## What it is
PDF::Reader is a Ruby library that parses PDF files according to the Adobe PDF specification, providing programmatic access to document metadata, pages, text, fonts, and low-level objects. It is a low-level parsing foundation rather than a renderer, with convenient helpers for common tasks like text extraction.

## Use cases
- extract text from pdf files in ruby
- read pdf metadata and page count
- parse pdf objects programmatically
- iterate over pdf pages and fonts
- process pdfs from an io stream

## When to choose
- you need to programmatically inspect or extract text from PDFs in Ruby
- you want a low-level PDF parser to build higher-level tooling on
- you need UTF-8 text extraction from PDF pages

## When to avoid
- you need to render or display PDFs visually
- you need to create or write PDF files
- you work outside the Ruby ecosystem

## Facets
- artifact type: library
- maturity: active
- function: parser, pdf
- domain: pdf, files, parsers
- platform: ruby
