MarkItDown File Converter

Native file formats like PDF and DOCX contain heavy metadata, binary encoding, and formatting data that AI models must decode. This wastes context window tokens on structural noise rather than actual content. Clean Markdown removes all that overhead, letting the AI focus entirely on the meaning of your text — reducing token consumption by up to 60% on complex documents.

No. Files are processed in a temporary directory on the server and deleted immediately after conversion. Nothing is stored, logged, or retained. Your document never touches a database.

The current limit is 10MB per file. This covers the vast majority of business documents, presentations, and spreadsheets. For very large files, consider splitting them into sections before uploading.

Paste any public YouTube URL and MarkItDown will fetch the video's available transcript (auto-generated or manual captions) and format it as clean Markdown. This works best on videos that have captions enabled. Videos without any captions cannot be transcribed by this method.

The conversion engine runs on a cloud server that powers down automatically after periods of inactivity. When you're the first user in a while, the server needs 20–40 seconds to "wake up." Once running, all subsequent conversions are fast. You'll see a warning banner if this is happening.
