Note: You can convert Netflix downloads to MKV, but only with restrictions. Netflix’s DRM system prevents direct file conversion, so you must rely on third-party methods. Options include direct downloading through Netflix video converters like KeepStreams, re-encoding MP4 files into MKV, or screen recording.
Watching Netflix videos offline is fantastic, but Netflix's download device limit does not allow me to watch them on other devices, and I have to pay a more expensive subscription plan to enjoy this download feature.
So, I want to download Netflix videos without DRM and device limits in case of there are times when internet connectivity may not be available.
This post will go over how to download or convert Netflix videos to MKV format. Each method differs in quality, subtitle retention, and legality. Personally, I believe it is important to remind readers: these methods should only be used for personal, lawful viewing, and Netflix remains the official authority.
What is MKV and How Does It Differ from MP4?
Note: MKV is better for preserving every detail, while MP4 is better for quick compatibility. That’s why many people look for a Netflix video converter that offers both formats.
When I first encountered MKV, I was drawn to its flexibility. Unlike MP4, MKV doesn't limit the number of audio tracks or subtitle streams that can be in a single file. Instead of playing each video, audio, or subtitle file separately, it saves them all.
This makes it very appealing to movie fans who like to switch between languages or watch with director's comments.
I often tell my readers that MP4 is like a small suitcase: it's light and works with almost all devices. MKV, on the other hand, is like a bigger trunk: it can hold more and provide you more options, but it doesn't necessarily work with other things.
This difference helps explain why some users want to know if they can change Netflix downloads to MKV.
Definition of MKV
MKV stands for Matroska Video, which is a free container file that is open to everyone. It lets you add as many audio, video, and caption tracks as you want. A lot of people like MKV because it keeps material in its best form, with multiple soundtracks and advanced subtitles like ASS or PGS. Personally, I think MKV is the best way to store foreign films with different language tracks.
MKV vs MP4: Key Differences
Both MKV and MP4 are files, but they work in different ways when you use them. MP4 works on almost all devices, making it great for phones, computers, and TVs. But MKV is great when you need to have fine-grained control over playback, like keeping Dolby Atmos audio or moving between subtitles.
| Feature | MKV | MP4 |
|---|---|---|
| Audio/Subtitle | Multiple tracks, advanced subtitle formats | Limited subtitle support |
| Compatibility | Best on PC players (VLC, PotPlayer, Plex) | Universally supported |
| File Size | Larger, depending on content | Typically smaller |
| Use Case | Archiving, preserving multiple streams | Portable playback |
Methods to Convert Netflix to MKV
Note: There is no universal “best” method—only the best method for your needs. If you want maximum quality, go for direct MKV downloads.
I know from years of editing that most readers don’t just want theory—they want practical steps. There are three main approaches, each with unique strengths and weaknesses. I’ll walk through them as clearly as possible so you can choose the method that matches your needs.
Method 1 – Direct Download Netflix Videos in MKV Format with KeepStreams
The first choice is to use software made just for Netflix, like KeepStreams for Netflix. KeepStreams is helpful for me because it keeps files as close to the source as possible without having to re-encode them.
Still, direct downloading comes with limitations. It depends on Netflix’s regional settings, requires subscription access, and must constantly adapt to updates in Netflix’s DRM system. If Netflix changes its encryption, you may need to update the software before continuing to download. This software is capable of downloading Netflix videos efficiently in just a few straightforward steps.
Step 1: Launch KeepStreams and Choose Settings
The default download output format of KeepStreams is MP4, so first you need to click the Settings icon in the upper right corner, then select the Settings text, select MKV in Video Format, and click "OK".
Step 2: Log into Your Netflix Account and Play Desired Content
The primary interface will display icons for numerous streaming services. To select this service, click on the Netflix emblem.
To get to your Netflix account, you will need to enter your login information on a login screen. Find the movie or TV show you want to download and press "Play."
Step 3: Download Netflix Videos as MKV
KeepStreams will show you the download window. You can also choose quality settings (e.g., HD, SD) here. Click the download button, and KeepStreams Netflix Downloader will begin downloading your chosen content immediately.
Upon completion of the download, the file will be saved to the designated folder on your computer. KeepStreams Netflix Downloader enables you to effortlessly download your preferred Netflix episodes and movies in high-quality MKV format.
