  "IronPdf": 
    "LicenseKey": "YOUR-KEY-HERE"

Q2: Do I need a license key for a Docker container?

A: Yes. In a Docker environment, set the IRONPDF_LICENSE environment variable in your Dockerfile or docker-compose.yml. Do not bake the key directly into the image file.

IronPDF utilizes a tiered licensing structure designed to accommodate different scales of use, ranging from individual developers to global enterprises. The basic tiers usually cover a single developer for use in one project, while higher tiers allow for multiple developers, unlimited projects, and redistribution rights. This redistribution aspect is particularly important for software companies that sell their own products with IronPDF embedded as a feature. The license key serves as the digital proof of purchase that aligns the software's functionality with the specific legal permissions granted by the chosen tier.
