About PDFtoMD.im

A focused PDF to Markdown converter built around privacy, inspection, and honest output.

Why this project exists

PDF is excellent for preserving a page, but difficult to reuse as structured text. Copying from a report, paper, or manual often loses headings, joins columns in the wrong order, and flattens tables. Many online converters also require the complete document to be uploaded before a user can see the result.

PDFtoMD.im takes a different approach: the homepage is the converter, processing happens in the browser, and the original PDF remains beside the editable Markdown. The goal is to shorten document cleanup while keeping uncertain output easy to find and correct.

What the tool does

• Extracts selectable PDF text and uses position and font clues to rebuild reading lines.
• Runs local English OCR when a page appears to be a scan.
• Detects table-like rows and offers Markdown, HTML, CSV, and plain-text output.
• Removes repeated headers, footers, and page numbers when that option is enabled.
• Lets users compare, edit, preview, copy, and download the result.

What it does not do

PDFtoMD.im does not send a document to a generative AI model, promise perfect reading order, reconstruct original LaTeX, bypass passwords, or embed raster images in the Markdown. Complex columns, scans, formulas, and irregular tables still require source review.

How it works

The site is statically delivered. PDF.js reads and renders the file, a local layout layer turns positioned text into document blocks, and Tesseract.js provides optional OCR. The English OCR model and WebAssembly runtime are served from the same site and run in a browser worker. The result exists in page memory until it is cleared or the tab is reloaded.
