Frequently asked questions

AVI to MKV FAQ

How do I convert AVI to MKV?

Choose a supported AVI video, review the quality, resolution and frame-rate settings, start conversion and download the MKV result.

Are my files uploaded?

No. Supported video conversion runs locally in your browser, so the source file is not uploaded to zer.ai.

Will conversion change video quality?

Transcoding creates a new encoded file. Choose high quality when visual fidelity matters, or a smaller setting when output size is more important.
