicated AI upscalers can reconstruct more texture at large scale factors; this tool is free and needs no installation.
