This tool provides two super-resolution engines that analyze image content through intelligent algorithms, predict and generate high-resolution pixels for lossless image upscaling.
- Real-ESRGAN: Uses tile-based processing strategy with low memory usage
- All processing is done locally in the browser, images are not uploaded to servers
- Model only needs to be loaded once, subsequent processing is faster
