How to Compress Videos Online

Click the upload area and select a video file (MP4, WebM, or MOV).
Choose a quality preset — Balanced is recommended for most use cases.
Optionally change the resolution or output format.
Click "Compress Video" and download the result when it's ready.

Why Compress Videos?

Faster Uploads: Smaller videos upload faster to social media, cloud storage, and video platforms. Save time and bandwidth.
Save Storage: Reduce cloud storage costs and keep your media library manageable. A 1-minute 4K video can be over 500MB uncompressed.
Email & Messaging: Most email services limit attachments to 25MB. Compressed videos are easier to share via email, Slack, or messaging apps.
Web Performance: Embedded videos on websites load faster when compressed, improving user experience and reducing bounce rates.

Video Compressor FAQs

Common questions about compressing videos

Is this video compressor free?

Yes, completely free with no limits. Your videos are processed entirely in your browser using FFmpeg.wasm — nothing is uploaded to any server.

What video formats are supported?

You can upload MP4, WebM, and MOV files. The compressor can output MP4 (H.264) or WebM (VP9) formats.

How much can I reduce the file size?

Typical savings range from 30-80% depending on the source video, quality preset, and resolution settings. The Balanced preset usually achieves 40-60% reduction with minimal visible quality loss.

Will compression reduce video quality?

Some quality loss is inherent in video compression, but at the High Quality and Balanced presets the difference is virtually imperceptible to the human eye. You can preview the result before downloading.

Which quality preset should I use?

For most use cases, Balanced (CRF 28) offers an excellent trade-off between file size and quality. Use High Quality for professional work and Small File or Smallest for quick sharing via email or messaging apps.

Are my videos uploaded to a server?

No. All processing happens 100% in your browser using FFmpeg.wasm, a WebAssembly port of FFmpeg. Your videos never leave your device.

What is CRF (Constant Rate Factor)?

CRF is a quality parameter used by video encoders like H.264 and VP9. Lower values mean higher quality and larger files. A CRF of 23 is visually lossless, while 28 is a good balance. Values above 33 produce noticeably smaller files with visible quality reduction.

Can I compress a video and change resolution?

Yes. You can select a lower resolution (1080p, 720p, or 480p) alongside compression to further reduce file size. Downscaling from 4K to 1080p alone can reduce file size by 50% or more.

What is the maximum file size?

This tool accepts videos up to 500MB. Since processing happens in your browser, very large videos may take longer depending on your device's processing power and available memory.

Does compression preserve audio?

Yes. Audio is re-encoded at 128kbps AAC (for MP4) or 128kbps Opus (for WebM), which provides excellent audio quality at a small file size. The audio track is always preserved.

"Brilliant piece of software. Reasonably priced (vs Canva's outrageously expensive API), and despite a few intricacies with the editor, a really fully-featured document generation API. Really great support too from Pedro, the founder!"
