How to finalize a disc
An unfinalized disc often reads as blank elsewhere. cdBurner finalizes by default so your disc plays in other PCs, players and car stereos.
Step by step
Connect the burn agent
Open onlinecdburner.com. The first time, install the tiny one-time helper so the page can reach your drive — after that it just works.
Insert a blank disc and pick your drive
Put a blank disc in your writer and select it. cdBurner shows the disc type and free space.
Add your files (Finalize stays on)
Click Files or Folder and choose your files (Finalize stays on). A live gauge shows whether it fits.
Set options and burn
Pick a write speed, keep Finalize on for maximum compatibility, then click Burn disc.

Why cdBurner is different
Most burning apps are bloated installs full of upsells. cdBurner does the whole job from your browser — free, with no toolbars or trialware.
- 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.
