Frequently Asked Questions
When should I use AI Image Upscaler vs a photo enhancer?
Use this upscaler for logos, icons, and flat graphics: a 256px logo becomes a crisp 1024px asset with clean edges. For photographs of faces, prefer a true AI-reconstruction enhancer — interpolation sharpens photos but cannot invent missing facial detail.
Are my images uploaded when upscaling?
No — upscaling runs locally in your browser with Canvas processing, so pixels never leave your device. Only the final file save passes through the download quota (signed-in free: 2 Pro downloads a day; Pro unlimited).
How do Pro download limits apply here?
Processing has no per-use cap and runs local; only saving counts. Anonymous visitors hit the Pro paywall (sign in to continue), signed-in free users save 2 Pro downloads a day, and Pro users save unlimited files up to 2 GB each.
