Frequently Asked Questions

Is this PDF to Markdown tool free?

Yes, completely free. No hidden fees, no usage limits and no watermark. You can copy and download results freely.

Do I need to register or log in?

No. Open the page and drop in your PDF. No registration, login or personal information is required.

Are my PDF files uploaded to a server?

No. Everything runs locally in your browser. Files are never uploaded, and nothing is stored when you close the page - safe for sensitive documents.

How large can files be? Can I convert multiple files?

There are no artificial limits. You can select multiple PDFs and convert them in batch. The practical limit depends on browser memory; very large files can be split into smaller PDFs.

Can scanned or image-based PDFs be converted?

Yes. Built-in OCR automatically recognizes pages without a text layer. Chinese and English are supported; the language pack is downloaded once on first use.

Are headings, tables and multi-column layouts preserved?

Heading levels, ordered/unordered lists, code blocks, tables, TOC, links and bold/italic text are recognized, and two-column reading order is reconstructed. Very complex layouts may need light manual cleanup.

Is the output identical to the original?

Text content is kept intact; Markdown structure is inferred from layout heuristics, so it cannot guarantee 100% fidelity for every complex layout. You can freely edit the result after conversion.

Privacy

This is a pure front-end application: PDF parsing (pdf.js), OCR for scanned pages (Tesseract.js), layout analysis and Markdown generation all run inside your browser. Your files are never uploaded to any server and are never used for training or analysis. OCR language packs are downloaded on demand from public CDNs - they only contain recognition models, never your document content.
