Compress Video for WhatsApp (Under 16 MB) — Free, No Upload
WhatsApp re-compresses every video you send, sometimes destroying quality. Pre-compressing to a sensible size keeps quality predictable and sends faster.
Step-by-step
Trim long pauses
WhatsApp shows the first 30 seconds inline. Trim the video to the most important moments first.
Compress to 720p, CRF 28
Open the Compressor, set 720p output, CRF 28 — that targets ~10–15 MB for a 60-second clip. Below WhatsApp's cap.
Send without re-compress
Smaller pre-compressed videos avoid WhatsApp's aggressive server-side re-encoding, which preserves quality.
Recommended settings

Quality check before publishing
- Play the first and last three seconds to catch bad trims, black frames, missing audio, or a visible jump at the end.
- Confirm the exported file matches the important settings above, especially duration, aspect ratio, resolution, codec, and file size.
- Preview once on the target platform or device before deleting the original source file.
- If the clip will be reposted publicly, strip metadata first and verify no private names, GPS data, or device fingerprints remain.

FAQ
Why does WhatsApp ruin my video quality?
WhatsApp re-encodes every video server-side to a low bitrate to save bandwidth. Sending a pre-compressed video the platform considers "small" reduces re-encoding aggressiveness.
Can I send a 4K video?
Not directly — WhatsApp downscales to 720p at most. Convert to 720p locally first to keep control over the look.
Does this run in my browser?
Yes — every step in this guide uses an in-browser FFmpeg WebAssembly tool. Your video never uploads to a server and never leaves your device.
