Why convert a PDF to Markdown for AI?
PDF files are built to freeze a fixed layout, which makes extraction hard for large language models (LLMs). Pasting them as-is often breaks sentences and destroys tables. Markdown translates your document into a tagged language that AIs like ChatGPT or Claude understand natively: headings, lists and tables are preserved, helping the model grasp the document's logical structure without wasting attention tokens.
100% local and private processing
The whole process runs in your browser thanks to pdf.js and Tesseract.js (WebAssembly). Not a single byte of your document is sent to a server: your contracts, quotes or internal documents stay private. It's ideal for sensitive files you do not want to upload to an online service.
Full privacy
No file goes through a server. The analysis happens in your browser's memory.
Tables & structure
Aligned columns are rebuilt into native Markdown tables, headings and lists included.
OCR for scans
Scanned pages or images are read by local OCR and converted into usable text.
Optimised for your prompts and agents
The result estimates the number of tokens consumed and lets you insert an AI instruction (summary, technical analysis, rewrite) directly at the top of the document. You then download a ZIP archive containing the Markdown file, the extracted images and a processing report, ready to drop into your favourite tool.
FAQ
Are my PDF files uploaded to a server?
No. The conversion runs entirely in your browser using the pdf.js and Tesseract.js libraries compiled to WebAssembly. Not a single byte of your document leaves your computer, which guarantees the privacy of your sensitive files.
Does the tool handle scanned or image-based PDFs?
Yes. When a page contains little or no selectable text, you can enable automatic OCR: Tesseract.js recognises the text directly from the rendered image, in French, English, Spanish, German or Italian.
Are tables converted correctly?
Our engine analyses the horizontal distances between text blocks to rebuild columns and produce native Markdown tables, including merged-cell handling. Technical sheets and pricing grids therefore stay readable.
What does the downloaded ZIP archive contain?
The ZIP bundles your final Markdown document, an "images" folder with the extracted illustrations and a JSON report detailing the number of pages, the OCR-processed pages and the estimated AI tokens.
