Frequently Asked Questions
Does upscaling improve image quality?
Browser-based upscaling uses bicubic interpolation with sharpening. It enlarges the image smoothly but cannot add detail that wasn't in the original. For best results, use on images that are slightly too small.
Is my image uploaded to a server?
No. All processing happens in your browser using the HTML5 Canvas API. Your images never leave your device.
What's the maximum input size?
Up to 10MB. Very large images upscaled 4x may be slow on older devices.
