Frequently Asked Questions
Is my video uploaded to a server?
No. We utilize FFmpeg WebAssembly to process and compress your video completely inside your browser. Your video files never leave your device.
Why does it take so long to compress?
Because compression happens using your device's CPU rather than a massive cloud server, it relies entirely on your hardware capabilities. It is 100% private but slightly slower than server-side alternatives.
Is there a file size limit?
Browser limits typically restrict processing to files under 1-2 GB. If your browser runs out of memory, the page may crash. We recommend compressing files under 500MB for the best experience.
