Frequently Asked Questions
Is the video uploaded to a server?
No. All video processing happens entirely in your browser using the Canvas API and MediaRecorder API. Your video file never leaves your device and is never sent to any server, storage, or third party.
What video formats are supported?
The tool accepts MP4, WebM, MOV, AVI, and MKV files up to 2GB. Output format is WebM (for maximum compression) when available, or MP4 depending on browser support.
How much can a video be compressed?
Typical results range from 30% to 85% reduction. The more you lower quality and resolution, the higher the compression. For a WhatsApp video, selecting 60% quality + 480p usually reduces a 100MB file to 10–20MB.
Will there be a watermark?
Absolutely not. This tool adds zero watermarks. The output is clean and ready for WhatsApp, Instagram, Discord, email, or any other platform.
Why is compression slower than other tools?
Because this tool processes your video 100% locally in your browser, it cannot use dedicated server hardware. Processing a large 1GB+ file may take several minutes. Other tools appear faster because they upload your video to powerful servers — at the cost of your privacy.
