Burn button greyed out - how to fix it
A greyed-out burn button usually means no writable disc is detected, no files are added yet, or the burn agent isn't connected. cdBurner enables Burn once a blank disc, your files and the agent are all in place - this guide walks through each check.
Knowing this helps you pick the right disc and settings the first time, so your burns read everywhere and last. When you're ready, cdBurner applies sensible defaults automatically.
Quick facts

Frequently asked questions
Do I need to install software to burn discs?
Not a heavy program. cdBurner runs in your browser and only adds a tiny one-time burn agent so the page can reach your drive.
Which disc should I use?
It depends on size: a CD for audio and small jobs, a DVD for video and backups, a Blu-ray for large archives. See CD vs DVD vs Blu-ray.
Is cdBurner really free?
Yes — completely free and ad-supported. No trial, no watermark and no paid tier.