Method 2: Download MP4 Netflix Videos and Convert them to MKV Format
You shouldn't worry if you can't get Netflix movies directly in the MKV format. There are two steps that will help you keep watching your favorite shows. First, use KeepStreams to download the movie in MP4 format. Then, use a reliable tool to convert it to MKV format.
After that, you need a video converter like Movavi to turn MP4 videos to MKV, AVI, and other formats. The Movavi video converter makes it easier to download Netflix movies and change their format to any other format you want.
Step 1: Put the Movavi Video Converter program on your computer and run it.
Step 2: Select the "Options" icon situated in the lower left corner to modify the output format to MKV. Click "OK" to verify.
Step 3: The MP4 Netflix video that was recently acquired can now be transferred to Movavi by dragging it. Click on the "Convert" button to initiate the conversion procedure.
Your computer will have the same video stored in both MP4 and MKV formats upon completion of the conversion.
I often recommend this route to tech-savvy readers who don’t mind a little extra work. However, every re-encoding introduces some quality loss. Files may also take longer to process, and preserving advanced subtitles can be tricky.
Method 3 – Screen Recording to MKV
The third choice is the most common: recording your screen while watching Netflix movies. You just use recording software that saves in MKV file to record Netflix playback. I've tried this myself, and it does work, but you have to watch the whole video at once.
This method sacrifices quality and may lose Dolby Vision or Atmos audio. It’s also the slowest option, but it works even when downloads aren’t available. In my opinion, screen recording is best treated as a backup rather than a main solution.
Comparison of Conversion Methods
I always encourage readers to make informed decisions. I made a simple grid to show how each way stacks up against the others. We're not going to tell you which is better; we're just going to help you pick the one that works best for you.
| Factor | KeepStreams Direct MKV | MP4 → MKV | Screen Recording |
|---|---|---|---|
| Video Quality | Lossless 1080p/4K | Some loss | Lower |
| Audio/Subtitles | Fully preserved | Partial | Limited |
| Speed | Fast | Moderate | Real-time only |
| Stability | High | Depends on tool | Varies |
| Legality | Personal only | Personal only | Personal only |
| Best For | Archiving | Tech hobbyists | Occasional save |
Legality and Compliance Risks
Note: : You can convert Netflix to MKV, but always remember that Netflix’s policies are strict. Any conversion is only defensible when done for private use.
I believe this is the most important section. Many readers assume that because conversion is technically possible, it must be legally safe. That is not true.
Official Netflix Rules (2025)
- Plan with ads: 15 downloads per month per device, up to 2 devices.
- Standard/Premium plans: device count varies (1–4).
- Some titles include a yearly download limit.
- Downloads typically expire after 7–30 days, or 48 hours after playback begins.
- Not all titles are available for offline download.
I’ve often told readers: “Technical ability does not equal legal permission.” Converting Netflix to MKV is best limited to private, non-commercial scenarios.
Troubleshooting Common Issues
Note: Most issues—expired files, missing subtitles, device limits—are explained in Netflix’s own support pages. Knowing the rules helps avoid frustration.
Even when methods work, problems often arise. Over the years, I’ve heard from countless readers frustrated by errors, and most of them fall into a few familiar categories.
One common issue is expired downloads. Netflix automatically sets expiration dates, so you may see a clock icon or a warning message. The fix is usually simple: renew the download if the title is still available. Another issue is hitting the yearly download limit—in this case, there’s no workaround; you must stream online.
Missing subtitles are another frequent complaint. If you converted via MP4 first, it’s possible that subtitles didn’t carry over. In those cases, I suggest either re-downloading in MKV mode or manually adding subtitle files.
FAQs

A1. Netflix downloads come as .NFV files that are encrypted with DRM and can only be played in the Netflix app.
Q2. Why do my downloads expire so quickly?
A2. Netflix sets expiration at 7–30 days, or 48 hours after playback begins. This ensures content licensing is respected. However, KeepStreams can keep your downloads forever.
Q3. Is there a free online Netflix to MKV converter?
A3. Not legally. Free sites often contain malware. Stick to trusted, paid tools.
Q4. Does converting Netflix to MKV affect video quality?

Final Verdict
Regardless of your location or internet connection, downloading Netflix movies in MKV format is a terrific method to watch your favorite films and TV episodes offline. You can also check Amazon Prime Video download to MKV.
I’ve spent years writing about streaming, and I know how frustrating it can be when you just want to keep a film in the format you prefer. Personally, I find MKV invaluable for archiving, but I never forget the legal boundaries.
