Top 10 Best 4K Video Converters for Windows (10)/Mac in 2021
4K wins its popularity for much crisper picture and higher definition it features. Its proliferation shows no signs of slowing down especially when GoPro, DJI, iPhone, Canon announce the ability to shoot 4k 10bit HDR video at up to 60fps. But is your PC really on deck to keep the ball of 4K videos rolling? There are times you need a 4K video converter to well handle 4K Ultra HD videos. Why?
Why You Need a 4K Video Converter?
- A 4k video is high in resolution, which is 4 times the pixel resolution of 1920x1080p.
- The bitrate is probably between 100-600mbps upon inter/intra compression, thus the file size is shockingly bulky - upon GBs.
- 4k frame rate reaches up to 60/120fps. This demands high on hardware compared with 4k 30fps or 1080p 60fps video.
- 4k video is commonly encoded with computer-intensive HEVC codec and 10bit color format, which requires weighty operation and thus exerts high requirement on PC, editing software, and more.
Consequently, it's hardly a seamless experience to play and edit 4K files on older computer. Choppy playback and high CPU usage frustrate you on your underpowered computer. Error messages such as "unsupported video codec", "codec missing" pop up when importing 4k footage. Playback gets suddenly laggy while editing 4k. Uploading them can be lengthy.

Top 10 Free 4K Video Converters for Windows and Mac
In the following section we share a handpicked list of top paid and free 4k video converters. Here is an at-a-glance look at our top picks. Let's hop into it straightaway.
#1. WinX Video Converter
WinX Video Converter is one of the top 4K video converters that give you an ultimate control over 4K, 5K, 8K, HD 1080p and large video files, no matter they're saved in .mov, .mp4, .mkv, or encoded in H.264, HEVC, VP9, AV1 video codec. It enables you to downscale 4k to 1080p or 720p for virtually all devices without jerky/choppy issues, and upscale 1080p to 4K UHD with best quality to perfectly fit with bigger 4K screen.
Bonus Points: These days, your smartphone, DLSR/mirrorless camera from Canon, Sony, GoPro or DJI can shoot high quality 4K video, but the size of the video file balloons quickly. It's painful when your memory card maxes out or you want to share one of the files on the internet. WinX Video Converter can compress and resize 4k without losing quality. It also features both an online 4K video downloader and a video editor to cut/merge/crop 4k file.
Unique Tech: WinX Video converter features the unique level-3 hardware acceleration tech, taking advantages of NVIDA CUDA/NVENC, AMD and Intel QSV to improve the efficiency of 4k video encoding, decoding and processing. Meanwhile, High Quality Engine and De-interlacing Engine go into high gear to assure a 4K ultra high quality at fast conversion. This helps to convert 4k video in a flash, and higher video size compression ratio is achieved with only subtle pixel-level quality difference!
Handbrake is an open source video transcoder that can free convert 4K (4096x2160 and 3840x2160) or 2K footage to popular formats like MP4 and MKV. It also works as a 4k upscaling software that includes 4k presets so that you can export 2160p content for 4k capable device like Roku, Apple TV 4k, Chromecast, etc. Learn more about how to use Handbrake >>
Bonus Points: The good thing we experienced with Handbrake is the support for batch processing in the queuing feature. This is especially helpful to encode a folder full of 4k x265 files freely in one fell swoop.
But: Handbrake is not very approachable look. Although it is packed with a handful of options available to customize precise encoding settings, tweak frame rate, and more, it means something of a learn curve to some extent, especially if you are just a beginner.
VLC is known as a free impressive media player to play 4K, 8K and other video/audio files without downloading additional codecs. It can also convert videos from one storage standard to another, including MP4, MKV, WMV, AVI, MOV, RAW and more.

Bonus Points: Supports 4K videos output from almost all cameras or camcorders, such as Canon, Nikon, Sony, Panasonic, JVC, Blackmagicdesign, etc; supports NVIDIA CUDA and ATI Stream acceleration technologies for streaming 4K videos fast.
But: It seems Acrok needs to change the visual appearance since the interface looks outdated. Plus, the custom options are limited, and the quality of output files is not so good as that of other 4k video converter tools.

