Compress Video to 16MB for WhatsApp

WhatsApp supports documents far larger than 16MB, but a compact file sends faster and is easier on mobile data. This preset uses 16MB as a conservative sharing target while keeping the encoding under your control.

Why use a compact WhatsApp preset

WhatsApp's official document limit is up to 2GB, so 16MB is not a platform maximum. It is simply a practical preset for short clips that need to send quickly on slower connections or through data-constrained chats.

Frequently asked questions

Why do my WhatsApp videos look blurry?
WhatsApp re-encodes media uploads at a low bitrate to save bandwidth. Pre-compressing to the target size and sending as a document bypasses WhatsApp's own encoder, preserving your chosen quality.
Media vs document — which should I send?
Sending as a document is useful when preserving the chosen file is important. WhatsApp documents can be up to 2GB, so choose the target size based on upload speed and recipient convenience.
