Frequently Asked Questions
How does Image Upscaler & Enhancer increase resolution?
The tool uses high-quality HTML5 Canvas bicubic interpolation to scale image dimensions 2x or 4x, combined with an optional unsharp contrast enhancement pass to sharpen edge definition. It does not fabricate or hallucinate new pixels.
Can this tool recover lost details or blur from low-resolution photos?
No. Canvas-based interpolation enlarges existing pixels and enhances edge contrast, but cannot reconstruct detail or focus that was not present in the original photograph.
Are my photos uploaded to any server?
No. All scaling and sharpening operations run 100% locally inside your web browser using HTML5 Canvas technology for complete privacy.
