WhatsApp tips

📏

WhatsApp limits video attachments to 16 MB per message. Keep your compressed video well under this to ensure reliable delivery.

📐

WhatsApp displays video at 720p or lower. Compressing to 720p before sending prevents WhatsApp from doing its own aggressive re-encode.

📱

Recipients often watch on mobile screens — 480p is visually identical to 720p at phone viewing distances and is significantly smaller.

💡

MP4 (H.264) is the most compatible format for WhatsApp across all devices. WebM is not universally supported on older Android versions.
