Yes! All compression happens locally in your browser. Your videos never leave your device or get uploaded to any server.
Compression depends on the original video. Typically, you can reduce file size by 30-70% with minimal quality loss. Higher compression will reduce quality more noticeably.
Low quality provides maximum compression (smallest file), while Ultra provides minimal compression (highest quality). Medium and High are good balances between size and quality.
No, compression only affects the bitrate (data rate). Resolution stays the same. For resolution changes, use our Video Resizer tool.