FAQ about 4K Video Conversion
Q1. Can you convert a video to 4K?
Yes. Many programs do 4k upscaling. But there is no guarantee the upconverted footage gets better looking. At this point, the original video source, viewing distance and the screen play an important role if the quality matters a lot.
To be exact, pixels will be stretched bigger than they are made to be stretched, but the image quality is not truly 4k quality. If you watch the upconverted video on a large 4k screen, it will look pretty bad. This is especially true with your SD quality video such as 360p or 480p video. Only when the screen is small or the viewing distance is great, will there be less jarring between 4k and the upconverted video. So it's not advised to convert SD video to 4k, instead you can convert 720p or 1080p video to 4k with WinX Video Converter.
Q2. How do I convert 720p to 4K?
Converting 720p video to 4k means you can play it on a larger screen without pixelated problem. For the recent 4K TVs, they are equipped with upscaling tech that can upscale your lower-resolution content to fill the entire 4K TV screen. But if you want to upconvert 720p to 4K on PC, you need to rely on a 4k video converter software. WinX Video Converter is one such tool built in unique motion-adaptive 4k scaling algorithm, meant to fill new interpolated pixels into the source 720p video intelligently.
To do the job, just feel free to download the 4k video converter on your PC, load the source 720p video in whatever format, choose the output format 4K MP4 video, click RUN, and leave the program doing the rest.
Q3. Can converting affect 4K quality?
It depends. Any video compression will result in quality degradation, let alone 4k video transcoding. But if you just want to convert 4k video from one video format to another, without tweaking the video codec, bitrate, frame rate or so, there is no quality loss at all.
Q4. What's the best 4K video converter?
We've already listed the top video converters designed for 4K UHD video, with WinX Video Converter and Handbrake leading the pack. Generally, it will have a large range of format options, available to change video file into a different format or a compact file, either to play on a particular media player, or allow for a more efficient video editing process, fast sharing, and less consumption of space on your device. You can choose the one based on your specific needs. But there are key factors to be considered.
- Fast 4k converting speed: Speed is a key factor. Incapable tool will take a long time to convert 4K to 1080p video, and worse still crash when handling large 4k HEVC file. Resorting to a 4k video converter with hardware acceleration enabled is a cut-through way, as it utilizes GPU to decode, process and encode the massive data of 4k and spares CPU for other tasks, and thereby saving you a lot of time.
- Good 4k compression ratio: The good news is that almost all video converters can downsize 4k easily while the bad news is that you will lose video quality inevitably. So balancing the quality and file size is known as a crucial factor for 4k video converter.
- Customizable 4k video settings: Statistically, the current 1920x1080 display resolution accounts for 67%, which means playing 4k on the screen cannot be satisfied. Meanwhile, most video editors cannot handle variable frame rate and HEVC codec well and will result in A/V sync or codec error when processing 4k file. To the end, it will be the icing on the cake if the 4k video converter is available for you to tweak the video resolution, codec, frame rate and other parameters.
Q5. What is the minimum system requirement for 4k video?
To smoothly handle 4K video files, make sure that a qualified computer is in use. Here goes the minimum system requirements for 4K playback.
Minimum System Requirements
4K HEVC video Playback
7th generation Intel Core i7 (Kaby Lake) processor equivalent or better, 3.5GHz or better
Intel® Iris™ Pro Graphics 5200
8GB or more
1TB with at least 400M/S transmission speed for 4k video editing
Windows 10/macOS High Sierra or later
HDMI 2.0 or DisplayPort 1.2 for 4k 60fps
Make sure your 4k display is set to run at 3840x2160
HEVC video extension
At least 25 Mbps
If you are not planning to upgrade your computer system and handling the computer-intensive 4K video is a little bit troublesome, such as freezing and laggy playback, you can resort to a 4K video converter to transcode 4K video to a more compatible format for later playback smoothly.
Q6. What is 4k video?
4K resolution has already won a wide hardware and software support, which is on the way to insurgently overtaking other video resolutions like 1080p High Definition format.4K Ultra HD (4K UHD) video itself refers to the video of a pixel resolution of 4096x2160 (4,000 pixels, 8.8 megapixels, 17:9 aspect ratio) mainly for digital cinema, or of a resolution of 3840× 2160 (8.3 megapixels, 16:9 aspect ratio) mainly for Ultra HD television.
By far, HEVC/H265 codec and VP9 codec are driving the developement of 4K Ultra-high definition videos. 4K is four times of the resolution of 2K projector and 1080p HDTV. At 4K resolution, every single details and Close-ups on the image can be seen. If adopting the amazing 4096x2160 UHD resolution in cinema, a film can deliver an indescribable and unprecedented enjoyment for audiences at any angle for the crystal clear picture, sparkly bright color and Hyper-reality sound (if any).
