Does converting MKV to FLV reduce quality?

Quality changes depend on the specific MKV and FLV formats and codecs. Converting between two lossy formats (like MP4, MP3, AAC, OGG Vorbis, WebM VP9) involves re-encoding which *can* slightly reduce quality, but our online converter uses high-quality defaults to minimize this. Converting from a lossless format (like WAV, FLAC, AVI/MOV with lossless codecs) to a lossy one *will* reduce quality to achieve smaller file sizes. Converting *to* a lossless format generally preserves the source quality (but won't improve it if the source was lossy). FrameNet aims for the best possible quality output for your chosen FLV format.

Will the FLV file size be different from the MKV file?

Generally, yes. Converting from a more compressed format like MKV to a less compressed or lossless format like FLV will likely result in a larger file size. Use our free online converter to see the exact result for your file.

How fast is the MKV to FLV conversion process?
