Frequently Asked Questions
How does the upscaler work?
It uses a canvas-based bicubic interpolation algorithm to enlarge your image with minimal quality loss. A future update will add AI super-resolution (Real-ESRGAN) for even better results.
Is the upscaler a Pro feature?
Yes. The Image Upscaler is available to Pro subscribers only.
Are my images uploaded to a server?
No. All processing happens entirely in your browser. Your images never leave your device.
What is the maximum upscale factor?
Currently 2× and 4×. Very large source images may take a few seconds to process.
