Overview
Description

MinerU is a high-accuracy document parsing engine that converts PDF, DOCX, PPTX, XLSX, images, and web pages into structured Markdown/JSON. It features a VLM+OCR dual engine, supporting 109 languages, and native integration with LangChain, Dify, and FastGPT. The engine can handle scanned documents, handwriting, multi-column layouts, and cross-page table merging, with output following human reading order and automatic header/footer removal.

PDFgear is a free PDF toolkit covering editing, format conversion, annotation, OCR, and digital signatures, available as desktop apps, mobile apps, a Chrome extension, and online tools. Unlike many PDF utilities that gate core features behind a paywall, PDFgear offers its editing and conversion tools at no cost and without requiring account registration. The app includes built-in AI chat functionality for summarizing documents and extracting information, batch conversion between PDF, Word, Excel, PowerPoint, and image formats, and OCR that extracts text from scanned documents in more than 30 languages. A companion product, eSignGear, adds free entry-level e-signature capabilities.
