How to convert MKV to FLV?
You can convert MKV to FLV with MConverter in three easy steps:
Choose MKV files from your device or cloud storage
At the top of this page, drag and drop your MKVs.
Alternatively, click on the Browse box to select files with your device's file picker, or copy and paste an MKV file by pressing Ctrl+V (or ⌘+V on Mac).
MConverter can easily import MKVs from Google Drive, OneDrive, and Dropbox.
Converting a folder with MKV files to FLV is also supported: simply paste, drag and drop it, or use the ADD FOLDER button.
Click or tap on FLV from the list of target formats
You could also use the search box at the top right to quickly find the format you need, whether it's FLV or something else.
Get your FLV files after MConverter has finished processing them
Click on DOWNLOAD ALL to save your FLVs to your default downloads folder, or select SAVE TO to choose another location.
You can also configure automatic file downloads during the conversion process or in the settings menu. When enabled, each FLV file is downloaded as soon as its conversion is complete, without waiting for the others to finish.
If supported by your device, you'll see a Share icon, allowing you to directly send converted files to other apps.

Format description
MKV files are MatrosKa Video files. Like the Russian Matryoshka doll, which contains multiple smaller dolls nested inside each other, the MKV format can contain multiple video, audio, and subtitle tracks inside a single file. This makes it convenient to have one video with a number of audio and subtitle tracks in different languages, all inside a single playable file.

FLV is a Flash video file. It was created for online streaming of video content using the Adobe Flash Player. However, since Flash reached end-of-life in 2020, the video format is now only used by Adobe Animate and playable by some third party apps like VLC.
Common questions about converting MKV to FLV
Can I convert MKV to FLV in bulk?
