How to use it
Choose an image, select smooth 2× or 4× WebP enlargement or AI 2× PNG enhancement for a small image, then review and download it.
What to check
AI enhancement supports up to 256 pixels per side and 32,768 pixels total; the first run downloads a small model. It predicts detail that may be inaccurate. Smooth interpolation handles larger images but cannot recover missing detail.
Review the result before using it in a published page, application, or agent configuration.
Quick answers
Frequently asked questions
What is the difference between the two image enlargement modes?
Smooth enlargement uses browser interpolation to make a 2× or 4× WebP. AI detail enhancement uses a local model to predict a 2× PNG from a small image. Review invented or distorted details before using it.
Which images can AI detail enhancement process?
The local model accepts images up to 256 pixels per side and 32,768 input pixels total. Choose smooth interpolation for larger images. The first AI run downloads model files and needs available browser memory.
