A curated community driven list of awesome PDF (Portable Document Format) libraries, services and datasets. Both open source and commercial services are included and accepted.
When working with PDF files, you sometimes come across great services, libraries, or interesting tools that you want to remember. Here is our list. From parsers for extracting text, images, and tables, to automated PDF creation and processing, to accessibility and compliance. AI included!
- Parsers, OCR and extraction - If you need to extract something from PDFs look here.
- Creation and production - Need to produce PDF, here some of the cool libraries and services
- Readers and viewers - Need to show PDF in your app or site, maybe here you can find something.
- Accessibility - Accessibility and long term conservation is a hot topic, give it a look!
- Datasets - Entering the machine learning and artificial intelligence dimension. Maybe here you can find a dataset to train your new shiny model!
A community-driven list is, at its core, driven by contributions. If you stumble upon a great service or library, or find mistakes, please get involved by starting a discussion or suggesting a change via a pull request.
