pdfminer.six review
A free, self-hosted Python library for extracting PDF text, layout, images, and fields.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
pdfminer.six is a community-maintained Python package for extracting information from PDF documents. It is aimed at developers who want to process PDFs from Python or a shell, rather than teams seeking a hosted extraction service. The library can return text or page-layout objects, and its documented capabilities include images, AcroForm fields, table of contents, and tagged content. It runs on Linux, Windows, and macOS and is distributed under the MIT license.
Its breadth is useful when extraction needs go beyond plain text. Developers can select pages or limit extraction by page count, inspect layout and text positioning, retrieve embedded images and interactive form fields, and decode encrypted PDFs with a password. Support for CJK languages and vertical writing also suits documents with those text formats. The package exposes a high-level Python API as well as a command-line interface, so it can fit code-driven and shell-based workflows. It is self-hosted, with documentation and community support channels.
The main boundary is scanned-document handling: OCR is not a capability, so image-only PDFs may need a separate OCR tool before text extraction is possible. There is no hosted service layer in the offering; implementation and processing belong in the developer's own workflow. The package is free and open source, so there are no paid tiers to compare. Choose pdfminer.six when you need programmable extraction from native PDF content and can manage processing yourself. Look elsewhere, or pair it with OCR software, if your core requirement is extracting text from scans or using a managed service.
