Frequently asked questions
What is the most effective way to compress a video file without ruining quality?
Downscaling resolution (e.g., from 4K to 1080p or 720p) combined with moderate H.264 CRF compression yields massive size reductions of 70% to 90% while keeping visual playback sharp.
Can I set an exact target file size (e.g. 25MB for Discord)?
Yes. You can select target size presets (8MB, 25MB, 50MB) and the engine calculates the required combined audio and video bitrates automatically based on video duration.
Are my private videos uploaded to any external server?
No. The compression pipeline executes entirely within your browser sandboxed memory. No video chunks or audio streams are ever uploaded.
