Frequently Asked Questions (FAQ)
Q: Does this video compressor upload my video to any server?
No. All video decoding, resizing, bitrate calculation and encoding run 100% locally in your browser memory. Your videos never leave your computer or phone.
Q: How does the Target Size Guard ensure my file fits limits like Discord 25MB?
The engine calculates the required video bitrate by subtracting audio overhead and applying a safety margin. If the first pass exceeds your limit, it automatically recalibrates to ensure compliance.
Q: What is the difference between Native Engine and Compatibility Engine?
The native engine uses modern browser APIs with hardware acceleration where supported, loading in 0 milliseconds. The compatibility engine is loaded on demand for legacy containers without burdening initial page load.
