Frequently Asked Questions

Find answers to common questions

What is the difference between Fast and Quality mode?
Fast mode uses Canvas interpolation for instant upscaling. Quality mode applies multi-step upscaling with a sharpening filter for crisper, more detailed results.
When will AI mode be available?
AI mode uses the Real-ESRGAN deep learning model and is currently under development. It will be available in a future update.
Is my image uploaded to a server?
No. All image processing happens 100% in your browser. We use WebGPU/WASM technology to process everything locally.
What is the maximum upscale factor?
Currently 2x and 4x upscaling are supported. For 4x upscaling, we recommend using Quality mode for the best results.
