# Compress Video for WhatsApp

> Shrink videos to a WhatsApp-friendly size on your own terms, instead of letting the app crush them.

Shrink any video to an exact target file size in MB or to a quality preset — ideal for getting under email, WhatsApp, Discord, or Slack limits. Uses hardware-accelerated WebCodecs H.264 encoding when the browser supports it (Chrome, Edge, Safari) and falls back to WebAssembly otherwise. Optional downscaling; no upload; up to 1 GB.

## Media message or document?

WhatsApp gives you two ways to send a video. As a regular media message it plays inline, but WhatsApp re-encodes it heavily and long videos get refused. As a document it arrives exactly as you sent it — no recompression — but the recipient downloads the full size. The sweet spot for most videos: compress here to around 16 MB, then send as a document. You keep the quality decision, and it stays fast to send on mobile data.

This page presets a 16 MB target; raise or lower it freely. For family videos shot on modern phones, adding the downscale-to-1080p option often halves the size with no visible difference on a phone screen.

## Frequently asked questions

### What are WhatsApp's video limits?

Videos sent as media are aggressively re-compressed by WhatsApp, with 16 MB being the classic size guideline (roughly 90 seconds to 3 minutes depending on quality). Files sent as documents can be much larger and skip recompression — compressing to a reasonable size first keeps documents quick to send and download.

### Why compress myself instead of letting WhatsApp do it?

WhatsApp's automatic compression is tuned for speed, not quality — it can leave videos blurry and blocky. Compressing locally first lets you pick the size-quality trade-off, and sending the result as a document delivers it to the recipient untouched.

### How does the compressor hit the exact size?

You set a target size and the compressor calculates the video bitrate needed to land just under it, leaving a small margin for the container. If the target is too small for the video length, it warns you before starting instead of producing unwatchable quality.

### How much quality will I lose?

It depends on how far the video needs to shrink. Halving a file is usually invisible; squeezing a 500 MB video under 10 MB is very noticeable. Two things help a lot: trim the video to just the part you need first, and enable the resolution downscale option — fewer pixels means more bitrate per pixel.

### Is it really free?

Yes. The video compressor is completely free, with no signup, watermarks, or limits. We make money from our video translation service, not from this tool.

### Do you upload my files?

No. The compression happens locally in your browser using WebAssembly. Your file never leaves your device — you can even disconnect from the internet once the page has loaded.
