File conversion without memorizing five tools.

The problem

Converting a PDF, trimming a video and compressing an image usually means remembering three different command-line tools and their flags. I wanted one command that reads closer to the task.

What I built

• Plain commands such as omx convert report.pdf to markdown
• Local conversion for documents, images, audio and video
• Batch jobs, dry runs and JSON output for scripts
• Clear exit codes and tests across the file engines

Scanned PDFs are the exception

Normal conversions stay offline. Scanned PDFs do not have a usable text layer, so better extraction needs the opt-in --refine path and a Gemini key. The CLI says that plainly instead of pretending every PDF is the same.
