Let’s Enhance is an amazing free online service that is said to use neural networks to upscale JPEG images by a factor of 4. The tool analyzes the image and ‘hallucinates’ missing details to improve the quality of the final image.
- Fix the JPEG.Got only JPEG original? All blocky noise is detected and removed automatically
- Upscale 4x. Boost resolution 4x times, keep edges and features sharp and crisp.
- Add missing details. Neural network hallucinates missing details to make image look natural.
