What is lynchtmlconv.exe?
lynchtmlconv.exe is the executable for Lynch HTML Converter, a desktop utility that batch-processes HTML, CSS, and JavaScript assets for optimized website delivery. It runs as a multi-process worker pool to parallelize conversions.
The converter uses a manager process to spawn worker threads for each file/entity, enabling parallel parsing, minification, and asset inlining while keeping tasks isolated from the host system.
Quick Fact: Lynch HTML Converter pioneered multi-process batching in 2012, allowing safe parallel conversions with sandboxed workers.
Types of Lynch HTML Converter Processes
- Manager Process: Orchestrates batch jobs and coordinates workers
- Worker Process: Per-file or per-batch conversion tasks
- I/O Service: Handles reading/writing assets to disk
- Plugin Process: Runs optional plugins for custom transformations
- Cache/Temp Cleaner: Manages temporary data and cache cleanup
- Scheduler: Executes scheduled/watch-folder conversions
