WebM ut MKV Quaestiones Frequentes de Conversionibus
How do I re-encode WebM to MKV without quality loss?
+
Upload your WebM file and set Quality to High Quality in the conversion options. That re-encodes the video at the highest quality setting (CRF 18 for H.264 and VP9 output), which keeps the most detail at the cost of a larger file. The default, Balanced, uses the standard setting. The MKV output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM.
Which codec does the MKV output use?
+
It depends on the MKV container. MP4, MOV and MKV output use H.264, which plays on practically every phone, browser and TV. WebM output uses VP9. AVI, WMV and MPEG output use the older codecs those formats were designed for.

Quae sunt variatioe in magnitudine inter WebM et MKV?
+
Same-codec re-muxes (e.g. WebM → MKV where both use H.264) produce nearly-identical sizes. Codec changes can swing the size dramatically: H.264 → H.265 typically halves the file at the same visual quality; H.264 → VP9 is roughly comparable.
Will the MKV file play on iPhone / Android / Smart TV?
+
