MKV to FLV API

Convert MKV videos to FLV format for compatibility, delivery, and playback across devices and platforms.

MKV FLV Video to video

Overview

Why convert MKV to FLV?

MKV to FLV conversion is typically driven by playback compatibility, file size, delivery requirements, and platform support. It is useful when a source video works in one workflow but needs a more widely accepted output format.

Converterer handles these conversions through API-driven and automation-first workflows rather than one-off manual file handling.

Common use cases

  • standardise uploaded videos into a more compatible delivery format
  • prepare videos for browsers, devices, customer downloads, or publishing pipelines
  • reduce friction when a source container is awkward for downstream tools

Quick example

Convert MKV to FLV in one request.

mkv-to-flv.sh bash
# Submit a MKV to FLV conversion, get an ID back instantly.
curl -u "$CONVERTERER_API_KEY:" \
  https://api.converterer.com/convert \
  -F input=@source.mkv \
  -F output_format=flv

# → {"id":"9f1a8e7c-1b9b-4f0a-9d2c-1a2b3c4d5e6f", "status":"queued"}
# The FLV result lands at <your-destination>/<id>.flv when done.
# Subscribe to a webhook to be notified the moment it's ready.
