## What it is
Snappy is a PHP library that wraps the wkhtmltopdf and wkhtmltoimage binaries to generate PDFs, snapshots, or thumbnails from URLs or HTML pages. It provides a simple object-oriented API and has framework integrations for Symfony, Laravel, and Zend Framework.

## Use cases
- generate a pdf from a url in php
- convert html page to pdf
- create thumbnails or screenshots of web pages
- merge multiple urls into a single pdf
- render invoices as pdf from html templates
- snapshot a webpage as an image

## When to choose
- you need server-side PDF or image generation from HTML in a PHP application
- you can install and control the wkhtmltopdf binary on your server
- you want a thin, well-maintained wrapper with framework bundles available

## When to avoid
- you process untrusted HTML or JavaScript, since wkhtmltopdf's local file access can be a security risk
- you need modern CSS support or a pure-PHP solution without external binaries
- you are not using PHP or cannot install system binaries

## Facets
- artifact type: library
- maturity: stable

- domain: pdf, web-development, files
