How To Convert ZIP To ISO

I wanted to download some iso files online but ended up downloading the zip format. However, I needed to save myself the stress and data of downloading the intended version of these files. Could you please help out on how to convert zip to iso? Thanks!

There are cases where the need for file compression is of necessity. The process of file compression allows the sizes of large files to be significantly reduced or shrunk such that they can be seamlessly transmitted over the internet. Downloading such files from the internet can be quite easier and also allows additional data to be stored on removable media, e.g USB flash drives, memory cards, optical discs, etc.

Although there are many types of compression formats, zip file format is one of the most commonly used ones. Windows users can easily zip and unzip their files without the need for additional programs. However, the conversion of a zip file to iso image usually requires the implementation of multiple programs because a direct method of conversion is yet to be devised.

You are quite fortunate these programs are available and they will make your work much easier. You shall be educated about what ZIP and ISO files are and how to go about their interconversion. Read on!


What ISO files are… An ISO file is otherwise known as a disc image (archive file) and it is the exact copy of the content of an optical disc (e.g CD or DVD) which carries the extension “.iso.” Not only does it contain files and folders, but also the exact configuration of the duplicated disc. Moreover, ISO files are useful in creating backups for discs or distribution of software programs, hence, they can be used in place of the original disc.

On the other hand, a compressed archive file such as ZIP could be different from what has been described above since an archive file is expected to contain only the files with the exemption of every other unused data. You could easily conclude that files such as ISO are uncompressed archives. Could this be true?

Well, that can’t be totally correct! Even with uncompressed archived files, unused data would still be removed. Imagine zipping up say a 35GB file and you still end up getting the same file size — This only implies that the 35GB file obtained is the actual data that fills up the original file, therefore, compressing such file wouldn’t be necessary. However, if there was only 10GB of useful data on that disc and it is archived without any compression, you would get a 10GB file.

Recall that ISO files are the exact copy of a disc and the conversion is done irrespective of the unused data, the resulting file would always be of the same size as the original. Thus, if you convert a 35GB file to an ISO image, you would still get a 35GB ISO file at the end of the conversion process.

How useful creating the disc image of other file formats cannot be overemphasized. The main objective of such conversion is to duplicate the original file by burning it into as many discs as possible, thereby, making different copies available. It is very important to know that the arrangement in the original file is not in any way jeopardized and one can be sure to have the same configuration when an ISO file is burnt into another disc.

What More Can Be Done With Zip Files?

Let’s think of zip files as the usual folders on our PC. Often times, you want to create a folder and move as many related files into it to keep them organized. Once a folder is created, you can easily transport it alongside its contents to any location on your PC without having to move the files individually. However, the size of this folder is cumulative of the sizes of an individual file. Although zip files work in the same manner, their contents are usually compressed to lower storage use, moreover, such files have to be unzipped to extract their contents. The zipped version of a file ends with the “.zip” extension and you could easily identify one when seen.

Assuming you are to email several files to a coworker or any other associate, would you have sent the folder containing these files? It is quite unfortunate that won’t be possible, instead, you would have to send individual files and that might not be easy especially if they were to be large files. Yeah, this is where zip files come into play!

With the appropriate tool, you can easily zip your files into a single file or folder with their sizes being significantly reduced for easy transmission. The quality of the original file may be retained. Moreover, this archiving system enables you to encrypt and add a password to your files so they can be protected from unauthorized access.

Step-By-Step Process To Convert ZIP To ISO…

There are many ways to maneuver around the conversion between the two file formats, however, we shall put you through the process we deem simpler. Before proceeding to that, you might be interested in how to zip and unzip files. If you already know how you may skip this and move to the conversion of ZIP to ISO.

It requires you to first unzip the files, then, convert them to ISO using a program called UlraISO…

Unzip the Zip File First

Step 1: To decompress your Zip file on windows, you are going to make use of WinRAR. Right-click on the file, navigate to and select “open with > WinRAR.” Clicking on this option automatically launches the zip file in WinRAR along with its contents.


Step 2: You should see the “Extract to” option at the top of the program’s interface. Click on it and wait for a new window which carries the title “Extraction Path and Options” to pop up.

Step 3: On the new window in the previous step, select your preferred extraction path, that is, where you would like to save the unzipped files. You can do this either by inputting a phrase in the search box at the top or just clicking the directory, then, click “OK” for the zipped file to be extracted.


Convert to ISO Using UltraISO

Step 1: Launch the UltraISO program via the start menu or any other means that is easy for you. Click on start; navigate to program files; search and launch UltraISO.

Step 3: Now, locate the unzipped or already extracted files by navigating through the file browser near the bottom of the program interface.


Step 4: After you have been able to locate the files in the previous step, select and drag them to the “new ISO file” you created in step 2 — Now at the upper pane of the software interface. Once you’re done with that, you should save this by clicking on “File” then “Save.” You may give this new file a distinct name for easy identification.

Alternative Solutions

Apart from the method described above, you may also go about the process using the step-by-step processes explained below.

Step 2: Now, locate the unzipped or already extracted files by navigating through the file browser of the program interface.


Step 3: The extracted files, once located, should be selected and dragged into the empty pane of the software at the top where they would be listed.

Step 4: Save this by clicking on “File” then “Save.” You may give this new file a distinct name for easy identification.



In this article, it was made clear that there is no any zip to iso converter program that could help users with direct conersion of zip files to ISO images, however, the above processes are quite simple to execute once the right tool is available on your PC. You should know that you can use either of the two unzipping tools, and either of the two ISO tools — there is no issue with compatibilities and it is not necessary to use them as they have been paired, but follow the processes described under each.

Also, it is not necessary to have your files in “.zip” format before you can apply the ISO tools. That is, you can convert your files to the “.iso” format provided they are not compressed.
