Video compressor

Choose a video, a quality and a resolution, then press Compress video. The compressor re-encodes it as an H.264 MP4, the format every platform and phone plays, and shows the size before and after. Lowering the resolution to 720p usually cuts the file by more than half. It runs in your browser, so there's no upload and no file size limit beyond your device's memory.

Which settings to pick

• To send on WhatsApp, email or Slack: 720p, medium. Clear on a phone, small enough to send.
• To post on social media: 1080p, medium. Platforms compress uploads again, so a smaller file loses little.
• To keep a copy small: 480p, low or very low.

Resolution means the short side of the video, so it works for vertical and horizontal videos alike. The compressor never makes a video bigger than its source.

Why it takes a while

Compression re-encodes every frame. Your browser uses the device's hardware video encoder when it has one, which is usually faster than real time on a recent laptop or phone. A long 4K recording still takes minutes; keep the tab open until it finishes.

Other tools

To cut a section out before compressing, use trim video. To change the shape for Reels, Shorts or TikTok, use the video resizer.

Common questions

How do I compress a video without losing quality?

Keep the resolution your viewers need (1080p for social media) and pick medium quality. Platforms re-compress uploads anyway, so a smaller file loses little.

Is the video compressor free?

Yes, with no file size limit beyond your device's memory, no watermark and no upload.

Why is compressing slow?

Every frame is re-encoded. Your browser uses the device's video encoder when it can, but a long 4K recording still takes minutes.

What size should a video be for WhatsApp or email?

720p at medium quality is clear on a phone and small enough to send.
