How to Compress a Video
1
Upload Video
Drag and drop your video file (MP4, MOV, MKV, AVI, WebM, or others) into the tool above, or click to browse. Up to 100 MB.
2
Choose Quality
Select a quality preset from Highest to Smallest. Optionally downscale the resolution to 1080p, 720p, or 480p for even smaller files.
3
Download
Click Compress Video and download your compressed MP4. See the savings percentage instantly.
Quality Presets Explained
| Preset | CRF | Typical Savings | Best For |
|---|---|---|---|
| Highest | 18 | 20–40% | Archival, professional editing, or when quality is paramount. Visually lossless for most content. |
| Balanced | 23 | 40–70% | General use — the recommended default. Great balance of quality and file size for sharing, uploading, and storage. |
| Good | 28 | 60–80% | Email attachments, messaging apps, or when file size matters more than pixel-perfect quality. |
| Smallest | 32 | 75–90% | Maximum compression for very limited storage or bandwidth. Some quality loss will be visible. |
Why Compress Videos?
- Email attachments — most email providers limit attachments to 25 MB. A one-minute 4K video from a phone can easily exceed 200 MB. Compression brings it within limits.
- Faster uploads — smaller files upload faster to YouTube, Vimeo, social media, cloud storage, and messaging apps like WhatsApp and Telegram.
- Save storage — phone videos at high bitrates eat through storage quickly. Compressing archived videos can free up gigabytes without visible quality loss.
- Web performance — compressed videos load faster on websites, reduce bandwidth costs, and improve user experience on slow connections.
- Sharing — messaging apps often have file size limits. A compressed video stays within WhatsApp’s 16 MB limit or Discord’s 25 MB limit while maintaining good quality.
Resolution Downscaling
Reducing resolution is the most effective way to shrink file size beyond what CRF alone achieves. A 4K video downscaled to 1080p can be 4× smaller with no visible difference on most screens.
| Resolution | Pixels | Best For |
|---|---|---|
| Original | Unchanged | Keep the source resolution. Best when you need full quality. |
| 1080p | 1920×1080 | Full HD. Perfect for YouTube, social media, and presentations. The sweet spot for quality vs. size. |
| 720p | 1280×720 | HD. Great for email, messaging apps, and mobile viewing. Significantly smaller than 1080p. |
| 480p | 854×480 | SD. Maximum size reduction. Good for previews, quick shares, or very limited bandwidth. |
Frequently Asked Questions
Typical savings range from 30% to 90% depending on the source video’s original encoding and your chosen quality preset. Phone recordings (often encoded at very high bitrates) compress especially well. The Balanced preset typically achieves 50–70% reduction with minimal visible quality loss.
All lossy compression involves a trade-off between file size and visual quality. The Highest preset (CRF 18) is considered visually lossless — the difference from the original is imperceptible to the human eye. The Balanced preset (CRF 23) is the recommended default, offering excellent quality with significant size savings. Lower presets sacrifice some quality for smaller files, which may be noticeable in fast-motion scenes or fine details.
The tool accepts MP4, MOV, MKV, AVI, WebM, WMV, FLV, MPG, MPEG, 3GP, M4V, TS, and MTS files up to 100 MB. The output is always MP4 with H.264 video and AAC audio — the most universally compatible format across devices, browsers, social media platforms, and messaging apps.
CRF (Constant Rate Factor) is the quality control parameter used by H.264 encoding. It ranges from 0 (lossless, huge files) to 51 (worst quality, tiny files). Lower CRF = higher quality and larger files. Our presets use: CRF 18 (Highest/visually lossless), CRF 23 (Balanced/recommended), CRF 28 (Good/smaller), and CRF 32 (Smallest/maximum compression). CRF 23 is the FFmpeg default and provides an excellent quality-to-size ratio.
