DVD-R vs DVD+R: which to choose?
DVD-R and DVD+R both hold 4.7 GB and work in almost all modern drives. DVD-R is marginally more compatible with very old players; DVD+R has slightly better error handling. For most people they're interchangeable.
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.

Why cdBurner is different
Every other burner is a program you install. cdBurner isn't: it runs in your browser with one tiny background helper, and it's free.
- 100% free — no trial, no watermark, no nag screens.
- Private — files are written locally and never uploaded to a server.
- No bloatware — one small signed helper, not a heavy install.
- Built on Windows' native IMAPI2 engine, so your discs read everywhere.
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.
