Why convert WEBM to MKV

MKV is a flexible container for storing video. WebM is converted to MKV for archiving and a single store, often without re-encoding the tracks.

How the conversion works

The file goes into an isolated server queue and is processed with ffmpeg. Progress is shown on the page, and the result is deleted automatically.

What to know

The current version copies the tracks into MKV without re-encoding, so quality does not change. Some players may not open MKV — keep MP4 for them.

Questions and answers

Why is processing done on the server?

A browser cannot reliably transcode video and audio. The server uses ffmpeg and processes one job at a time.

What are the limits?

Up to 100 MB, 5 minutes and Full HD for video. Audio has the same size and duration limits.

How long is the result stored?

The file is deleted after download or within an hour. The link stops working after deletion.
