How to burn a CD-RW disc
A CD-RW holds 700 MB — erasable and reusable, though some older players refuse rewritable discs. Here's how to burn one from your browser with cdBurner, using the drive in your own PC.
Quick facts
- Capacity: 700 MB
- Type: CD-RW
- Erasable and reusable, though some older players refuse rewritable discs.
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
Click Files or Folder and choose your files. 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.
