Frequently Asked Questions
Yes, this tool is 100% free to use. There are no hidden fees, watermarks, or limits on the number of videos you can compress.
No. All processing happens locally in your browser using the WebCodecs and MediaRecorder APIs. Your video never leaves your device, ensuring maximum privacy and security.
Since we are re-encoding the video frame-by-frame in real-time within your browser, the process generally takes about as long as the video's duration. Faster devices may process slightly quicker.
This tool works best on modern browsers like Chrome, Edge, and Firefox which support the MediaRecorder API effectively. Safari support is available but may default to MP4 format.
