Hi HN, I built this because I was frustrated with having to download desktop tools just to upscale anime images.

  Key features:
  - 2x/4x/8x upscaling with the waifu2x algorithm
  - Noise reduction and face enhancement
  - Batch processing
  - Just added Japanese and Korean localization

Free tier available (20 credits on signup). Would love feedback on the UX or feature requests.
