Limitations and notes

  • It is interpolation, not artificial intelligence: it adds no detail the photo does not have, it only makes it larger and smoother.
  • Sharpness boosts edges and can also emphasise noise or JPG artefacts; start low.
  • EXIF information (camera, location) is dropped when the new image is saved.

Frequently asked questions

Will it improve a blurry photo?

No. If the original is out of focus or heavily compressed, the enlarged version will be too. Really adding detail would need an AI model, which this tool does not use.
