ImageOptimizerBot

ImageOptimizerBot (@ImageOptimizerBot) uses "optimizer" rather than plain "compressor" in its name, which typically implies an attempt to balance visual quality against file size rather than simply cranking compression to the maximum. No detailed bio is published to confirm the specific technique used.

Usage follows the category standard: send an image, receive a processed file back. Without published benchmarks, it is impossible to say how it compares to the more concretely described ShrinkImage Bot elsewhere in this list, so a side-by-side test on the same source image is the only reliable way to judge the difference.

It is a reasonable bot to try when default compression settings elsewhere feel too aggressive, though this expectation is based on naming convention rather than confirmed behavior.
