Best ISO Converter for DVD ISO Backup, Conversion, Creation, and Extraction

Updated on Sep 3, 2026

An ISO file can mean different things. In this guide, the main focus is a DVD ISO image—a disc image that preserves the DVD structure in one file. You may want to create one as a backup, or convert an existing DVD ISO to a regular video or audio file for easier playback, editing, storage, and sharing. Below, you will find practical tools for these different ISO tasks, starting with WonderFox DVD Ripper Pro for DVD and DVD ISO conversion.

An ISO image is a sector-by-sector or file-system image of an optical disc. A DVD ISO can preserve the disc structure for backup or later burning, while a converted video file is usually smaller and much easier to play on phones, tablets, TVs, media servers, and editing software. These are different goals: creating an ISO keeps the disc-like structure, while converting a DVD ISO to video/audio extracts and encodes the movie content.

This guide shows how to convert DVD-Video to ISO or ISO to other digital formats. It mainly focuses on DVD sources, including physical DVD discs, DVD ISO images, and VIDEO_TS folders. It is not a general-purpose converter for operating-system ISOs, software installation ISOs, game-disc images, or arbitrary data ISOs. For those files, use mounting, extraction, or ISO-authoring tools instead.

WonderFox DVD Ripper Pro – A Recommended Converter for DVD ISO Images

WonderFox DVD Ripper Pro handles three common DVD sources: physical DVD discs, DVD ISO images, and DVD folders. You can make a 1:1 ISO or DVD-folder backup from a disc, or rip a DVD ISO to one of 300+ configured video, audio, and device profiles. It can also analyze many protected DVD sources, automatically identify the main title, and let you keep the audio track and subtitle combination you need.

For digital conversion, you do not need to focus on a single output format. Choose based on where the file will be used—for example, a broadly compatible video container for everyday playback, a device preset for a phone or TV, or an audio profile when you only need the soundtrack. You can also adjust resolution, bitrate, frame rate, and deinterlacing when necessary. The software is available for Windows:

Part 1: Convert DVD to ISO with WonderFox DVD Ripper Pro

Add a DVD movie into the disc image file converter

Before start, please free download free download the software and install it on your Windows PC.

Step 1. Load the DVD disc you want to convert DVD to ISO

Insert your DVD disc into DVD driver. Then run WonderFox DVD Ripper Pro and click on “DVD Disc” to select the target DVD source.

Step 2. Choose output format as ISO

After the DVD loading process is finished, click on Output Format on the right, and select ISO under the 1:1 Quick Copy section.

Tips: ISO output is intended to preserve the DVD structure as a disc image. If your goal is simply to watch the movie on another device, skip this backup profile and use Part 2 to create a regular video file instead.

Step 3. Start converting DVD to ISO with the ISO file converter

Click on the Run button to start creating the ISO image. The actual time depends on the disc size, condition, drive speed, and computer performance, so a full DVD backup may take several minutes or longer.

Part 2: Convert a DVD ISO Image to a Playable Video or Audio File

Download Download the DVD ISO converter and install it on your Windows PC. These steps apply to DVD ISO images rather than general data or operating-system ISO files.

Step 1. Add ISO Image to the Program

Click the ISO Image button and select the DVD ISO image from your PC. The program will scan the DVD structure and normally select the main movie title automatically. For a TV-series ISO file with with several episodes, it will select all the content you actually want to convert.

Step 2. Choose the desired output format

Press the output format button on the right and choose a profile based on your purpose. The profile library includes 300+ configured options, including common containers and codecs such as MP4, MKV, MOV, AVI, WMV, VOB, H.264, and H.265.

Note: Selecting VOB creates a standalone .vob video file from the selected DVD title. This is different from simply mounting or extracting the ISO that can expose the original VIDEO_TS folder with all existing VOB/IFO/BUP files.

Step 3. Finish the conversion at once

Choose an output folder and click Run to start the conversion. Hardware acceleration can speed up supported encoding tasks on compatible Intel or NVIDIA hardware.

