Everyone uploading PDFs is basically wasting their tokens. And Microsoft had a free solution for months. Every time you drop a PDF into Claude, it reads through broken formatting, unreadable images, and hidden junk, burning thousands of tokens before your first question and giving you worse answers. The fix is a free tool called Markitdown with over 128,000 GitHub stars. It converts PDFs, Word docs, PowerPoints, and Excel sheets into clean markdown. Claude was trained on markdown, so it understands the format natively, up to 70% fewer tokens and sharper responses. Markitdown has an MCP server you connect in one click inside Claude desktop, and every file converts automatically. Link is on your screen.
