About Docling is an easy-to-use, self-contained, MIT-licensed open source toolkit for converting messy documents into structured data and simplifying downstream document and AI processing. It can parse many popular document formats into a unified and richly structured Docling Document, including PDF, DOCX, PPTX, XLSX, HTML, Markdown, AsciiDoc, CSV, images, audio, and scanned pages through an OCR engine of the user’s choice. Docling detects tables, formulas, reading order, chunks, bounding boxes, page headers and footers, pictures, captions, code, list items, paragraphs, cells, and document structure, making extracted content easier to process, search, and ingest into AI, RAG, and agentic systems. It can export parsed documents to JSON, text, Markdown, HTML, and Doctags, giving developers flexible outputs for pipelines and applications. Docling stores and traverses components according to reading order, partitions documents into bite-sized contiguous text chunks.

		Pros from Real Users Pros Good support, good features and easy to customize. The documentation is complete enough. Online demo is useful. Great SDK for viewing and editing PDFs. Also very interesting are the Office file viewing features, with client side conversion. Lots of possibilities to customize both style and functionality. Quick support provided by Omar Talaat and noe it's working perfectly. Many many thanks Omar for currently it's smoothly working for all config. Good application with a great support team. The product is stable without many error, bugs or downtime. The support team is one of the friendliest I have experienced. They also keep PSPDFKit updated with the newest technologies. It is very easy to use. Everything you need can be easily found in the documentation. Also the support team is very responsive and always happy to help with any problems. Great and easy to follow API, helpful guides and examples. I mostly deal with server side and had no problems with deploying it all on premises. I found their app/browser-based editing/working with PDF examples much much much better. Demos are top-notch and give you immediate picture of what you can do. PSPDFKit team, quickly, qualitatively and excellently helped with various questions related to document caching on iOS and Windows platforms. Fast, complete and pointing to the right solution. - UI and UX look clean and friendly. - Execution fast enough considering number of features. - Most complete web PDF features on market The product is very customizable and can be integrated with other custom applications. Support is very quick to reply to questions and provide answers.
