Handbrake may be the most welcomed free video converter for macOS. It is a cross-platform and free transcoder for Mac, Windows and Linux, able to rip and convert any type of video source. You can freely encode video on Mac to two formats: MP4 or MKV. Although not as extensive as other Mac video covnerting freeware provides, the two formats cater to your needs by and large. With support to Intel QSV in Hardware 1.0.0 or newer, the Mac video converter freeware is fast on Haswell or newer with HD Graphics on-board.

There are various confusing parameter settings. For example, there is a big difference in conversion speed between Very Fast and Fast profile or HQ and Super HD (Generally, HQ gives you a much greater speed than Super HQ in video conversion). For the layman, you'd better stick with the defaults. For advanced users, you can adjust those parameter settings, including video codec, frame rate, Bit rate, 2-pass encoding, audio sample rate, audio bit rate, video subtitles, etc.

However, there are often problems like MKV converting error, video audio sync trouble, etc. and there is no official support. Find answers from authoritative sites like Macworld, PCworld, which offer many Handbrake tutorials about video converting.

Why Need a Mac Video Converter

The demand for a video converter for Mac increases, especially when you reach out to platforms other than macOS. For example, you have some nice trip videos captured by your iPhone and want to share on SNS; you have a substantial library of movies and TV shows that span years of downloads and copies, but only to find them unwatchable on your Apple TV. What if you want to play 4K video on old Mac that isn't 4K capable? Downloading a free video converter for Mac is the solution to convert videos from one format to another.

play video on mobiles You want to play all videos on my device properly

MP4, MOV, and M4V are pro-Apple ecosystem while WMV and AVI are frequently used in Windows platforms. Formats of high-definition videos shot by camcorders include DV, AVCHD, MPEG-2, H.264, MTS and others. Chances are you want to import a 4K or 1080p recording into your iPhone or put a media file from your Windows 10 to MacOS. This makes it sensible to re-encode your video files.

compress large video You want to reduce the size of HD/4K videos

HD and 4K videos are regarded as the biggest space hogs. Typically, uncompressed 4k video is approx. 350mb/min compared to 120mb/min in 1080p. Even though Apple employed HEVC codec in iOS 11 or later, 4K videos still chew up iPhone storage space quickly, not to mention videos using H.264 codec. Compressing video to reduce the amount of data using HD/4K video procesing software will have your needs covered, whether you want to share over social networking sites, view over small iPhone iPad, or transfer through emails quickly. The process involves in changing to a format that takes up less space, lowering resolution, bitrate, frame rate, trimming the video file to shorten the length.

upload video online You want to upload videos online smoothly

Videos can be uploaded within allowed length, formats, codecs, aspect ratio and more. Anything incorrect will destroy the upload process. For example, it takes a long time to upload a 4k using HEVC codec to YouTube as it consumes too much source. There will be black bars during playback when you upload a video at a non-16:9 to YouTube. A video converter will address the issues by processing videos in a format that YouTube accepts, preferably MP4 H.264, cut unwanted parts and shorten the video within 15 minutes, downsize the video within 128GB, and change the aspect ratio to 16:9, if it isn't.

edit video You want to edit and archive my video downloads and records

You might have recorded some vacation videos shot your drone or camera. There migth be some daily shootings recorded by your phones, or some movies downloaded online. With the video converting tool for Mac, you can put these resources in a single format so that your Macbook Air/Pro will better archive them. Also turning these memorable moments into masterpiece is achievable with common video converting programs, as they are normally equipped with basic editing features that enable you to cut, trim, crop, merge and rotate video as per your needs. Follow the complete guide to edit videos on Mac >>

Does QuickTime Meet Your Video Converting Needs?

Users getting used to Mac platform may understand the QuickTime Player allows to convert videos in older or third-party media formats by taking advantages of Apple ProRes. It can export video to the specific destination format supported by iTunes and iMovie, optimize the media file for the web, or set more general format by selecting "Export". But if you'd like to go further with video conversion, for your Android device, for example, QuickTime is still far from perfect due to the limited codec, Windows-repellent video format list, and the no batch processing option. In addition, the QuickTime 7 is ditched from macOS Big Sur and Big Sur for the latest operating system only supports 64-bit apps. You have to choose the video converter software supporting the new OS.


Now you might have your own answer about which one you favor. In short, the overall performance of MacX gets the highest mark in our top video conversion freeware for Mac review.
