How to convert an ISO to ZIP online
- Drop the
.isofile onto the box above, or click to choose it. - The files in the image are packed into a ZIP on your device.
- Save the
.zipwhen it downloads, or use the file list to take out single files instead.
Why turn an ISO into a ZIP?
An ISO is a sector-by-sector copy of a CD, DVD or installer disc. To get at the files you normally have to mount it as a virtual drive, which is not possible on every system: Chromebooks, locked-down work laptops and phones often cannot. A ZIP of the same files opens anywhere and is easier to share, upload or archive.
Converting is also a quick way to keep only the contents of an old disc image, without the empty sectors and file-system padding that make ISOs large.
What is kept, and what is not
The folders and files on the disc are kept, with their names from the Joliet or UDF file system, so long and Unicode file names come out right. What a ZIP cannot hold is the disc itself: boot sectors and the disc layout are not carried over, so a ZIP made from a bootable installer ISO cannot be written back to a USB stick or disc to boot from. Keep the ISO for that.
Audio CDs and other images without a file system have nothing to convert. For .bin/.cue and .mdf images, use BIN to ISO first.
Large images stay on your device
The image is read from your disk in pieces, and the ZIP is written to the browser’s temporary storage, so a multi-gigabyte DVD image does not have to fit in memory or be uploaded. Most of the time is spent compressing; files that are already compressed, like video, are stored quickly.
Frequently asked questions
Is my ISO file uploaded?
No. The image is read and the ZIP is written inside your browser. Nothing is sent over the network.
Will the ZIP still be bootable?
No. A ZIP only holds files. Boot sectors and the disc structure of an installer image are not kept, so keep the original ISO if you need to boot from it.
Does it need to mount the ISO?
No. The image is parsed directly, so it works on systems that cannot mount disc images, including ChromeOS.
How large an ISO can it convert?
There is no fixed cap. Multi-gigabyte DVD and Blu-ray images work as long as the browser has enough free temporary storage for the ZIP, which is normally a share of your free disk space.
Can I convert a ZIP back to an ISO?
Yes, in two steps: extract the ZIP, then drop the folder on the ISO Creator. It makes a data image, not a bootable one.
