Large PDF to Markdown

Large & scanned PDFs → AI-ready Markdown—free to try, no paywall first.

Upload text PDFs, mixed reports, and scanned pages. md.robinren.me classifies the file, extracts text or runs local OCR, and routes long jobs through a background pipeline with progress, cancel, and failed-page retry.

Convert a PDF

Large files welcome

PDFs can be classified up to 512 MB. Suitable files convert immediately; heavier scans use free local background conversion within current limits.

Scanned PDF OCR

Chinese and English local OCR handles image-only pages. You see page progress instead of waiting on a silent browser request.

AI-ready Markdown

Use the output for prompts, RAG preparation, Obsidian notes, Notion imports, and documentation without rebuilding a document pipeline.

Before you convert

AI-ready Markdown: inspectable text for prompts, RAG, and knowledge bases—full file plus page chunks when available.
Local by default: conversion runs on this server; cloud OCR is not used unless an explicit consent flow is shown.
Beta tip: start with non-sensitive files. Temporary results expire (about 24 hours on Free); you can delete jobs early.
