Why this matters
WhatsApp limits video attachments to 16MB. A 30-second iPhone video at 4K is roughly 100–170MB. Even at 1080p, a one-minute clip is 60–120MB. The video you shot at dinner is 10 times too large to send.
WhatsApp will automatically compress videos when you send them — but it does it aggressively, and the result often looks terrible. Compressing yourself gives you control over the quality tradeoff.
Frequently asked questions
What is WhatsApp’s video size limit? 16MB per video attachment. This applies to personal chats and group chats.
What resolution should I use for WhatsApp? 720p (1280x720) at medium quality usually produces clean, small files. 1080p works too but the file will be larger. 4K is overkill for a phone screen.
How long a video can I send on WhatsApp? There’s no hard time limit — it’s about file size. At 720p medium quality, you can usually fit 1–3 minutes under 16MB.
Will the video look bad after compression? At reasonable settings, no. You’ll lose some fine detail compared to the original 4K, but on a phone screen the difference is hard to spot. Aggressive compression (very low bitrate) will introduce visible blocking artifacts.
Can I compress multiple videos at once? Desktop app supports batch compression. Browser handles one file at a time.
