Why Compress With Fizzly
Massive Size Reduction
Achieve up to 90% file size reduction using advanced encoding. A 1GB video can become 100MB without noticeable quality loss.
Quality Control
Choose from preset compression levels or fine-tune bitrate settings. Preview results before downloading.
Private Processing
Videos stay on your device throughout the compression process. Nothing is uploaded to external servers.
Fast Compression
Hardware-accelerated encoding leverages your GPU for rapid processing. Compress HD videos in minutes.

How to Compress Videos
Load Your Video
Drop a video file or browse to select. Supports MP4, WebM, MOV, and more.
Select Compression Level
Choose light, medium, or high compression based on your needs.
Compress & Save
Process the video and download your smaller file instantly.
Applications
When to Compress Videos
Email & Messaging
Shrink videos to fit email attachment limits (typically 25MB) or messaging app restrictions.
Storage Optimization
Free up space on your device or cloud storage. Store 5-10x more videos in the same space.
Faster Uploads
Reduce upload times to social media, video platforms, or file sharing services.
Web Performance
Optimize videos for websites. Smaller files mean faster page loads and better user experience.

Frequently Asked Questions
How much can I compress my video?
Compression rates depend on the source video. Videos with high bitrates (like raw camera footage) can be reduced by 80-90%. Already compressed videos may only reduce by 30-50%. Our presets are optimized to maximize reduction while preserving quality.
Will compression reduce video quality?
All compression involves some quality trade-off, but modern codecs are highly efficient. With medium settings, most viewers cannot perceive quality differences. Light compression is virtually indistinguishable from the original.
What determines the output file size?
Output size depends on video duration, resolution, complexity (motion, detail), and your selected compression level. High-motion videos and those with lots of detail compress less efficiently than static content.
Can I compress 4K or long videos?
Yes, but processing time increases with resolution and duration. 4K videos take longer due to the larger number of pixels. For best results, ensure your device has sufficient memory and close other applications.
Which compression level should I choose?
Light: archival or when quality is critical. Medium: general use, social media, sharing. High: email attachments, storage-constrained situations. Start with medium and adjust based on results.
Understanding Video Compression
Video compression works by removing redundant information between frames and reducing bitrate. Modern codecs like H.264 and VP8 are remarkably efficient, allowing significant size reduction with minimal perceptible quality loss. The optimal compression level depends on your content type and intended use.