After the process finishes, play a portion of the output to confirm that the picture, audio track, and subtitles are correct before deleting or moving the original ISO.

Tip: Before starting, you can select the preferred audio track and subtitles. Open Settings only when you need to change items such as resolution, bitrate, frame rate, or deinterlacing. Higher bitrate can preserve more detail but creates a larger file, while aggressive compression saves space at the cost of quality.

Other ISO Tasks: Create an ISO or Extract Its Contents

Not every ISO task is a video-conversion task. If you need to package ordinary files and folders into an ISO image, use an ISO-authoring tool. If you only need to access the files inside an ISO, you can mount or extract it instead. These methods are suitable for general data ISOs as well as many disc-image files.

How to Create an ISO File from Files or Folders with ImgBurn

Convert from folder to ISO

Preparation: Install ImgBurn on your computer: https://www.imgburn.com/index.php?act=download

Step 1. Open ImgBurn and select Create image file from files/folders.

Step 2. Add the files or folders you want to include in the Source area.

Step 3. Choose a destination and file name for the ISO image.

Step 4. Review the file-system and label options if your project requires specific settings.

Step 5. Click the Build button to create the ISO file.

Note: This creates a data/disc image from the selected files. Simply putting random video files into an ISO does not automatically create a standard DVD-Video disc structure that a DVD player can recognize.

How to Open or Extract an ISO to a Folder on Windows

Extract ISO file

On Windows 10 and Windows 11, you usually do not need an extra program just to access a standard ISO image.

Step 1. Right-click the ISO file and choose Mount. You can also double-click it when ISO files are associated with File Explorer.

Step 2. Open the new virtual DVD drive that appears in File Explorer.

Step 3. Copy the files and folders you need to a normal folder on your hard drive.

Step 4. When finished, right-click the virtual drive and choose Eject.

If you prefer direct extraction, archive tools such as WinRAR can also open and unpack ISO files. For more options, see: 3 Simple Methods to Extract ISO File >>

Frequently Asked Questions

Q1. Can WonderFox DVD Ripper Pro convert every type of ISO file?

No. It is designed for DVD sources, including DVD ISO images. General data ISOs, operating-system installers, game images, and software installation ISOs should be mounted, extracted, or handled with a dedicated disc-image tool instead.

Q2. Is converting a DVD ISO the same as extracting it?

No. Extraction copies the files stored inside the ISO, while conversion reads the DVD video content and creates a new playable video or audio file. Choose extraction when you need the original files, and conversion when you need easier playback or a smaller digital copy.

Q3. Which output format should I choose for a DVD ISO?

Choose according to the target device or software rather than the ISO itself. A common video profile works well for everyday playback, while an editor or older device may require a different container or codec. When unsure, check the supported formats of the device or app you plan to use.

Q4. Can I get VOB files from a DVD ISO without converting?

Often, yes. A standard DVD-Video ISO normally contains a VIDEO_TS folder with VOB, IFO, and BUP files. You can mount the ISO in Windows and copy those files out if you want the original DVD structure. Use the VOB output profile in DVD Ripper Pro when you want to process a selected DVD title into a standalone VOB file instead.

Q5. Will converting a DVD ISO reduce quality?

Re-encoding to a compressed video format can introduce some quality loss. Using sensible resolution and bitrate settings helps keep it minimal. If you need to preserve the DVD structure rather than create a smaller playable file, make a 1:1 ISO or DVD-folder backup instead.

Wrap-Up

The right ISO tool depends on what you are trying to do. Use WonderFox DVD Ripper Pro when the source is a DVD disc, DVD ISO image, or VIDEO_TS folder and you want a backup or a playable digital copy. Use ImgBurn when you need to build a general ISO image from files and folders, and use Windows mounting or an archive utility when you only need to access the contents of an ISO. Keeping these jobs separate avoids unnecessary conversion and helps preserve the data you actually need.
