Convert ISO to MP4 in 2025: The "One-Step" vs. "Two-Step" Workflow
GeorgeNov 19, 2025Table of Contents
ISO files are excellent for backups, but they are difficult to use. You can't play them on your phone, tablet, or TV, and they take up massive amounts of hard drive space.
📌The goal is simple: Get a high-quality MP4 file.
However, achieving this is surprisingly complicated. Most users download a free converter only to encounter error messages or unplayable files. This usually happens because of one hidden barrier: Encryption (DRM).
Solution A: Convert ISO to MP4 Using Free Tools
Best for: Users with zero budget who don't mind installing multiple programs and managing large temporary files.
1. How to Convert ISO to MP4 with HandBrake
HandBrake is an open-source transcoder that supports ISO to MP4 conversion. It allows video transcoding and ISO ripping on Mac, Windows, and various cross-platform devices. Supporting MP4, MKV, and WebM formats, HandBrake comes with a series of useful features such as dynamic range compression, embedded subtitles, frame rate control and more. Meanwhile, it's confusing for newbies.
- Supports conversion of videos, DVDs, and Blu-ray discs seamlessly
- Easily convert ISO to MP4 on Mac, Windows, and various platforms
- Pre-configured presets simplify the conversion process for faster results
- Advanced tools allow fine-tuning of encoding settings, frame rates, and codecs
- Batch conversion enables the simultaneous processing of multiple ISO files efficiently
- Occasionally, errors may occur during the conversion process
- Editing features and output formats are somewhat restricted and limited
- HandBrake cannot bypass DVD copy protection for encrypted ISO files
Launch HandBrake on your device.
To begin, add your ISO source file and allow it to scan.
For Windows users, select File to import a single ISO or choose Folder to upload a directory containing multiple ISO files for batch processing.
On Mac, HandBrake will prompt you with a dialog box to select your source file. Navigate through your Mac's directories to locate and import the desired ISO file.
Allow HandBrake to complete the scanning process before proceeding.
Configure Output Settings
Locate the Summary tab and pick MP4 as your output file format. In the other available tabs, you can adjust various settings, such as video quality, frames per second (FPS), audio codec, and subtitle options, to suit your preferences.
Set the destination and start the conversion
Hit the Browse button to specify the name for your output MP4 file and select the targeted location on your device.
On Windows, click "Start Encode". For Mac, simply select "Start" to begin the conversion process.
2. How to Convert ISO to MP4 with "MakeMKV + HandBrake" (Copy-Protected DVDs)
HandBrake is only a transcoder: it can convert video formats, but it cannot remove DVD copy protection by itself.
Because of this, there are two typical workflows:
- using HandBrake alone for non-encrypted ISO files, and
- using MakeMKV + HandBrake as a two-step process for copy-protected DVDs.
Major Features
- Completely Free
- Can decrypt copy-protected DVDs
- Users can save .mkv files for collection; .mp4 for storage and playback
Limitations
- You need to download, learn, and operate at least two (or three) different programs.
- If your ultimate goal is MP4, this "MakeMKV + HandBrake" two-step process
- The DRM handling is also limited.
Open MakeMKV and load the DVD ISO file as the source.
After scanning, select the main title and the audio/subtitle tracks you want to keep; Choose an output folder and click "Make MKV" to create a decrypted MKV file.
Use HandBrake to convert MKV to MP4
Launch HandBrake and import the MKV file created by MakeMKV; In the Summary tab, select MP4 as the output format.
Adjust encoding settings (codec, bitrate, resolution, audio, subtitles) as required; Set the destination path and file name, then click Start Encode (Windows) or Start (macOS) to convert MKV to MP4.
Feedback on Free ISO to MP4 Converters and "Two-Step Workflow"
Since HandBrake cannot handle encryption by itself, a common community workflow is to split the job between two tools: one for decryption and extraction, and one for compression and format conversion.
The two-step method is free, flexible, and capable of very high quality, especially if you keep the MKV as a lossless archive and produce a smaller MP4 for daily viewing. In return, it is usually more time-consuming and storage-intensive than an all-in-one solution, and it requires managing multiple tools and file paths. For users who value cost savings and control, however, this modular approach remains a practical and widely used option.
Solution B: Convert ISO to MP4 with All-In-One Software
📌Best for: Users who want high-quality results without the technical hassle.

Feedback on "One-Step" ISO to MP4 Converter
The one-step approach offers a streamlined workflow: it reduces setup, limits intermediate files, and combines decryption and conversion in a single interface, which can be helpful for users who value convenience and time savings. The main trade-offs are that it is paid software and only runs on supported platforms.
