Do you have a MKV video or movie file that will not open correctly? If so, our free-to-use MKV video repair tool may be able to help. Our tool analyses the content of your MKV file and is able to determine if the file content is valid. Our tool will let you know what is wrong with your MKV file and attempt to fix it.
Or drag and drop your files here to upload.
A maximum of 20 files can be uploaded at once.
Here are 3 simple steps to repair your MKV using our fast and free repair tool.
No. Our MKV repair tool will not adjust the resolution or quality of the repaired file.
Yes! Our MKV repair tool is 100% free to use.
No, you can repair as many files as you wish. We do not have any limits when using our MKV repair tool.
We aim to process MKV repairs as quickly as possible; this usually takes around 5 seconds; however, this may be longer depending on the file size and data needed to be repaired.
Once your MKV has been selected, it will undergo some initial checks to verify that the file has some basic information. If the initial checks pass, we then upload the file to our servers for more detailed analysis.
Yes, of course it is! Your MKV, once repaired, is deleted 15 minutes after upload, and any download link will expire after this time.
Yes! Our MKV repair tool will run on any system with a modern web browser.

An MKV file, or Matroska Video File, is an audio/video file format created to store multimedia data in a highly compressed format. The MKV format supports a wide variety of audio and video codecs and is a popular format for distributing video files.
The format itself is a container format, meaning it supports many different audio and video tracks, all using different codecs. Along with audio and video, other data, such as chapters, markers, sub-titles, and other useful data, can be stored within the file.
Support for editing MKV files is widespread, with most video editing applications able to open MKV files. Video playback software, however, can sometimes struggle to playback MKV files if they are not equipped with the correct codecs.
MKV files are all binary format in nature, storing video frames in a compressed format dictated by a bit-rate setting. This bit-rate setting is often located within the file header bytes, a sequence of bytes unique to a particular file format. The header bytes not only identify the type of video file to be played but also compression and codec settings.
By analysing the MKV file header bytes, our tool is able to calculate the expected length of the video file and also perform other integrity checks to ensure the video file is what the header bytes claim it to be. Our MKV repair tool can check the header byte sequence relatively quickly and report any immediate issues right away.
As mentioned above, within the MKV file data are values that determine how aggressive the compression algorithm is when it comes to balancing file size with playback quality. Our tool will not alter any bit rate or other quality settings; these will be preserved during any repair performed on the uploaded file.
Our tools support most common codecs, allowing our tool to parse the MKV file content when looking for issues with the playback of the file.
