How to make an ISO from a folder
cdBurner can wrap an entire folder into a single ISO file — a tidy, portable snapshot you can keep or burn whenever you like.
Step by step
Connect the burn agent
Open onlinecdburner.com and connect the burn agent.
Add your files
Choose the files or folder you want in the image.
Choose “Save as ISO”
cdBurner builds a standard ISO 9660/UDF image — no disc required.
Download
Keep the ISO as a backup or burn it to a disc later.

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.
