  • Fast Mode: Quick enhancement suitable for web use
  • Quality Mode: Better detail recovery with moderate processing time
  • Professional Mode: Maximum quality enhancement for professional applications

Can I enhance multiple images at once?

Yes. Select up to 10 images and they’ll be processed locally in sequence.

Are there any file size limits?

For smooth performance, keep single images under ~20MP pixels. JPG/PNG/WEBP are supported.

Are images stored anywhere?

No server storage. Download results directly. A future optional browser‑local cache may be offered.

Do I need an account or subscription?

No. It’s free, no account required.

Best Practices

For Best Results

  • Use images with good lighting when possible
