How processing works
A bounded binary search tests image quality. If quality alone is insufficient, dimensions step down before another search. Iterations and minimum quality are capped.
Supported formats
Input: JPG, PNG, WebP. Output: JPG for opaque images or WebP for transparent images.
Limitations
A tiny target may be impossible without severe quality loss. Results are kept as close as practical without an endless search.
