    How to use the WhatsApp Video Converter

    1. 1

      Choose the video that WhatsApp rejected (MKV, AVI, HEVC MOV, WEBM…).

    2. 2

      Optionally tap 16 MB to keep it as normal media.

    3. 3

      Press Convert and share the new MP4 to WhatsApp.

    Why WhatsApp rejects videos

    WhatsApp reliably plays only MP4 with H.264 video and AAC audio. Videos in MKV, AVI, WEBM, or HEVC from newer iPhones and some Android phones are often refused or show a black screen. This converter always re-encodes to H.264 + AAC at 720p, the combination WhatsApp handles best.
