How to Convert and Compress Videos Online for Free

Video files come in dozens of formats, and not all devices or platforms support every format. Whether you need to convert MOV to MP4, extract audio from a video, or compress a large file for sharing, online video tools make it easy.

Common Video Format Conversions

MOV to MP4

Apple devices record video in MOV format, but MP4 is more universally compatible. Converting MOV to MP4 ensures your videos play on any device or platform.

WEBM to MP4

WEBM is common for web videos but not widely supported by video editors. Converting to MP4 gives you more flexibility.

AVI to MP4

AVI is an older format that produces large files. Converting to MP4 maintains quality while significantly reducing file size.

Video Compression: Reducing File Size

Large video files are difficult to share via email, messaging apps, or social media. Here's how compression works:

How Video Compression Works

Video compression reduces file size by:

Reducing resolution: 4K → 1080p can cut size by 75%

Adjusting bitrate: Lower bitrate = smaller file

Using efficient codecs: H.264 and H.265 offer excellent compression

Quality vs. Size Trade-offs

Light compression (CRF 20-23): Nearly identical quality, 30-40% size reduction

Medium compression (CRF 24-28): Good quality, 50-70% size reduction

Heavy compression (CRF 29-35): Noticeable quality loss, 70-90% size reduction

Extracting Audio from Video

Tips for Video Optimization

Always use MP4 with H.264: It's the most compatible format

Match resolution to use case: Don't upload 4K video to social media

Compress before uploading: Platforms re-compress anyway, so starting with an optimized file gives better results

Keep originals: Always save the original file before compressing

Conclusion

Free online video tools eliminate the need for expensive software like Adobe Premiere or Final Cut Pro for basic video tasks. Convert formats, compress files, and extract audio — all from your browser.
