All major formats including MP4, MOV, MKV, AVI, and WebM.
What is the maximum file size supported?
We recommend files under 2GB. Larger files may take longer to process.

No. All compression happens locally in your browser. Your video files never leave your device.
How much can file size be reduced?
Typically 50%-90% reduction, depending on the original encoding and quality settings.
Can I specify a target file size?
Yes. Enter your desired target size (e.g., 25MB for email attachments) and the system will automatically adjust compression parameters.
