How to send a video larger than 16 MB on WhatsApp
WhatsApp treats a video two different ways depending on how you attach it. Sent as media it is compressed hard and, on many versions, refused above 16 MB; sent as a document it goes through at full quality up to 2 GB. Knowing which to use solves most "file too large" moments; compressing or trimming solves the rest.

Quick answer. Fastest: attach the video as a document (Attach → Document → browse to the video) instead of from the gallery. WhatsApp sends it at original quality, up to 2 GB, and the recipient downloads it as a file. If it must play inline as a normal video message, compress it to under 16 MB first with the free browser compressor on this site, which targets the size exactly, or trim it to the part that matters. Both run on your device; nothing is uploaded anywhere except, eventually, to WhatsApp.

Step by step
- Decide: full quality for a client or a site walkthrough → send as a document. Quick clip to a family group → compress to 16 MB and send as media.
- Document route: in the chat, tap the attach icon, choose Document, then Browse other docs (Android) or Choose from Files (iPhone), and pick the video.
- Compress route: open Compress video to 16 MB, drop the video, pick 720p for anything over a minute, encode, download, send as media.
- Long video: open Trim Video, cut to the part that matters without re-encoding, then compress if still over the limit.
Tips that save a second attempt
- Sending as a document also stops WhatsApp from degrading the video; it is the right choice for property walkthroughs and anything a client will show on a TV.
- Status updates still cap at short clips; trim to the limit with the frame-exact trim tool rather than letting WhatsApp cut it.
- A 16 MB target at 1080p starves long clips; 720p at 16 MB looks better for anything beyond about a minute.
- On iPhone, Settings → Camera → Record Video at 1080p 30 fps halves file sizes for future recordings compared with 4K.
Frequently asked questions
Does sending as a document reduce quality?
No. The file is sent as-is, like an e-mail attachment. The recipient sees a file card and taps to download and play.
What is the actual WhatsApp video limit?
Documents: 2 GB on current versions. Media videos: compressed automatically, with a 16 MB cap on many versions and regions; larger media may be refused or heavily degraded. The 16 MB target is the safe choice.
Can I compress on the phone itself?
Yes. The compressor on this site runs in the phone's browser as well; it is slower than a laptop but works, and nothing is uploaded.
Is the video uploaded to Cortex?
No. Compression and trimming happen in your browser on your device.
