Video Compressor Frequently Asked Questions
Will the file always become smaller?
Usually, but not always. Already optimized videos can occasionally become larger if you choose a high quality preset.
What does CRF mean?
CRF controls visual quality. Lower values keep more detail and create larger files; higher values compress more aggressively.
Is my video uploaded to a server?
No. This tool processes your files locally in your browser. BeYourTools does not upload, store, or send your media to a processing API.
Does processing reduce the quality or resolution of my original video?
Trimming, cutting, and frame extraction keep your original video resolution and picture clarity. Our compressor tool lets you choose how much file size to shave off while keeping your picture sharp.
Are my personal videos uploaded to or viewable by anyone else?
No. All video editing happens right in your browser memory. Your files are never sent to our servers or saved anywhere online. Everything stays safe on your own device.
