Learning how to convert FLAC to MKV online for free has become increasingly straightforward with the assistance of the Online Video Converter provided by Movavi. FLAC, which stands for Free Lossless Audio Codec, and MKV, short for Matroska Video, are two distinct file formats, each tailored to fulfill specific functions.

FLAC is renowned for its outstanding audio quality, as it is a lossless audio codec that compresses audio files without compromising any audio data. It is particularly well-suited for individuals who are passionate about preserving the utmost audio fidelity. However, it's worth noting that FLAC files tend to be relatively large, which can pose challenges in terms of storage and sharing.

Conversely, MKV is a versatile video container format that is not limited to video alone; it can also accommodate audio, subtitles, and even chapter information. Although primarily employed for video content, MKV is fully capable of storing high-quality audio tracks, including those in FLAC format. Consequently, MKV is an excellent choice for organizing multimedia content with multiple audio and subtitle tracks, making it highly popular for various applications such as movies, TV shows, and video projects.

When the need arises to convert FLAC to MKV for free using the Online Video Converter, you essentially amalgamate the advantages of both formats. You retain FLAC's exceptional audio quality while wrapping it within the MKV container, which offers the flexibility to seamlessly combine audio and video components. This conversion process facilitates the creation of multimedia files that are more manageable and shareable, all the while maintaining the integrity of the audio quality.

In summary, FLAC and MKV are designed for different purposes, with FLAC emphasizing top-tier audio quality and MKV functioning as a versatile container for multimedia content. By utilizing the Online Video Converter to convert FLAC to MKV, you effectively bridge the divide between these two formats, ensuring that your multimedia content boasts superior audio quality while benefiting from the versatility of the MKV container.

What is FLAC?

Full name

Free Lossless Audio Codec

Format type

Audio

Developed by

Xiph.Org Foundation; Josh Coalson and Erik de Castro Lopo

Description

FLAC is short for Free Lossless Audio Codec. It was created in 2001 by the Xiph.Org Foundation but didn’t have a stable release until 2019. FLAC is useful when you want to compress audio without losing quality. But, like other high-quality formats, files with FLAC specifications can be huge. If your device doesn’t have much storage space, you might have problems maintaining a collection of FLAC files. Despite its popularity, media players like iTunes and QuickTime still don’t support audio playback of the FLAC format, and many mobile apps cannot decode it. You may want to consider converting your FLAC files to the more widely supported MP3 format to be on the safe side. Check the table below if you want to know how to open FLAC audio tracks and which programs can play them.

File extension

.flac

Technical details

Although FLAC files are compressed, they are of the same quality as the source audio. The audio files in lossy formats like MP3 or AAC have slightly worse sound quality than those of lossless formats. However, the difference may be almost undetectable if the lossy file has a high bitrate. Another feature of the FLAC file type is that it uses IDv1 and IDv3 tags. This allows the user to arrange their audio collection according to taste, changing the original track metadata.

What is MKV?

Full name

Matroska Multimedia Container

Format type

Video

Developed by

Lasse Kärkkäinen

Description

MKV (or Matroska Multimedia Container) is a free, open source video container format created in 2002. It’s officially called Matroska after the Russian matryoshka dolls because all the video, audio, and subtitle tracks are held within a single file. This format enables synchronous playback of audio and video tracks. Since MKV supports a large number of codecs and even uncompressed video, this format retains the original quality, allowing you to enjoy your videos in HD. Check this table if you want to know how to open MKV files and which programs can play them.

File extension

.mkv, .mk3d, .mka, .mks

Technical details

Videos with the MKV file type have a data channel for each type of track, making this format closer to other media containers such as AVI or MP4. A disadvantage of the MKV format is that very few modern programs can play files with these specifications correctly, so users have to install additional applications or codecs, for example, the VLC player or K-Lite Codec Pack.
