Frequently Asked Questions
How does the AI upscaling work?expand_more
Our upscaler uses multi-step processing where the image is gradually enlarged in 2x increments with smart unsharp mask sharpening applied between each step. This produces significantly better results than a single resize operation, preserving edges and enhancing details.
What enhancement modes are available?expand_more
Standard mode does a clean multi-step resize. Sharp mode adds unsharp mask sharpening between steps and a final pass. Ultra mode applies two-pass sharpening with different radii for both coarse and fine detail enhancement.
Are my images uploaded to any server?expand_more
No. All processing happens 100% in your browser using the HTML5 Canvas API. Your images never leave your device.
What is the maximum upscale factor?expand_more
You can upscale up to 8x using the custom slider. For best quality, 2x-4x is recommended. Higher factors work best with the Ultra enhancement mode.
What is the slider comparison mode?expand_more
Slider mode overlays the original and upscaled images. Move your mouse or finger left/right to reveal each version, making it easy to see exactly what the upscaling improved.
