DVD Copy
Updated 2026-06-22 // Personal-archive referenceCopying a DVD keeps the disc exactly as it is — same menus, same audio tracks, same chapters — rather than converting it to a single video file. People copy discs they own to guard against scratches and wear, to keep a master before lending the original, or to store the whole collection as disc images on a drive. This page explains the kinds of copy you can make, when to compress, and how the process works.
This page covers copying discs you own, for your own backup — home recordings and commercial discs where personal backup is permitted. Laws on copying encrypted commercial discs vary by country, and circumventing copy protection to share or distribute content is out of scope here. Check the rules where you live before copying a protected disc.
Three ways to copy
| Method | What you get | Best for |
|---|---|---|
| Disc → disc (1:1 clone) | A spare disc that plays in any player, menus and all. | A ready-to-play backup of the original. |
| Disc → ISO image | One .iso master file on your computer. | Archiving — re-burn or mount as a virtual disc later. |
| Compressed copy | A dual-layer disc squeezed onto a single-layer blank. | Fitting 8.5 GB onto 4.7 GB media, or main-title-only. |
When to compress, when not to
If your blank disc is the same capacity as the original, copy without compression for a true 1:1 result. You only need compression when squeezing a dual-layer disc onto a single-layer blank. In that case, copying the main title only — dropping trailers, extras and unused language tracks — keeps the film at higher quality than compressing the entire disc. Modern copy tools show a capacity meter so you can see exactly what will fit.
Copying to an ISO, step by step
- Insert the DVD and choose "copy to ISO image" (sometimes called "save as image" or "rip to ISO").
- Pick a destination folder with enough free space — up to about 8.5 GB for a dual-layer disc.
- Start the read. The tool produces a single
.isofile that mirrors the disc. - To use it later, either burn the ISO back to a blank disc or mount it as a virtual drive to play it without the physical disc.
Cloning to a blank disc, step by step
- Read the source disc to a temporary image on your drive.
- When prompted, swap the original for a blank disc of the right type and capacity.
- Burn at a moderate speed for reliability, then finalise.
- Test the copy in a player before you put the original away.
DVD copy on Mac
macOS handles disc-to-ISO natively in some workflows, but a dedicated copy tool gives you the capacity meter, main-title selection and reliable burning that backups need. As with ripping and authoring, most Macs require an external USB DVD drive, and on Apple Silicon you should pick software built for current macOS. Reading to ISO and burning back behave the same as on Windows.
Storing your copies
ISO images are the tidiest way to archive a collection: one file per disc, easy to back up to an external drive or NAS, and burnable again at any time. Label them clearly and keep a second copy of anything important — a single drive is not a backup. Burned discs should be stored upright, out of direct sunlight, to last.
Frequently asked questions
What's the difference between copying and ripping?
A copy keeps the whole disc structure — menus, tracks and chapters. A rip converts the video into a single file such as MP4 or MKV.
Can I copy a dual-layer disc onto a normal blank?
Yes, with compression, or by copying the main title only. Both let an 8.5 GB disc fit on a 4.7 GB blank; main-title-only usually looks better.
How do I play an ISO without burning it?
Mount the ISO as a virtual drive — most operating systems and media players can open it directly, so it plays just like the disc.
