Compress video for WhatsApp

WhatsApp crushes video quality when you send as media. Send it as a document instead — compressed to exactly 16 MB — and keep far more quality.

The 16 MB trick, explained

WhatsApp technically allows large documents — but when you send a video the normal way (as media), WhatsApp re-compresses it aggressively and it comes out blurry. The workaround power users know: send it as a document (attach → Document → choose video). Documents aren't re-compressed.

16 MB is the sweet spot: small enough to send and download quickly on mobile data, large enough for good-looking short clips. Compress to exactly 16 MB above, then attach the result as a document — your recipient gets the file untouched, at the quality you chose.

FAQ

How do I compress a video to exactly 16 MB for WhatsApp?

Select the WhatsApp 16 MB preset above and hit Compress. VidSizer computes the exact bitrate for your clip and verifies the output is under 16 MB before you download it.

Should I send video as media or as a document on WhatsApp?

As a document, if you care about quality. Media messages get re-compressed by WhatsApp; documents arrive exactly as you sent them.
