Frequently Asked Questions
What is WhatsApp's video file size limit?
WhatsApp enforces a strict 16MB file size ceiling for videos sent as media attachments on both mobile and WhatsApp Web.
Why does WhatsApp Web fail to send certain MP4 files?
WhatsApp Web requires videos to be encoded with the H.264 video codec and AAC audio in an MP4 container with faststart metadata. ClipShrink automatically applies these exact compatibility standards.
Can I compress videos for WhatsApp status updates?
Yes. Compressing your video under 16MB prevents WhatsApp from aggressively re-compressing and blurring your status videos on their servers.
