Prompt Optimizer & Minifier

Prompt Optimizer compresses large language model prompts to reduce token costs without changing their meaning. LLM APIs charge per token, and long prompts with markdown documentation, examples, and JSON schemas can consume a significant portion of your context window. This tool strips unnecessary whitespace, converts verbose JSON schemas to compact YAML, and removes markdown comments — reducing prompt size by 20-40% while preserving all semantic content.

The tool applies targeted transformations: markdown code block markers are removed, JSON structures are converted to YAML (saving syntax characters), comments and extra whitespace are stripped, and repeated patterns are collapsed. The output produces identical logical behavior when parsed — only the representation changes.
