Typical compression reduces file size by 40-80% depending on the source video's encoding and your chosen quality settings. A 500MB raw video file can often be compressed to under 100MB while maintaining visually acceptable quality. The tool lets you preview before downloading.

Some quality loss is inherent in compression, but it's usually imperceptible at moderate settings. The tool uses efficient codecs like H.264 and H.265 to minimize visible artifacts. For social media uploads, the difference between the original and compressed version is typically unnoticeable.

Yes, the tool is completely free with no watermarks or sign-up required. You can compress videos up to 500MB directly in your browser. Processing happens locally on your device, so there are no server upload wait times for most files.

Absolutely. Most email providers limit attachments to 25MB. Use the compression slider to target a file size under that limit. For a 2-minute 1080p video, medium compression typically brings the file well under 25MB while keeping it watchable.

Compression reduces file size by optimizing the video encoding without changing the content or duration. Trimming shortens the video by cutting out portions from the start, middle, or end. If you need to shorten your video instead, use our video trimmer tool.
