Frequently asked questions

How to convert AVI to MKV in ConvertLab?+

Choose your AVI file, select MKV, then proceed to preparation. Check the displayed options and click "Start conversion." After processing, download the result and open it in your target application. Simply selecting an output does not send your file.

Is the conversion from AVI to MKV free?+

€2 per month, renewed automatically. Turn off renewal in your account before the next billing date. Access continues until the end of the paid period. An Internet connection is required. File size limits and format compatibility still apply.

What elements should be checked in the result?+

Read the beginning, middle, and end on the target device. Check the duration, audio synchronization, tracks, and subtitles. Keep the original file for a new edit.

How to choose between MP4, WEBM, and MKV?+

MP4 is suitable for many sharing purposes; WEBM is particularly intended for web playback. MKV may be better suited for content with multiple tracks. Look at the outputs offered for your file and test the result on the player you will actually use.

Can I extract only the audio from my video?+

Yes, if MP3 is listed among the outputs of your source. Add the video, choose MP3, and start the conversion. The file must contain an audio track: a silent video cannot produce a sound recording.

Why am I being offered MKV for tracks and subtitles?+

Not all outputs retain the same tracks. If the engine indicates that a MKV container is required, go back to the output selection and choose MKV instead of forcing a conversion that would remove elements. This output may fall under NoLimit.

What to do if the conversion fails?+

Read the displayed message: a size limit, a reached quota, and an unsupported format require different actions. Check that the file opens locally, then try again with a lighter copy if necessary. If the problem persists, contact support with the formats, size, and error message, without attaching sensitive data.
